If a train crew is cleared at an interlocking or CP, what exception applies regarding notification?

When a train crew receives clearance at an interlocking or control point (CP), they may proceed without further notification. This is because the clearance given at these locations indicates that they have the authority to move, and the necessary signal aspects and conditions have been met. The established procedures for operations in these areas are designed to streamline the process and enhance safety, allowing train crews to focus on their operation rather than unnecessary communications after clearance is received.

The option regarding canceling a Form D is typically related to situations where the train crew needs to report back to the dispatcher about changes in their movement authority, but that isn’t necessary once they are cleared at an interlocking or CP. The requirement to notify the dispatcher is not applicable in this scenario, as clearance implies that the crew can proceed without needing to re-communicate with dispatch. Finally, confirming their exit is not mandated post-clearance, as the authority to move has already been granted at the interlocking or CP. Hence, the crew can carry on with their duties effectively without additional notifications.
