What does the train dispatcher/operations supervisor need to issue if a dimensional car is set out on an adjacent track?

The train dispatcher or operations supervisor must issue a track bulletin when a dimensional car is set out on an adjacent track. This action serves a critical purpose in ensuring safety and operational clarity. A track bulletin provides necessary information regarding the status of the tracks, including details about unexpected conditions or obstructions that could impact train movements.

In the case of a dimensional car, its presence on an adjacent track could affect the clearance or operations for trains that pass by. The track bulletin alerts train crews and other personnel of this presence, helping them to take appropriate precautions and avoid potential accidents. This communication is essential for maintaining safe train operations and ensuring that all involved parties are aware of the conditions they are facing.

Other options, while they could be relevant in different scenarios, do not specifically address the need to communicate the presence of the dimensional car on an adjacent track in the same immediate way that a track bulletin does. Thus, issuing a track bulletin is the accurate and appropriate action in this situation.
