Railway Signalling Descriptive Quiz

General Rules and Subsidiary Rules

• General rules provide overarching regulations applicable in various contexts, while subsidiary rules address specific scenarios or exceptions.

Block Station and Non-Block Station

• Block stations facilitate the stopping and starting of trains, ensuring safe movement through controlled areas.
• Non-block stations do not have dedicated personnel for managing train movements, leading to less stringent controls.

Interlocking

• Interlocking is a safety mechanism used to prevent conflicting train movements through controlled signaling.

Obstruction

• Obstruction refers to any condition or event that delays or prevents the movement of trains along a track section.

Authority to Proceed

• Permission granted to a train driver to proceed past a signal, often under specific conditions.

Block Section

• A block section is a defined segment of track that is controlled to ensure no two trains occupy the section simultaneously.

Distance Signal

• Distance signals indicate to train drivers the status of upcoming signals and facilitate safe traveling over long distances.

IB Signal

• IB signals (Intermediate Block Signals) are placed between two block stations, providing additional safety and control for train movements.

Fog Signal (Detonator)

• A fog signal is a warning device used during low visibility conditions, often activated by the approach of a train to alert the crew.

Calling On Signal

• A calling on signal allows a train to proceed into a block section that is temporarily occupied or in adverse conditions.

Shunt Signal

• Shunt signals direct locomotives and rolling stock to move within yards or rail sidings, facilitating switching and positioning.

Short Notes on Signals

• A thorough understanding of signals is crucial in railway operations for safety and efficient management of train movements.
