Which document serves as the authority for the movement of regular trains?

The timetable serves as the primary authority for the movement of regular trains. It outlines the schedule, including departure and arrival times, as well as information on train order, stops, and any special instructions that are relevant for train operations. The timetable ensures that trains operate in an organized manner, allowing for efficient scheduling and coordination on the tracks.

Understanding the relevance of the timetable is critical for ensuring safe and punctual operations, as it dictates how trains interact with each other, manage their speed, and adhere to designated routes. It is tailored to provide all necessary operational guidelines that train crews must follow, thus serving as a foundational document for day-to-day operations in the railroad system. In contrast, the other documents mentioned, such as Form L, Clearance Card Form A, and Blue Signals, serve different purposes and do not provide the overall scheduling authority that the timetable does.
