What action is required when a train stops to allow another train to pass?

When a train stops to allow another train to pass, it is important to ensure safety while also maintaining proper signaling practices. The correct action in this scenario is to leave the headlight on dim. This serves two purposes: it helps maintain visibility for the passing train, and it indicates to the train that is stopping that it is stationary and prepared to allow the other train to proceed.

When a train is stopped and the headlight is switched off, it can create confusion for the approaching train, which might not realize that the train is parked. Additionally, keeping the headlight on dim prevents unnecessary glare, allowing for better visibility in conditions where the passing train could be close and could inadvertently become distracted or blinded by a bright light.

Maintaining the headlight on dim is a standard practice to ensure clear communication and safety between trains on the same track in close proximity. This action aligns with operational protocols that prioritize the safety of all equipment and personnel involved.
