We record with great regret the death
of Braam Le Roux after a long and
distinguished railway career lasting more
than 40 years. He was appointed CEO of
Spoornet in 1992, and held this position
until he retired in 2000.
In the words of Siyabonga Gama, current
CEO of Transnet Freight Rail, “Mr Le Roux’s
managerial leadership was recognised
globally and he had a passion for railway
innovation and technical applications.
His leadership qualities were not just
recognised and appreciated in South
Africa but in Africa as a whole. This was
evident from the numerous high positions
he held in rail organisations. He was the
fi rst President of the Southern African Rail
Association in 1992; he also served as
Chairman for the Metre Gauge Group of
International Railways (1995-2000), Vice
Chairman of the World Executive Council
of UIC between 1996-2000 and as Vice
President of the Institute of Railway Signal
Engineers from 1996 until now.
“Within our South African borders, Mr Le
Roux served in the boards of numerous
institutions such as, the Council of the Rand
Afrikaans University in Johannesburg,the
Engineering Council of South Africa and
the Executive Board of the SA Academy of
Engineers. Mr Le Roux was truly iconic and
his demise is a loss not only to Transnet but
to South Africa as a whole, as he played
such a pivotal role in the development of
our railway.”
I was devastated to hear the news. Braam
was a long-standing and valued friend of
Railways Africa. He was the very fi rst VIP I
interviewed when taking over the magazine
twenty years ago - and he didn’t give me
a hard time! He will be greatly missed, not
least for his sound advice on the many
occasions when I picked up the phone and
called for guidance.
All good things come to an end, they say,
and sadly this goes for great men too.
Without Braam, rail-related conferences
will never be the same.
We send our condolences to his family –
and to Transnet.

RAILWAY SAFETY REGULATORIntroduction to the Railway Safety Regulator
This is the fi rst in a series of articles
explaining the role and mandate of the
Railway Safety Regulator (RSR) in the
South African rail environment.
06
Prior to 2002, the rail industry in South
Africa was self-regulating. Operators set
their own standards, investigated their own
incidents and were accountable to no one
in particular for safety performance.
In addition, a confl uence of legislative and
operational factors contributed to a gap
in the railway environment where safety
was concerned. Neither the Occupational
Health and Safety Act (Act 85 of 1993)
nor the Mines Health and Safety Act (Act
29 of 1996) adequately address railway
operational safety. The Land Transport
Transitional Act 2000 does not provide for
railway operational safety.
This situation left existing operators with
no processes to verify railway safety
performance. Possible changes in both
the industry and government, and any
restructuring of railways, had the potential
to introduce more operators. More
interfaces between operators would then
result, with additional attendant risks to be
managed.
It is fundamentally wrong, it was concluded,
for operators to be both “player” and
“referee”, especially insofar as major
operators dominating the industry are
concerned. The creation of an independent
body to regulate railway safety was seen to
be essential.

RAILWAY SAFETY REGULATOR
Introduction to the Railway Safety RegulatorThis is the fi rst in a series of articles explaining the role and mandate of the Railway Safety Regulator (RSR) in the South African rail environment. It highlights the RSR’s key role in standardising safe rail operations in cooperation with neighbouring countries and the Southern African Development Community (Sadac).
and thereby the use of rail as an effi cient
mode of transportation will be encouraged.
This is a co-regulatory approach.
The RSR’s jurisdiction covers all rail
operations except those in amusement
parks and underground in the mines.
These operations span industry sectors
ranging from manufacturing, petrochemical
and tourism to commuter services. The
largest of these are Transnet Freight Rail
(TFR) and the Passenger Rail Agency
of South Africa (Prasa). Other smaller
operators range from small siding owners
(which use rail for loading and offl oading)
to municipalities, the surface lines on mine
property, and also manufacturing and other
concerns with extensive rail networks,
locomotives and other rolling stock within
their premises
The Act requires all railway operators to
apply for a Safety Permit from the Railway
Safety Regulator, prior to engaging in any
railway operation. This is a requirement for
all operators involved with the operation o
f any railway within the Republic with a
track gauge of 600mm or more.
The safety permit is issued once the RSR
has satisfi ed itself that the operators
have a sound Safety Management System
(SMS) in place. A SMS as defi ned in terms
of the Act means a formalised framework
for integrating safety into day-to-day railway
operations, and includes safety goals and
performance targets, risk assessments,
responsibilities and authorities, rules and
procedures, monitoring and evaluation
processes and any other relevant matter
prescribed by regulation. Up to mid-2011,
the RSR has successfully evaluated safety
management system reports and issued
safety permits to 280 operators, thereby
legalising rail operations.
In each case, the RSR monitors performance
to assess compliance by the operator with
its own SMS, including the conducting of
random and routine audits, inspections
and occurrence investigations. The RSR is
tasked with ensuring that new or modifi ed
technology addresses both operational
safety as well as environmental concerns.
Based on the results of monitoring the
safety performance of an operator, the RSR
may amend any condition of the Safety Permit.
The National Railway Safety Regulator
Act, 2002 (Act 16 of 2002) was tabled on
5 August 2002 and promulgated during
November of that year. The offi ce of
the Railway Safety Regulator (RSR) was
established during 2003.
The RSR’s mission is “To oversee and
promote safe railway operations through
appropriate support, monitoring and
enforcement guided by an enabling
regulatory framework.” Its vision is the
“Creation of a safe railway environment.”
Safe railway operations are vital to the
national economy and therefore critical to
the sustainability of our freight logistics and
public transport system.
It is recognised that, in terms of the Act, the
primary responsibility for safety lies with
the railway operator. It thus encourages
accountability and responsibility amongst
operators for the safety of their own
operations, and provides a suitable
framework for the improvement and
effi cient monitoring of safety performance
in the railway industry as a whole. Within
such a regulatory institution, the continuing
enhancement of railway safety is ensured,

OVERVIEW OF THE NRSR ACT
7Railways Africa June 2011 www.railwaysafrica.com
RAILWAY SAFETY REGULATOR
MANDATEThe RSR is a South African public entity, governed and
controlled by a board of directors appointed by the minister of
transport. The Board holds offi ce for a period of three (3) years.
The mandate of the RSR can be summarised as follows:
• To oversee safety of railway transport, while operators
remain responsible for managing safety of their operations;
• To promote improved safety performance in order to
promote the use of rail;
• To monitor and ensure compliance through the conducting
of audits, inspections and occurrence investigations;
• To conclude appropriate cooperative agreements or other
arrangement with organs of state to ensure effective
management and overseeing of safe railway operations
and to minimise duplication;
• To collect and disseminate information relating to safe
railway operations;
• To develop, adopt or accept standards and regulations for
safe railway operations;
• To collaborate with and conclude contracts, where
appropriate, with any person, body or institution with
the view to furthering the objects of the RSR, including
scientifi c and technical information, and training;
• To promote the harmonisation of the railway safety regime
of South Africa with SADC railway operations.
The next article in the series will examine achievements by the RSR
in conducting operator audits and inspections, as well as post-
accident investigations, the issuing of improvement directives
and other interventions aimed at addressing railway safety.
The RSR’s interventions are informed by overall governmental
priorities, the Department of Transport’s strategic priorities in
the medium term, the RSR’s mandate and key safety challenges
in the railway environment.
The medium term interventions of the RSR are thus to achieve
the following fi ve key strategic goals:
• A conducive regulatory safety environment;
• Improved levels of safety and security in the railway
industry;
• RSR: A recognised authority in the provision of railway
safety expertise;
• Sustainable railway industry capacity; and
• Sustainable institutional effectiveness.

2. Tamping Process DescriptionThe working units of a tamping machine are the tamping units
which are located between the bogies or axles. Refer to Figure 2
for the layout of a typical but simple tamping unit for illustration
purposes.
Over a period of time however, the track geometry will deteriorate
again. This period of deterioration is very important to the railway
engineer since this will determine the track tamping cycle. The
longer the tamping cycle, the less the disruption to traffi c, less the
demand on railway resources and the cheaper the track will be
over its life-cycle. The durability of the tamping process therefore
plays an important role.
Durability can only be proven over time with traffi c running over the
track. This poses a problem since many factors other than tamping
can infl uence durability, e.g fouled ballast, rail defects, joints and
welds in the track, fl at wheels on wagons, etc.
This article will therefore show scientifi cally why the Plasser
tamping process is so durable by drawing from various research
studies done by prominent international railway engineers,
researchers and academics, Plasser & Theurer, Plasserail and
Transnet Freight Rail.
1. IntroductionUnder repeated loading from traffi c, the track progressively
moves vertically and laterally, causing deviations from the desired
geometry. Ballast tamping is the process used to re-arrange the
ballast under the sleeper to restore the vertical and horizontal
alignment and elasticity of the track structure.
Figure 1: Poor track geometry.
It is the tamping units that carry out the tamping process as
illustrated in Figure 3. This acts as background in determining
and explaining those parameters of tamping that will infl uence the
durability of the tamping process.
Step 1 – A basic tamping machine indexes forward and comes to
a standstill with its tamping units over the sleeper to be tamped.
The tamping tines of the tamping unit straddle the sleeper on
both sides.
All Plasserail tamping machines are equipped with a fully
automatic three-point measuring system consisting of a rear,
centre and front measuring trolley connected by a lifting wire
and an alignment wire which establishes the vertical and
horizontal position of the track in order for defects to be
corrected and for instating a uniform lift and line to the track.
Step 2 – The combined lifting and aligning unit works in
conjunction with the measuring system and grips the rail under the
crown, lifts the track to a predetermined height while correcting
any vertical defects in it and at the same time slews the track to
correct the horizontal alignment. Without a lift the ballast stones
will not have enough space to rearrange. Within a short time, the
track will revert back to its position before tamping took place.
Step 3 – After the track has been lifted and aligned to the desired
position, the tamping units are lowered. The tines of the tamping
units enter the ballast and come to rest at a predetermined depth. Figure 2 : Movement of tines due to vibration.

The tines perform a squeezing motion which compacts ballast
underneath the sleeper in the void created by the lifting process.
In practice it soon became very clear that by merely squeezing
the ballast into position under the sleepers requires huge forces
and does not provide even compaction. The reason is that the
ballast stones are unable to re-arrange in relation to one another.
Forcing the ballast stone will result in it being crushed.
Vibration of the tamping tines is therefore necessary to excite the
ballast stone, creating a liquid effect which permits it to re-arrange
and settle in a dense matrix. Vibration also greatly reduces the
force required for the tamping tines to penetrate the ballast.
The vibration of the tamping tines is induced by an eccentric shaft
within the tamping unit. The cylinder assembly which produces
the squeezing force of the tines also transfers the vibration caused
by the off-centre cam of the eccentric shaft. This will cause the
tines to move forward and backward around the stationary pivot
point. See Figure 2. The revolution speed of the eccentric shaft
determines the frequency of the vibration and the size of the off-
centre cam on the shaft determines the amplitude of the vibration.
Step 4 – The cylinder assembly exerts a force on the tine arms
which perform a squeezing motion of the tines. The tines compact
ballast underneath the sleeper in the void created by the lifting
process. The tamping machine indexes forward to the next sleeper
and the process repeats itself.
3. Operating Parameters of the Plasser Tamping Process That May Infl uence Durability
3.1 Lifting HeightAs mentioned before, a predetermined minimum lifting height
is instated in the track to ensure that its vertical level is uniform
behind the machine and to provide the necessary space for the
ballast stones to rearrange in relation to one another. The value of
this minimum lifting height has been thoroughly researched due
to its effect on the durability of the tamping process.
In the book Track Geotechnology and Management by Prof Ernie
Selig and John Waters, the lift given by a tamping machine is
plotted against the settlements that occurred in the subsequent
66 weeks under traffi c loading. The objective was to determine the
residual lift achieved after traffi c as a measure of durability. See
Figure 4 for the results.
Each red dot on Figure 4 corresponds to a sleeper end. A trend can
clearly be identifi ed and can be represented by the two red lines.
Step 1
The tamping machine stops over
the sleeper to be tamped.
Step 2
Lifting units lift the rail and sleeper
to pre-determined height.
Step 3
Tines enters ballast and stops at
pre-determined depth.
Step 4
Cylinder assembly performs squeezing
action and compacts ballast in the void.
Figure 3: Tamping process description.
Figure 4 : Track lift vs settlement.
12 Railways Africa June 2011 www.railwaysafrica.com
PLASSERAIL
It can be seen that for relatively low lifts, the lift given by the
tamping machine (for example 10mm) is less than the settlement
(approximately 13mm) that occurred in the subsequent 66 weeks.
A possible explanation for the high settlement that occurred with
a low tamping lift may be that by squeezing and vibrating the
ballast, the ballast stone will expand upwards into the void but,
due to the limited void space, it cannot re-arrange completely nor
interlock in a new stable position.
Re-imposition of the vertical traffi c loading will re-compact the
ballast and the particles will adopt their original positions with
respect to each other. The track will thus revert to its original
irregular geometry, also referred to as the memory of the track.
However, where the two red lines cross, the lift given by the tamper
is more or less equal to the settlement as measured.
During maintenance tamping at Plasserail the track is lifted to an
approximate minimum of 20mm to ensure a residual lift that will
achieve a lasting improvement in the track condition.
3.2 The Frequency of Tine VibrationsThe durability of the tamping process is also infl uenced by the
frequency of the tamping tine’s vibration. Refer again to Figure 2.
As can be seen from Figure 5, frequencies in the range of 16 to
25Hz produce a lasting lift, whereas frequencies exceeding
40Hz result in a negative settlement of the sleeper. This negative
settlement can be attributed to a phenomenon referred to as
the plasto-elastic deformation; also known as liquefaction of the
ballast stone.
The higher the plasto-elastic deformation, the more liquid the
ballast stone becomes and the more diffi cult it is to pack it in a
dense matrix. It just fl ows away.
At a frequency of 16-25Hz, the tines experiences diffi culty in
penetrating the ballast. The graph in Figure 5 shows that the ideal
frequency is between 25 and 40Hz and will have to be:
• the highest possible frequency for ease of penetrating the
ballast;
• a frequency low enough to produce a lasting lift; and
• a frequency having the lowest possible plasto elastic
deformation properties.

Researchers have plotted the relative plastic deformation of
ballast against different frequencies. Figure 6 shows that at a
frequency of 35Hz, a minimum deformation of the ballast occurs,
meaning that at this frequency, the highest possible durability
is achieved by tamping (based on clean and properly graded
ballast). Thus, the optimum tamping frequency and the frequency
used by all Plasserail machines is 35Hz.
3.3 The Amplitude of Tine VibrationsThe distance the entire cylinder assembly moves horizontally away
from the centre of the eccentric shaft is determined by the size
of the off-centre cam on the shaft. This distance travelled by the
cylinder assembly determines the amplitude of the tine as the
tine arm pivots around a stationary point. The tine will vibrate
forward and backward, the total distance representing twice the
amplitude. Refer to Figures 7 and 8.
Figure 6 : Determining minimum plastic deformation.
Figure 7 : Amplitude.
Figure 8 : The tine vibration sine wave.
16 Railways Africa June 2011 www.railwaysafrica.com
PLASSERAIL
Practice has shown that amplitude greater than 5mm causes
crushing of the ballast whereas amplitude less than 5mm
fails to transfer the energy of the vibration to the ballast stone.
The amplitude used on Plasser tamping machines is therefore
approximately 5mm.
3.4 Tamping DepthWhen the tamping tines enter the ballast, they come to rest at a
pre-set depth. The tamping tine depth has great practical
signifi cance for durable packing of the ballast under the sleeper.
When the depth is too shallow, the tines strike against the
sleepers, and when the depth is too deep, there is uneven and
incomplete packing of the sleeper bearing area. This can be
attributed to the liquefaction of the ballast and the ability of the
stone to fl ow over the tamping tine plate.
The ideal setting range of the tamping depth is approximately
15mm free space between upper edge of the tamping tine plate
and the lower edge of the sleeper.
On Plasser tamping machines, the tamping depth is controlled
electronically to 15mm under the sleeper.
3.5 Squeezing Action of the Tines – Synchronous or Asynchronous Pressure Control
When the tines enter the ballast bed, the cylinder assemblies
exert a force on the tine arms to perform a squeezing action
which packs the stones in the void under the sleeper created by
the lifting process.
If all tines are forced to travel the same distance during the
squeezing action (synchronous tamping), this may result in
under-compaction - if there is an obstruction which prevents full
tine-squeeze distance. This may also result in crushing of the
ballast stones.
Only the asynchronous tamping process, whereby all tamping
tines receive the squeezing pressure from the same circuit, fulfi l
the requirement of a homogenous compacted ballast bed. Should
one tine experience an obstruction, the other tine will continue
through its squeezing motion.
All Plasser machines use the asynchronous pressure control
system.

During the oscillation the tine will create a void in the ballast of at
least twice the size of the amplitude i.e 5mm forward and 5mm
backward of the zero position (Figure 11).
During the forward motion of the vibration cycle, impact with the
ballast stone will only take place once the tine has travelled the
total void distance, in other words, if the tine was not moving
forward at a squeezing speed, impact would have taken place at
the turning point of the vibrating cycle.
However, impact will occur before the tine has completed its
forward cycle of the vibration because the tine is at the same time
moving forward at its squeezing speed (see Figure 12).
After impact the tine tip will remain in contact with the ballast
until the oscillation starts its backward movement. This means
that only during a short phase of the forward movement will the
tine make contact with ballast stone. The impact duration is
therefore a function of the squeeze speed.
Dr Johann Fischer in his thesis, Infl uence of frequency and
amplitude on the stabilisation of track ballast (1983), plotted the
squeeze movement over time on the sine graph. Figure 13 illustrates
how a fast squeezing speed (short time – ti2) will have a longer
impact duration than a slow squeezing speed (ti1).
The rationale is that the faster the squeezing speed, the earlier
during the forward oscillation will the tine start making contact with
the ballast and in so doing remain in contact with the ballast. The
tine has travelled faster through the void space.
The question still remains - what is the required impact duration
to transfer the necessary energy to overcome the inertia of the
ballast stone?
3.6 Squeezing speed and timeThe squeezing speed (closing speed) and duration of the tamping
tines in the ballast also infl uences the durability of the tamping
process. Even though this may not seem important, it is critical to
the process.
To squeeze the ballast into the void, a certain kinetic energy is
required to overcome the inertia of the ballast stone. A minimum
length of time for contact between the tine and the ballast stones
is therefore required to transmit the required energy.
At fi rst one will conclude that energy transmission takes place
during the entire period and squeezing distance of the tine. This
however is incorrect. Due to the vibration-induced forward and
backward movement of the tine which is much faster than the
squeezing speed, energy can only be transmitted during a short
impact period between the tine tip and the ballast face during the
tine’s forward motion.

4. CONCLUSIONScientifi c studies and comparisons between various tamping
techniques have documented the high quality and durability
of the Plasser tamping process. Even in practice the Plasser
tamping process has proven to be thoroughly reliable in countless
operations all over the world since 1953.
High capacity lines throughout the world are serviced using Plasser
machines and the preparation of sections of track for world record
runs was also performed using Plasser tamping machines.
It should however be noted that various other machine
parameters will also infl uence track durability. This includes
the skill and experience of the machine operator, the accuracy
of tamping unit settings, size and condition of the tine tips,
etc. These parameters do not have a scientifi c basis and is
therefore not included herein. However, Plasserail’s skilled and
experienced workforce together with their continuous training
programmes ensures that this is not the weak link in an otherwise
impressively strong chain.
From the fi ndings of a research report of G Kronenberg in 1961,
a guide value for the minimum impact duration of 5 milliseconds
(ms) was established. In this document, this will be taken as a given.
Figure 14 shows that the squeezing speed that will guarantee a
5ms impact duration at 35Hz is 150mm/second.
It can be seen from this graph that at higher tamping frequencies
the ideal impact duration of 5ms cannot be achieved. The ideal
squeezing time can now be derived. Normal squeezing distances
are 120mm.

the ballast bed for a minimum of approximately 1 second which
achieves the minimum required impact time between ballast

The author recently attended the 9th World Congress on Railway Research in Lille, France - a memorable experience in many ways. Much more than railway research alone, it offered a few days in Paris - always a pleasant experience that includes good rail-based public transport. The metro was superb, including a trip on rubber-tyred driverless Line 14, with spacious cars sans end walls, to encourage passengers to spread evenly when trains are crowded.
Comparing the sizes of Paris and Joburg using Microsoft Encarta fi nds both built-up areas to be roughly 30km x 30km. Paris’ population density is much higher, while the aforementioned area excludes outlier destinations such as Disneyland and Charles de Gaulle Airport. Joburg’s area stretches Germiston to Roodepoort, Four Ways to Southern Bypass. The ease with which one can move around Paris and environs by short-appearing journeys, mainly by RATP’s Metro, but also by SNCF’s Réseau Express Régionale (RER) and Transilien, perceptually compacts its true size. Several readers will have experienced this fi rst-hand, but those who have not should seek the exposure. Coordination by autonomous authority Syndicat des transports d’Île-de-France (STIF) is exemplary.
There was also an opportunity to sample Lille Metro, a driverless VAL system—indeed the fi rst such system in the world, which technology has since spread further afi eld. The small profi le vehicles minimise the cost of civil works. Rubber tyres allow rapid acceleration and braking, somewhat above the 0.9 to 1 m/s2 normal passenger comfort limit. Regular passengers get used to it, thus adjusting their comfort limit. The result is cost-effective for small cities that integrate their public transport around a guided rapid transit system.
Refl ections on the CongressThe congress was structured around eight key challenges - a
more and more energy-effi cient railway; an environmentally
friendly railway; increasing freight capacity and services; a world
of services for passengers; bringing the territories closer together
at higher speeds; even more trains even more on time; an even
more competitive and cost-effi cient railway; for an even safer
and more secure railway. Great aspirations for any railway. Or are
they? To participate in these challenges, to be relevant to them,
one must have a railway that actually works. The fundamentals of
positioning railways as worthy corporate citizens in the economies
and societies that they serve are well known. Ineptitude and
recalcitrance seem not to be the stuff of contemporary railway
research: The world of railways has left behind those that do
not work.
Plenary sessions were upbeat, and well they should be. The oral
and poster presentations showed diligent work. Overall, they left
the impression of a gathering of happy railway people that, while
not without problems, appeared to be on top of those they did
have, and enjoyed the continuous improvement that their solutions
provided. Nevertheless, nothing is perfect, and although downside
was not glaringly obvious, it was perceptible. Unsurprisingly for
a conference with a strong European fl avour, freight did not take
the limelight. However, less than 10% of the papers were overtly
freight-oriented. On the whole, the rest were passenger-oriented,
particularly to high speed. Again no surprise, but consider the
following:
The author saw off Railway Corporate Strategy’s operations
manager Fienie Möller and her husband on a TGV from Paris
Gare de Lyon on a Saturday morning. Bearing in mind that TGVs
have progressed from the original single trains, then to coupled
trains, and then again to coupled double-deck trains, not to
mention increased frequency, the throng of people making their
way to the TGVs was at once disorientating and logical. France’s
TGVs, like high-speed trains in other countries, have decimated
or eliminated short-haul air services. Essentially, airports have
now moved into city centres - indeed one of the notions emerging
in the US high-speed awakening. However, the challenge of
handling mass passenger fl ows far in excess of that for which
stations were conceived is a real issue. Gare de Lyon groaned
under the load, and the construction that will one day relieve the
turmoil did not make things easier. Direct high-speed rail access
to city centres is a key attraction, but it does need to align with
reasonable passenger expectations. This is the sort of problem
which railway people are happy to research.

INDUSTRY COMMENT
Dave van der Meulen / Managing Member / Railway Corporate Strategy CC
Report-back From WCRR 2011
The foregoing is salutary for those that contemplate ambitious
freight shifts from road to rail. By the time that rail freight’s market
share dips to around 10%, calls to shift freight from road back to
rail become strident. However, a shift to say 20% of the freight
market, half of what is achieved by North America’s competitive
freight railroads, would then represent a doubling of rail freight,
or even more in a growing market. Railways that have actually
doubled their freight traffi c in a short space of time do not
come readily to mind: Similarly to the success of high-speed rail,
to physically accommodate such a freight shift would require
formidable effort.
Thinking again of Europe, where closely following trucks on
motorways at times give the appearance of trains running on the
roads, concerned stakeholders have envisaged such a shift from
road to rail in research agendas, but it has not materialised. Did
the research that should have supported the shift miss its mark? Or
was it simply not done?
BRICS was represented in neither the organising committee nor
the executive committee of WCRR. Yet its railways convey around
half the world’s rail freight, on a par with the rest of the world
combined. The author has not checked passenger statistics,
but expects a similar outcome. Of 231 papers, only one was by
authors from Brazil, a minuscule representation. If the RICS in
BRICS submitted abstracts, none made the cut. For the record,
the author’s abstract was not accepted. After fi ve papers at
consecutive WCRRs, he arguably knows the ropes. During
preparation of the abstract his wife passed away, so perhaps he
was distracted. On refl ection after the congress, perhaps he missed
the theme. A World Congress? With insignifi cant representation
from developing countries? BRIC railways are doing great things.
We’ll get to the S later.
Brazil shares a colonial railway legacy with South Africa and much
of the rest of Africa. Moreover, it has a medley of track gauges -
both broad and narrow, plus a small amount of standard gauge.
Notwithstanding that handicap, it is implementing a plan to link
its presently isolated northern and southern broad gauge
networks by means of its broad gauge North-South line, ultimately
to support several east-west branches, to develop the interior of
the country.
Russia is liberalising and modernising its railways. Among other
things, it has formed two joint stock companies to exploit the
lion’s share of its freight wagon fl eet; entered into technology
transfer agreements to implement new locomotive technologies;
planned high-speed railways and implemented service on one of
them - Moscow-St Petersburg; raised axle load to 30 tonnes as it
rebuilds its network; acquired US freight wagon technology; and
recognised the strategic requirement to separate high-speed and
heavy freight.
India leads the world in implementing dedicated freight corridors,
to separate growing freight traffi c from its heavy passenger
traffi c, thereby optimising their contending infrastructure
requirements. They will feature double-stacked container trains
hauled by electric locomotives under high catenary, giving the
lie to the pretext that double-stacking and electrifi cation are
incompatible. It is implementing technology transfer arrangements
to acquire modern locomotives, and building contemporary
metro systems on standard gauge separate from its broad gauge
national network, New Delhi being the fi rst.
China’s claim to world railway leadership hardly needs
justifi cation. It is set to be the fi rst country in the world to
concurrently exploit all four of rail’s inherently competitive market
spaces. A world leader in heavy-haul and high-speed on dedicated
freight and passenger lines, metros are advancing rapidly in its
huge cities, and even double stacking has emerged.
Overall, BRIC has made substantial progress in high-level railway
positioning. Surely it has much to share from the research that
underpinned that progress?

Why is this relevant to South Africa?A key take-away from the foregoing
narrative is that South Africa appears to be
grappling with railway issues to which the
rest of the world is insuffi ciently sensitive
to contribute. The author has done much
research on fi tting railways to their settings,
with a view to identifying issues and
seeding solutions. At this time it seems
that what is critical for South Africa
escapes those countries and people that
have revitalised their railways. Are we
therefore beholden to our own insights
and resources? There are quantitative and
qualitative perspectives on this question.
Quantitatively, the number of issues is
simply much higher than that with which
other railway countries have had to deal
concurrently. South Africans of many
persuasions have generated a strong
current of thinking around what the issues
are, what needs to be done, and when,
and how.
Qualitatively, the inherent competitiveness
of South Africa’s railways is not up to the
mark. They are precluded by heritage
from entering or fully exploiting rail’s four
inherently competitive market spaces.
This author has mentioned the underlying
reasons on many occasions, so this is
simply a reminder.
South Africa is now a member of BRICS,
a grouping of world signifi cance in many
respects. Aside from general membership
qualifi cations, well-founded railways were
a BRIC hallmark. Now that the S has been
added, it is time to accelerate revitalisation
of South Africa’s railways, so that it too
can align on this important attribute. We
know what needs to be done. Let’s do it!

happily she is back in service. Class 15F no 3046 Janine competently
took over no 1535’s train operations while she was indisposed.
The club had an unexpected visitor recently in the form of an
inspection by the Rail Safety Regulator (RSR). This followed an
apparently malicious communication suggesting that class 15F
no 3046 was running with no brakes and that the rolling stock
was unroadworthy.
The inspection found no foundation for the claims made but did
ask for stickers warning of overhead wire dangers to be posted
in the locomotive’s tender. According to RSR regulations, these
signs have to be posted on the tender ladder and on the scuttle
plate above the coal gates.
Considering adverse press comment on the RSR in past months,
the fast response to the allegations was commendable.

East African Railways’ class 59 Garratt no 5918 – in steam for Geoff’s
Trains tour in May/June. Photo: T Kautzor.
Steam Tour Down AfricaDuring May and June 2011, United Kingdom operator Geoff
Cooke ran a successful rail tour embracing Kenya, Zimbabwe,
Botswana and South Africa. Not everything came together exactly
as hoped, but participants greatly enjoyed the experience. In
Kenya, class 30 no 3020 ran late on the Naivasha-Nairobi run
owing to cold and viscous fuel oil, necessitating several stops
to brew up, but such stops became unscheduled photo
opportunities. Former East African Railways (EAR) class 24 no
2409, dating back to 1922 and therefore almost 90 years old,
put on a fl awless performance, working to Makadara. Class 59
Garratt no 5918 experienced a few steaming problems so was
late off shed at Nairobi for an afternoon trip along the Mombasa
line. The loco failed just before Embakasi. Both Garratt and train
were returned to Nairobi behind a diesel, arriving back after dark.
Nairobi rail museum’s preserved class 59 locos from the mid
fi fties nos 5918 and 5930 enjoy historical signifi cance, being
Beyer Peacock’s largest ever Garratts for the metre gauge.
Enthusiasts of aged diesel motive power were able to photograph
four remaining old English Electric class 87 units (nos
8720/3/40/1), all sporting today’s Rift Valley Railways’ (RVR)
colour scheme. Despite the occasional glitches, positive reports
were posted on the internet by members of the touring party.
Future rail tours to Kenya will no doubt benefi t from experience
gained by the railway this year.
In Zimbabwe, a new variety of water chemical treatment used by
NRZ staff on their Garratts resulted in excessive boiler foaming
and poor steaming - both on class 15 no 395 and class 16A
no 611. On the southward journey from Thomson Junction, steam
traction had to be abandoned at Lukosi (fortunately following
the best photo opportunities) instead of further down the line at
Dete. The rest of the trip to Bulawayo was handled by a class
DE 6 diesel.
In South Africa, the visitors were hosted at Pretoria by Friends
of The Rail, who lit up class 24 no 3664 for a run to Rooiwal
power station, and also facilitated night photography on shed.
Geoff Cooke remains a good, faithful and very patient tour operator
- year after year – to this part of Africa.
Friends of The Rail, PretoriaThe class 19D 4-8-2 no 2650 was taken out of service recently, to
undergo its three-year inspection.
On behalf of a local photographic club, Gauteng steam
photographer David Benn arranged to have three steam locos lit
up for the members’ outing this winter. The most was made of
photographing Rovos’ class 25NC no 3442 and the Friends’ class
19D no 2650 (its last public steaming currently); also class 24
no 3664.
Atlantic Rail, Cape TownThis group has taken Cape Town by storm with its weekend
leisure runs behind steam along the False Bay coast to Simon’s
Town. The train consists of timber-bodied vintage coaches dating
from between 1922 and 1938, one a lounge car with full bar
service. Class 24 2-8-4 no 3655, the star attraction- built by North
British in Glasgow more than sixty years ago - had eight tubes
replaced recently.
The driving force behind this venture is well-known personality Ian
Pretorius, synonymous a decade ago with Transnet Foundation’s
fondly remembered and highly successful Union Limited safari
operations. Notable among these and popular with both overseas
and local tourists was the regular Golden Thread run from Cape
Town to Oudtshoorn, including a side trip down the scenic
branch across the lakes to Knysna.
Ian, ably assisted by his wife Jenny, organised and personally
managed the Union Limited excursions. Sadly, Jenny died early in
July. She will be missed by the many who came to know her and
who so appreciated the devoted work she put into the enterprise.

and a crew of four. The driver was among those hurt. An estimated
1,500 people were on the Metra train. The conductor broadcast
that there had been a derailment and asked that anyone with
medical training come up to the front of the train. Many of the
passengers climbed out into the “partially lit” tunnel and walked
to the station. Fire crews put down a fi bre-optic rope to help show
the way.
The accident obstructed other trains headed into Union Station,
and buses were brought in to assist.
SUDAN: DEADLY ATTACK ON TRAINOn 26 June, UN peacekeeping mission spokeswoman Hua Jiang
told AFP, “a train transporting southern returnees from Kosti to
Wåu was attacked by Misseriya militia in the area of Meiram,
around 50km south of Muglad.” This was just two weeks before
the region was to celebrate full independence from the north. One
person was killed and four wounded in the raid. Meiram lies in

north Sudan’s state of South Kordofan,
adjacent to Darfur and the tense Abyei
border region. Muglad is the historical
capital of the Misseriya tribe.
According to AFP, “The heavily armed
Arab nomads were a key proxy militia of
Khartoum’s army during its 1983-2005
confl ict with the former southern rebels,
the Sudan People’s Liberation Army
(SPLA). One of the tribe’s chiefs, Omar
al-Ansari, confi rmed the train attack had
happened in a Misseriya area, but denied
that his people were responsible. ‘The train
experienced technical problems in a place
called Hierika, close to South Darfur, and
that was when a group of Darfur rebels
attacked it and grabbed some belongings
from the passengers,’ Ansari told AFP. He
said no one was killed.
“Tensions were running high between
north and south Sudan in the run-up to the
south’s formal declaration of independence
on 9 July, driven by confl ict in the border
areas of Abyei and South Kordofan, and
exacerbated by the lack of progress
in negotiating key unresolved issues.
Northern troops overran Abyei in May in
response to a deadly attack on an army
convoy, prompting more than 100,000
residents to fl ee south, and with the
Misseriya reportedly moving in with
Sudanese soldiers to fi ll the vacuum.”
WESTERN CAPE “TRAIN TRAPS”The realities of driving commuter trains in
Cape Town are spelled out by Janis Kinnear
in the Cape Argus.
“He has watched helplessly from his
cockpit as more than 30 people died on
the tracks in his 30 years as a train driver. ‘
It’s like a car accident, only slower. You can
see you’re going to hit them but even if you
slam on the brakes and blow the hooter,
there’s nothing you can do to stop it.’
“This was the description of only one of
the deaths experienced by the 48-year-
old train driver. With about 300 train
drivers operating in the Western Cape,
he said, the job, once well respected, has
become gruesome and dangerous. He said
damaged fencing and many level crossings
with no booms or warning signals resulted
in people being killed in what he describes
as ‘train traps’.
“The man recalled one of the worst
incidents, which happened just before
Bonteheuwel station, when he watched a
father fail to save his young daughter from
being hit, after they attempted to cross
the tracks with the train bearing down
on them. ‘He tried to pull her back to the
fence but I still bumped the kid. Even if
you don’t get hurt physically, you feel the
impact on your stomach. I missed three
stations, which never happens to me, but
your mind blanks out. The worst part was
that it was a father with his daughter in his
hands. I still remember the bright red jersey
she had on.’

“The majority of incidents occur at level
crossings, he said. Once, the train he was
driving hit three women at once, who all
died on impact. Images of the accident are
still vivid in his mind.
“The driver has refused to operate on the
Muldersvlei and Strand lines, which he
identifi ed as having the most train deaths,
as there was a high number of people
crossing the tracks illegally.
“He said drivers had written letters to
Metrorail management, complaining about
lack of security and warning signals at
level crossings. The drivers had suggested
safety measures to management. These
included installing cameras similar to
speed traps to detect when a pedestrian or
motorist ignores booms, so that the person
caught on camera could be fi ned.
“The man said the country is losing skilled
drivers and technicians and without them
the 2013 target for new trains would be
‘a huge challenge’. He said experienced
drivers were needed to train new drivers
and regular assessments needed to be
done to test their competency levels. ‘Today
they take a guy from the street who gets a
few weeks’ training from a train driver with
only two years’ experience.’
“He started working as a train assistant in
1980 and only qualifi ed as a train driver
seven years later. ‘You used to sit next to
the driver for a few years and then wait for
a vacancy. You had to drive the same train
for about fi ve years.’
“He said operating at night was dangerous,
especially for women train drivers, who put
their lives at risk, often starting as early as
03:00. ‘Imagine if you are a mother with
children, getting up at that time to start a
shift.’
“With only two psychologists assigned to
drivers in the Western Cape, he said drivers
often had to continue working without
counselling, even if they had knocked
down somebody on the tracks and were
traumatised. But he praised a new policy
which insisted train drivers, involved in
accidents be monitored for 72 hours
before being allowed to operate again.
Previously drivers just continued to work.
“Then there’s the issue of drivers fearing
for their lives. In the past you had to bring
the train to a standstill and see if the body
is cleared but nowadays family, and even
passengers, get violent, throwing rocks at
you. There is no protection for you as the
driver.’”
TRAIN STUCK 3 MONTHS IN JAPANESE TUNNELA train that made an emergency stop in
a tunnel moments after the East Japan
earthquake in March remained stranded
there more than three months, while the
operator of the line grappled with the huge
cost of repairing damage caused by the
disaster.
The line, which runs some 36.6km from
Sakari in Ofunato to Kamaishi, remained
closed after the earthquake, as resuming
operations would be extremely expensive -
and possibly beyond the company’s reach.
Level crossings are a nightmare to South African
train drivers. This is the aftermath of a collision
at Buttskop crossing in Blackheath east of Cape
Town, where a minibus driver on the wrong side
of the road overtook a queue of vehicles on 25
August 2010, drove round the lowered barriers
and collided with a Metrorail train, killing ten of
his scholar passengers.

On 10 June, Sanriku Railway workers made their way to the
centre of the 3.9km Kuwadai Tunnel and started the engine of
the single-carriage train for the fi rst time since the disaster.
An operator entered the driver’s cabin and turned on the train’s
internal lights and headlights.
Minoru Yasumiishi, 40, was driving the train, which had been
heading north toward Kamaishi, when it made the emergency
stop. He led two passengers on a 1.5km walk to the tunnel’s south
exit while the rumbling sounds of aftershocks echoed through the
tunnel. “It was the most terrible moment in my life,” Yasumiishi said.
He still dreams about the 30-minute walk to escape the tunnel.
To connect towns in mountainous coastal areas effi ciently, 60%
of the Minami Rias Line runs through tunnels. The line suffered
earthquake damage in a total of 247 locations, including broken
rails and damaged station buildings. Seven drivers who were
assigned to the Minami Rias Line have been transferred to the
Kita Rias Line, which has resumed operations.
To resume all services on its Kita and Minami Rias lines, the
company will need about 18 billion yen. Restoration work on the
Minami Rias Line did not even begin until 1 June.
In an operation dubbed “Sanriku no Kibo” (hope of Sanriku), the
company requested help from Self-Defence Forces personnel to
remove broken rails and debris from station buildings.
The company has also asked for fi nancial aid from the ministry,
but the law currently allows the central government to subsidise
only one-quarter of the company’s post-disaster reconstruction
costs, with the remainder to be covered by the private sector and
local governments.
A senior ministry offi cial said it would be essentially impossible
for Sanriku Railway, a third-sector fi rm that was struggling even
before the quake hit, to shoulder the reconstruction costs on
its own. “We want to support the company, to preserve public
transportation in disaster-hit areas,” the offi cial said.
The ministry has asked the Finance Ministry to allow it to subsidise
about three-quarters of the company’s reconstruction costs. As
for the stranded train, Sanriku Railway planed to complete repairs
to the rails inside the tunnel by late June, and drive the train out
of the tunnel’s south exit.
Because of damage to rails outside the tunnel, the company plans
to take the train only as far as the station at nearby Yoshihama. From
there it is to be transported by road to a railway yard in Ofunato.
Tetsu Yoshida, 47, acting head of operations on the Minami Rias
Line, says, “Even if reconstruction takes a long, long time, and no
matter the cost, we want to reopen our railway lines.”

SURTEES RAIL GROUP
COWS ON THE LINE: 15 TRAINS CANCELLEDFrom RailNews online newsletter:
“Adding a new meaning to ‘cattle class’, cows on the track accounted for 15 train cancellations on a West Midlands’ section of the West Coast line between Nuneaton and Rugby. A spokesman for Network Rail said: “The majority of our rail network runs through rural areas, much of which is farmland. Just as animals are prone to wander across busy roads, they sometimes fi nd their way onto the railway. Our maintenance teams work hard to make sure railway boundaries are safe and secure and to prevent trespassers getting onto the line, whether they have two legs or four.”
Before the disaster, the Minami Rias Line operated 12 round-
trip services a day, and in fi scal 2009 served about 240,000
passengers. It was opened by Sanriku Railway in 1984, and
includes the route that was formerly the Sakari Line of Japanese
National Railways, now defunct.
JAPANESE EXPRESS DERAILSAccording to an Associated Press report, the derailing of one
vehicle caused a six-coach express travelling toward Sapporo to
make an emergency stop inside a tunnel. Smoke entered several
carriages towards the rear of the train. The 240 passengers were
initially told to move to the front three coaches. Eventually they
were evacuated on foot, and more than 30 received treatment
for injuries. Operations head for JR Hokkaido Masayuki Ichijo
apologised saying “Had we made a decision sooner, we could
have evacuated passengers more quickly.”

The single-use crucible reduces the risk of human error. It is made from a bonded refractory material inserted in an easy-to-handle five-litre container. Welds are more consistent. As there is no drying or pre-heating, weld times are much shorter. And the single use crucible is safer and minimises environmental impacts.
GAUTRAIN GAUGEDr J F Slabbert wrote to Moneyweb:“I’m a small private investor and a professional engineer.
“I query your clear enthusiasm for the Gautrain and the PPP model
used. I fully concur passenger rail investment is urgently needed
in SA (especially commuter rail - I use Metrorail every day, not
a pleasant experience!). But the Gautrain has in reality put back
rail transport in Gauteng immeasurably by the employment of
the ‘standard’ (European) gauge despite a specifi c requirement
imposed by cabinet when it approved the Bombela contract that
it be fully integrated with the existing network.
“This choice designed to maximise Bombardier profi ts and justifi ed
on entirely specious grounds of speeds (Google ‘Scheffel Bogie’
for information about speeds attainable on the existing 1,067mm
gauge) is an example of how sophisticated international salesmen
can oversell to South African offi cials with no engineering expertise
(Recall the arms deal).
“The many disadvantages accruing from not using the 1,067 gauge
(besides ending permanently the ideal of travelling from Polokwane
to Cape Town on one train passing seamlessly through Sandton
and on below ground level to Park Station and the Jo’burg CBD,
re-emerging before Soweto and thence to points South), include
duplicated track maintenance equipment, workshops, electrical
equipment, artisan training etc., the impossibility of freight
services, the loss of manufacturing opportunities and many others.
These are not only my own views; Jeremy Cronin in 2007 as chair
of the parliamentary portfolio committee fully concurred with me
(although for undisclosed reasons he took noaction) as did many
others.
“That a similar PPP-type project again using the European gauge
is being sold to Prasa for the Moloto Corridor (as well as an
absurdly unsuitable Durban-Jo’burg high-speed project) is another
step towards the fragmentation of the 25,000km 1,067mm sub-
continental network, the PPP model being a vital tool in the process.
“There is a great deal more that can be said about Gautrain
which as already noted bears a resemblance to the arms deal
contracts. Certainly the taxpayers in both cases are suffering!”

RACEDAY SPECIALS SIXTY YEARS AGOCharlie Lewis reminiscing on sar-L:“This will forever damn me in the eyes of dedicated photographers,
but bioscopes and girls had a lot to do with it. Until the early fi fties,
there ran every Saturday morning from Cape Town to Milnerton
Racecourse a perfect rake of CGR fl at-sided, match-boarded
suburban stock - about seven or eight coaches - with a Belpaire
[class] six in charge. I would see this immaculate train on my way to
town (eightpence for the train fare and eightpence for the bioscope,
just about covered by my pocket
money) in the Coliseum, Plaza
or Alhambra. Whenever I saw
the train I would think ‘must go
out and phot it next Saturday’
but come the day, fl ick and
girls always won out. Then one
Saturday (would have been
sometime in ‘52 or ‘53) the train
didn’t show. That was my fi rst
lesson in getting things while the
going was good”.
