Written instructions issued by Rail Operations Management containing temporary instructions or modifications to the rules for a defined period.

• A. General Notice
• B. Temporary Directive
• C. Cab Signal
• D. Strobe

Answer: (A)

A General Notice is the formal written notice issued by Rail Operations Management that communicates temporary instructions or modifications to the rules for a defined period. This type of document is designed to inform a broad audience—crews, stations, or departments—about temporary changes, such as short-term procedures, work rules, or adjustments to standard operating practices, for a specified timeframe. It sits apart from equipment terms like Cab Signal or Strobe, which refer to devices rather than communications. While a term like Temporary Directive could describe temporary instructions, the standard and most appropriate term for this broad, time-limited policy communication is General Notice.
