What does a relief crew need to do before departing in Rule 261 single track territory?

A relief crew operating in Rule 261 single track territory must proceed at Restricted Speed before departing. This requirement is essential for maintaining safety as it allows the crew to be prepared for any unforeseen circumstances or hazards that may arise on the track ahead. Restricted Speed means traveling at a speed that allows the crew to stop within half the distance of whatever is observed, ensuring that they can react appropriately to any obstacles or signals ahead.

While checking for yard limits, obtaining a new timetable, and ensuring there is a leaving signal are important practices in railroad operations, they do not directly pertain to the immediate responsibilities of a relief crew in the context of departing from single track territory under Rule 261. Therefore, the emphasis on proceeding at Restricted Speed is crucial for the safety of both the crew and the rail network.
