Which term is a daily bulletin containing necessary speed restrictions issued by the Train Dispatcher?

• A. General Notice
• B. Schedule
• C. Timetable
• D. Temporary Speed Restriction Bulletin (TSRB)

Answer: (D)

The main concept here is how crews learn about changes to operating speeds that aren’t part of the normal timetable. A daily Temporary Speed Restriction Bulletin is the document that the Train Dispatcher uses to summarize all current speed limits that are temporarily in effect for that day. It lists exactly where the restrictions apply, the new speeds, and the time window or duration for each restriction. This is what the crew checks to know when to slow down and where, ensuring safe, compliant movement through areas impacted by work or other conditions.

General Notices cover broad operational information, not day‑to‑day speed changes. A Schedule or Timetable provides planned train times and routings, not the dynamic speed limits you must observe. The Temporary Speed Restriction Bulletin is specifically designed to convey those temporary speed limits, issued by the Dispatcher, which is why it’s the correct term.
