Which statement about sidings in non-CTC territory is true?

• A. The authority will specify which siding switch the movement is authorized to or from
• B. The movement may pass without specifying the siding
• C. The siding is automatically included
• D. The siding cannot be used under a Track Authority

Answer: (A)

In non-CTC territory, movements are governed by explicit authority that defines exact routing, including which siding and which switch must be used. The dispatcher’s Track Authority will specify the siding switch that the movement is authorized to operate from or to, providing a clear, protected path and preventing ambiguity about where you may or may not go. That precise specification is why this statement is true.

Think of it this way: without centralized traffic control, you can’t assume any siding is available or automatically included. The authority must name the siding and the switch involved; only then are you authorized to use it. The other options imply automatic or missing authorization, which isn’t how Track Authorities work in non-CTC areas. Sidings can be used under a Track Authority when the authority covers that siding, and the idea that a siding is automatically included or cannot be used under Track Authority doesn’t fit how these protections are issued.
