Which document must employees have with them while on duty?

• A. Air Brake Instructions (TRO-4)
• B. Safety Rules for their Department (TRO-5)
• C. The Operating Rules and Timetable (TRO-1 and GO)
• D. None of the above

Answer: (C)

The key requirement is to have the official operating reference that governs day-to-day train movement and crew duties: The Operating Rules and Timetable. This document combination provides the rules you must follow and the timetable that shows where and when trains operate, what you’re authorized to do, and how to interpret signals and protections. Having it on duty ensures you can verify procedures and authority right when you need them. Air Brake Instructions and Safety Rules are important resources, but they aren’t the document you’re required to carry as your on-duty reference. The Operating Rules and Timetable (often with General Orders) is the authoritative portable reference for everyday operations, which is why it’s the best answer.
