What must an employee identify when initiating a radio call?

When initiating a radio call, it is essential for an employee to identify both the employing railroad and the base station. This ensures clear communication and proper identification of the parties involved in the call. By naming the employing railroad, the employee establishes which company is being represented, which is crucial for accountability and operational clarity, especially in environments where multiple railroads may be operating in close proximity. Identifying the base station further narrows down the specific communication point, allowing receivers of the call to understand the exact context and relevance of the message being conveyed.

In contrast, identifying only the schedule number, mobile radio unit, or just the individual’s name would not provide sufficient information for other parties to understand who is communicating and their affiliation. This could lead to confusion or miscommunication, which can have safety implications in the context of railroad operations, where precise communication is critical.
