How should a conductor react to a signal indicating a stop?

A conductor's primary responsibility is to ensure the safety and efficiency of train operations. When encountering a signal that indicates a stop, the correct reaction is to immediately inform the engineer and prepare the train to stop. This action is critical because the signal is conveying crucial information regarding track conditions, potential hazards, or operational instructions.

By promptly informing the engineer, the conductor facilitates a coordinated response to the signal. This not only aids in adhering to safety protocols but also ensures that all crew members are aware of the situation, allowing preparations to be made for stopping the train safely and in a controlled manner.

The necessity of this action is underscored by the importance of following signals, which are fundamental to maintaining safe train operations. Ignoring or misinterpreting these signals could lead to dangerous situations, hence the conductor's immediate reaction to stop is paramount.
