Who closes out the TMR?

• A. Final MCT
• B. Origin MCT
• C. Rail Carrier
• D. Rail Supervisor

Answer: (B)

The important idea here is who owns and finalizes the record of a train’s movement from its starting point. The TMR is the official log of that movement, and the person or unit at the origin is responsible for closing it out. The Origin MCT handles all origin-side data and checks—things like ensuring the train is properly documented and ready to depart. When those origin tasks are complete, they close the TMR to lock in the origin portion of the record and hand the movement forward. The Final MCT would come into play later to close out the record at the destination, while the rail carrier and rail supervisor oversee operations but don’t perform the official closure of this origin-focused log.
