Which job role is primarily responsible for understanding and adhering to block limit protocols?

The role of understanding and adhering to block limit protocols is primarily the responsibility of the Conductor. Conductors are crucial in ensuring the safe operation of trains, which includes maintaining awareness of the block limits – sections of track that are protected by signals that prevent train movement unless it is safe to proceed. They must ensure that the train does not enter a block that is occupied or unsafe by coordinating communication with Dispatchers and Engineers, and by monitoring the train's movement in relation to the established protocols.

This role includes verifying that all safety measures are followed, which protects both the passengers and the train from accidents or delays. The Conductor’s understanding of these protocols allows them to make informed decisions during the operation of the train, thereby playing a pivotal role in maintaining the overall safety of the transit system.
