When copying mandatory directives via radio, what must the receiving employee do?

When copying mandatory directives via radio, the receiving employee is required to write down the information using the format specified in operating rules. This is essential to ensure accuracy and clarity in communication, especially in a train dispatching context where errors can lead to significant safety risks. Written documentation helps create a reliable record of the directives given, allowing the employee to refer back to the original message and confirm details as needed.

Utilizing the prescribed format also helps maintain consistency across communications, ensuring that everyone involved in the operation interprets the information in the same way. This level of diligence is crucial in fast-paced environments where precision is necessary for safe and efficient railway operations. Consequently, while other options may suggest alternative responses to handling the information, they do not fulfill the procedural requirements that are in place for important communications like mandatory directives.
