What is a Block Limit in railway terms?

A Block Limit in railway terminology refers specifically to a place where a block limit signal is displayed. This signal indicates the boundaries of a block section on the track, which is crucial for the safe and efficient operation of train movements. Block limits define the sections of track that can be occupied by trains and help to ensure that only one train operates within that section at a time, thus preventing collisions and ensuring safe spacing between trains.

The significance of the block limit signal lies in its function as a safety measure that communicates essential information to train operators. It helps them determine when it's safe to enter or exit a block, directly influencing their operation and adherence to schedules. This signal is a vital component of the signaling system that maintains order and safety in rail operations. Understanding how block limits work is fundamental for anyone involved in railway operations, particularly for roles focused on train control and movement management.
