When should a train operator notify maintenance regarding wheel flats?

A train operator should notify maintenance regarding wheel flats immediately after inspection because this prompt reporting is crucial for safety and system integrity. Wheel flats can lead to increased wear on the rail and can affect train performance, making it essential for maintenance crews to address the issue without delay. Immediate notification allows for timely inspection and repair, preventing further damage and ensuring the continued safety of operations.

Delaying the report until after the train completes its route, for example, could result in more severe consequences, such as further degradation of the wheels or potentially unsafe operating conditions for subsequent trains. Thus, reporting right after inspection is a best practice that aligns with proactive maintenance and safety protocols in the rail industry.
