In relay or hostler service, what should crewmembers carry instead of timetables and NORAC rules?

• A. The Operating Rules and Timetable
• B. Bulletin Orders and other pertinent information, which may affect their duties
• C. No documents
• D. A phone

Answer: (B)

In relay or hostler service, crews face dynamic working conditions in yards and during switching, so they rely on current instructions that can change quickly. Bulletin Orders provide the up-to-date guidance specific to the crew’s duties, including temporary rule changes, special instructions, or information about track conditions and capabilities. These bulletins are issued to reflect what’s actually in effect for that day or shift, and they can modify or augment NORAC rules and the timetable so workers aren’t operating on outdated information. Carrying Bulletin Orders and other pertinent information ensures safety and proper authority for every move, since static timetables or the rules alone may not cover the latest conditions.

Carrying only the timetable and NORAC rules wouldn’t guarantee awareness of recent adjustments or instructions tailored to yard operations. A phone isn’t a reliable substitute for official, written directives that govern how to proceed in specific situations, so it’s not the right source of operational guidance for these tasks.
