What must a crew member do with a Track Authority after the train has reported clear of the limits stated on it?

• A. Draw an " X " across each copy and retain until the end of tour duty
• B. Return the copies to the dispatcher for destruction
• C. File the copy for the official record only
• D. Shred the copies immediately

Answer: (A)

After the train has cleared the limits stated on the Track Authority, you cancel it by drawing an X across each copy and retain them until the end of your tour duty. This crossing signals that the authority has been used and is no longer active, while keeping the copies as a traceable record of the movement for safety and regulatory purposes. It preserves documentation of the movement rather than destroying it or shredding it immediately, and it isn’t just filed away for official record later—destroying or returning copies prematurely would remove the essential audit trail.
