What should a train do if it needs to pick up a crew member without entering yard limits?

In situations where a train needs to pick up a crew member without entering yard limits, it is essential to first wait for clearance from the dispatcher. The dispatcher is responsible for coordinating train movements and ensuring safety throughout the system. This communication allows the dispatcher to confirm that it is safe for the train to proceed with its plans without interfering with other train operations or violating any signals.

Clearing this type of movement with the dispatcher helps maintain overall operational efficiency and safety, as the dispatcher may have other trains in the vicinity or operational constraints that the crew may not be aware of. Thus, obtaining clearance ensures that all necessary precautions and protocols are followed before proceeding.
