An order issued to employees by the General Superintendent-Transportation that may change or annul operating rules, timetable information or special instructions.

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

Answer: (B)

In this setting, the key idea is a General Order—a formal directive issued by the General Superintendent-Transportation that has the authority to change or cancel operating rules, timetable information, or special instructions. That’s exactly what the description describes: an official instruction from leadership that can alter the rules or guidance employees must follow.

General Notices are typically informational and don’t modify the rules or timetable themselves. A Schedule refers to the timetable structure and isn’t an instrument that changes rules. A Temporary Speed Restriction Bulletin (TSRB) communicates specific speed restrictions on portions of the track, not broad changes to rules or timetable information. General Orders are the mechanism used to implement those kinds of official changes or suspensions.
