How is a train authorized by a timetable schedule designated?

A train authorized by a timetable schedule is designated by both the engine number and the schedule. This dual designation is essential for clarity and precision in train operations. The engine number uniquely identifies the specific locomotive assigned to the train, ensuring that all personnel are aware of which engine is involved in that particular service.

The schedule, on the other hand, provides context regarding the train's assigned route, departure and arrival times, and any scheduled stops along the way. By combining both the engine number and the schedule, railway operations maintain an organized and efficient system that allows for effective communication among team members and adherence to safety protocols.

In contrast, using just the train name or crew name without the engine number would lead to confusion, as multiple trains may share similar names or routes but operate with different locomotives. Therefore, the correct designation method integrates both the engine number and the schedule to ensure safe and coordinated train operations.
