In this fast paced world with
spectacular advances in science and technology, need for innovative systems for
transportation is vital. This project gives a solution for transport of men and
materials with less effort and energy between the railway platforms.
The system uses a rack and pinion
arrangement actuated by reversible motors to extend and retract the slab that
is placed between two platforms. Hand rails and balustrades are provided and a
roof is fixed over the slab. A microprocessor unit controls the motor based on
the train signaling device.
As the signaling device shows green,
means that the train is in-station, so the motor is not actuated and remains
slab remains in the retracted position. As the signaling device shows red the
slab is extended to bridge the platforms, once the slab touches the other
platform the gate opens. These gates are stationed between the doors of the
train so it does not interfere with the passage of the train compartment door. As
the signaling device turns yellow the slab is retracted.
