4. INTRODUCTION
providing improved transportation technique.
Ease and safe transportation, without loss of time.
Monorails runs on single rail as against metro rail.
It can be put up in any congested area
Monorail is possible in congested areas.
Connects arteries and veins of the city.
The traffic is increasing day by day , which is making city not fit to live .
5. WHY MONORAIL ?
Intermediate capacity guided urban transit system
Requires less space / footprint
System uses 0.80m wide beam to guide the train
Allow Steeper Gradients & Negotiates Sharp Curves
Derailment proof
Feeder service to Metro and Suburban systems
Faster transit connectivity
6. HISTORY OF MONO RAIL
Gyro Monorail in 1909
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.
7. Floating railway is still in daily use.
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.
8. WORKING PRINCIPLE
Magnetic Levitation (Maglev)
Requires electromagnetic current to
generate magnetic field.
Superconducting electric magnets in the
vehicle to levitate and propel the train
9. An AC is ran through electromagnet coil
Creates a magnetic field that attracts and
repels the superconducting magnets
Reversing the direction of AC: braking.
Varying intensity of AC : speed change
10. TYPES OF MONORAIL SYSTEM
Monorails are classified into two
Straddle type and
Suspended type Monorail System
Since the Straddle-type travels by straddling the track, its center of
gravity is situated above the track.
The Suspended-type on the other hand, is configured suspending from
the track, with its center of gravity under the track.
13. TECHNICAL ASPECTS
POWER
Almost all modern monorails
are powered by electric motors.
contact wires or electrified
channels attached to or enclosed
in their guidance beams, but
diesel-powered monorail
systems also exist.
16. SWITCHING
monorails are capable of more efficient
switching than in the past. With suspended
monorails, switching may be accomplished
by moving flanges inside the beam way to
shift trains to one line or another

20. DISADVANTAGES
To replace a section of track, the entire system needs to be shut down.
The capacity-to-cost ratio is less
Cannot run without electricity.
Immediate exit is not possible
Limited passenger capacity
25. 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.
