If the communicating signal becomes inoperative, how can the train proceed?

The correct approach for a train to proceed when the communicating signal becomes inoperative is for the conductor and engineer to reach a proper understanding. This is essential because clear communication and coordination between the two roles ensure that both parties are aware of the train's status and any necessary actions to take. Since the signal is inoperative, relying on alternative methods of communication, such as a mutual understanding, is crucial for maintaining safety and operational integrity.

In scenarios where communication devices fail, it is vital that the crew operates as a cohesive unit, sharing vital information and confirming intentions before taking further action. This collaboration minimizes the risk of misunderstanding and allows for safe movement in potentially hazardous situations. Therefore, establishing a clear understanding is the appropriate protocol when standard communication signals are not available.
