A train operator receives a request from the assistant dispatcher to whistle for the signal maintainer. What should the train operator do?

When a train operator receives a request from the assistant dispatcher to whistle for the signal maintainer, the appropriate action is to acknowledge and carry out the request. This is crucial for ensuring safety and effective communication within train operations. Whistling for the signal maintainer serves as a notification that help is needed and alerts the maintainer to the train's presence. By responding promptly, the operator helps facilitate any necessary maintenance or repairs, maintains operational efficiency, and follows established protocols.

Communication among dispatchers, train operators, and maintenance personnel is critical for the safety and coordination of train services. Following directives from the assistant dispatcher fosters teamwork and adherence to operational procedures.
