All transmission must be repeated by the employee receiving them except?

• A. Used in yard switching operations
• B. Those transmissions that do not contain any information, instruction or advice that could affect safety of railroad operation
• C. Messages containing routing instructions
• D. Emergency transmissions

Answer: (A)

In NORAC procedures, transmitting information is repeated back by the receiver to be sure the message was understood and to prevent miscommunication that could affect safety. The exception to this rule is in yard switching operations: within yards, routine switching directions are issued in a fast-paced, low-risk context, so the requirement to repeat every transmission is relaxed to keep operations moving smoothly. So, for yard switching operations, you don’t have to repeat the message back; you acknowledge or act on it as directed. In contrast, messages that involve routing instructions or emergencies are safety-critical and must be repeated to ensure the caller and responder share the exact understanding and can take appropriate action.
