When issuing authority for a track removal, what is required regarding controlled signals?

When issuing authority for a track removal, it is essential for signals to be at STOP. This requirement ensures that all trains and rail staff are aware that the track is not in service and cannot be used. By setting the signals to STOP, it helps prevent any potential accidents or miscommunications that could occur if a train were to inadvertently assume the track is available for use.

A STOP signal acts as a clear and unmistakable indication for engineers and conductors to halt operations on that track, safeguarding both personnel and equipment from the dangers associated with track removal activities. It is a critical safety protocol that aligns with operational procedures designed to prioritize safety during track maintenance or removal scenarios.

In this context, other options do not align with the necessary safety standards. For instance, if signals were at GO, it would indicate that the track is clear for train movements, which conflicts with the reality of the track being removed. Flashing signals might suggest an alert but do not explicitly communicate that the track is out of service. Additionally, unmonitored signals could pose risks since there would be no oversight to ensure that trains are correctly informed about the track status.
