Answer 1

Concept:

In railways, the disc signals are provided for the purpose of shunting.

When the red band of the disc is in a horizontal position, it indicates “STOP”.
When the red band of the disc is in an inclined position, it indicates “PROCEED” slowly for shunting.

The indications of a disc signal are depicted in the following diagram:

Disc Signals/Shunting Signals:

The disc signals are in the form of a circular disc with a red band on a white background and these discs can rotate in a vertical plane. By rotating the disc different operations are instructed.
In railways, disc signals are used to instruct various operations like changing the locomotive of a train, attaching/detaching of wagons, changing the order of wagons, etc. These kinds of operations are collectively known as shunting or shunt moves.
