Which term describes the authority for the movement of regular trains subject to the rules, including movement instructions and schedules?

• A. Timetable
• B. Schedule
• C. Main Track
• D. General Order

Answer: (A)

The key idea here is that the timetable is the official authority controlling how regular trains move. It isn’t just a schedule of when trains run; it’s the published document that sets the rules, identifies routes, assigns train numbers, and includes movement instructions crews must follow. That combination—rules plus times and routing—constitutes the formal authority for train movements.

A schedule alone is simply the list of times trains are due to run, without the broader movement rules. A general order contains specific instructions to employees but isn’t the routine authority that governs daily train movements. The main track is the physical track itself, not an authority document.
