Authorized train speed applies to which portion unless otherwise specified?

Authorized train speed applies to which portion unless otherwise specified?

• A. The locomotive only
• B. The passenger cars only
• C. The entire train
• D. The caboose only

Answer: (C)

Authorized train speed is the maximum speed the train may travel on a given route, and it governs the entire train as a unit unless a specific instruction says otherwise. The locomotive provides the power, but all cars—the locomotive, passenger cars, and any other equipment—must remain under that speed. If a portion of the route or a particular car has a different limit, that would be stated in the timetable or authority. So, in standard operation, the speed applies to the whole train, not just one part.
