What should a driver do if the Compressor Fault light does not reset?

In situations where the Compressor Fault light does not reset, the most appropriate action is to submit a TMM (Technical Maintenance Message). This is essential because the persistent fault indication suggests a potential malfunction in the compressor system that could lead to further operational issues or safety hazards. By submitting a TMM, the driver ensures that maintenance personnel are alerted to the problem and can assess it properly.

Choosing to continue operating can compromise safety, as the proper functioning of the compressor is crucial for the overall performance and safety of the train. Similarly, detaining passengers, while potentially safe in this context, does not provide a resolution to the underlying issue and may cause unnecessary delays without a plan for remediation. Shutting down the train could also be considered if immediate action were required, but submitting a TMM provides a measured response, allowing for proper review and action to be taken without stopping operations unnecessarily. Therefore, submitting the TMM is the best course of action for addressing the fault efficiently while ensuring safety and operational integrity.
