INTRODUCTION

City not fit to live due to improper town planning

Solution is to provide improved transportaion technology

Present solution: Metro rail, but is it possible in congested area?

Monorail is possible in congested areas.

As name implies : single rail on which train transport system runs

Monorail is unique mass system

It can be put up in any congested area

Provide ease of transportation

Connects arteries and veins of the city.

HISTORY OF MONORAIL

Concept developed since 1800,first monorail in Russia in 1820.

First suspended monorail was demonstrated in 1886 in New

Jersey and are closer in appearance to modern monorail.

Most famous was floating railway in 1901, in Germany.

Floating railway is still in daily use.

Contd…

Gyro monorail: true monorail ,use gyroscopic balancing

system

Due to massive expansion on road and air transport system

after second world war, monorail was the first one to be

abandoned.

But came again into existence due to its eco friendly

characteristics

WORKING PRINCIPLE

Magnetic Levitation (Maglev)

Requires electromagnetic current to generate magnetic field.

Superconducting electric magnets in the vehicle to levitate and

propel the train

CONTD…

An AC is ran through electromagnet coil

Creates a magnetic field that attracts and repels the

superconducting magnets

Revesring the direction of AC: braking.

Varying intensity of AC : speed change

TYPES OF MONORAIL SYSTEM

1) Straddle type 2) Suspended type

CONSTRUCTION

Dig a hole

Drop in a pre-built support pylon,

Truck in the track which was manufactured

offsite,

Lift into place.

MONORAIL IN INDIA

MUMBAI MONORAIL

DELHI MONORAIL

CHENNAI MONORAIL

KERALA MONORAIL

Besides, discussions are going on for Odissa, Bangalore,

Ahemdabad, Pune and other big cities.

DIFFERENCE BETWEEN

MONORAIL AND METRORAILMONORAIL METRORAIL

Rails Single rail Two rails

Construction time B/w 3-4 years Over 5-6 years

Passengers capacity per

hour

10000 40000

Suitability Congested areas having

sharp curve

Open area having no

sharp curve

Average speed 65 km/h 100km/h

Expenditure Rs 120 – 140 crore per

km

Over 200 crore per km

Space occupied Less compared to metro

rail

More compared to

monorail

Cost Rs 8-20 Rs 8 -30

ADVANTAGES

Monorail can be built faster with less cost.

Consumes minimal space.

Ideal mode of transportation for population less then 3 lakh

Serves as Feeder lines for denser cities

Environmental friendly uses no carbon derived fuels

No risk of vehicles getting struck in crossings

Practically silent while travelling

Contributes Greener Environment

Regularly operates at 99.99% reliability.

DISADVANTAGES

To replace a section of track, the entire system needs to be shut down.

The capacity-to-cost ratio is less, even though the per kilometer

construction cost is less.

Cannot run without electricity.

Monorail tracks do not easily accommodate at-grade intersections.

In an emergency, immediate exit is not possible

The biggest disadvantage cited in the case of monorail is its limited

passenger capacity.

FUTURE SCOPE

With the development of monorail and its advantages over

conventional rail system, monorail is the technology for the future.

Monorail will be hitting the rapid construction and operation

replacing the conventional system. Operation of monorail will be

saving the precious fuel. With more research works going on about

the monorail it can be made more advanced and more environmental

friendly.

CONCLUSION

With the increase in the construction technology of Monorail ,it can

reduce the use of city buses in narrow and busy road and will provide

comfort to the passengers because of its suitability in the congested

areas. As it connect the arteries and veins of the city and proves to be

environmental friendly it is going to replace various modes of

transportation which affect environment. With the increase in the

population it is necessary for the advancement of transport

technology in order to provide systematic way of transportation in the

near future; for which monorail can be the best alternative.
