Railways use significant human labour for inspections
Human inspectors still perform majority of visual
track testing by walking the track.
An average inspector covers less than 3 kms of
track testing in one day.
Automation of manual inspection processes is
important for better quality inspections and
measurements as sensors cover more track,
more quickly and provide objective data.
On highly frequented tracks, wear would justify
more inspection but often, there are not enough
slots to do it.
Or expensive measuring vehicles are used,
which are operated outside normal railway
operating hours.
Z series is a sub-ambient cooled singular assembly with integrated
processing, electronics, sensors, lighting and data storage. It scans rail and track bed.

Z series high res images detect defects early
Rail Vision cameras image track at 0.5mm per pixel or less producing some of
the best quality imagery and measurements, and detect faults early when they
can be repaired at a lower cost.

Vegetation maps
S Series
The detection of vegetation and the measurement of its
clearance is an important S series output. Colour
cameras combined with LIDAR measurements
automatically determine the amount, type and extent of
vegetation growth surrounding railway tracks.
Vegetation maps
S Series
Clearance measurements are reported with track location based on vegetation proximity to the track centreline. Areas in red need to be cut back from the track.
Vegetation maps
S Series
Vegetation maps are generated from measured data to show the extent of various types of vegetation on the track. The position of hazardous trees is shown. The maps are interactive.
Sighting distances
S SeriesS Series equipment makes
sighting measurements for
signals, level crossings and
speed signs. There are strict
rules on what these minimal
distances must be to allow
the driver to brake if
needed.
Automated recognition of
signals, level crossings and
speed signs, is followed by
calculation of their sighting
distances from sensors with
less than 1 meter accuracy.
All signals/ level crossings
and speed signs not
meeting sighting criteria are
highlighted with track
curvature data.
