What must an employee provide if using a track car on a radio call?

When an employee is using a track car on a radio call, it is essential to provide "TC" followed by the number of the car. This designation is crucial for clear communication and identification purposes within the operating environment. By using the "TC" prefix, it is quickly understood by other rail personnel that the communication pertains to a track car, thereby minimizing any potential confusion with other types of rolling stock or operations.

The practice of standardizing communication with specific terminology helps maintain safety and efficiency, ensuring that everyone involved is on the same page regarding which vehicle is being referenced. Given that track cars can serve various operational needs, such as maintenance or inspections, clear identification is vital for situational awareness among crew members and dispatchers.
