When a conductor is backing up a train to a derail, what is required?

When a conductor is backing up a train to a derail, making a safety stop two car lengths from the obstruction is essential to ensure safety. This distance allows for an appropriate buffer zone that helps the conductor assess the situation ahead. By stopping at this distance, the conductor can prevent any potential accidents or damage to the train or the track infrastructure.

Establishing this safety stop ensures that the crew can visually confirm that the train is safely positioned without risk of colliding with the derail or any nearby obstruction. It's a critical practice within operating rules that prioritizes safety and operational integrity when handling moves around potentially hazardous situations like derails. This procedure reflects a proactive approach to safety, mitigating risks associated with backing operations.
