How should a driver respond if the Compressor Fault light illuminates on a 6 car train?

In the context of a 6 car train, if the Compressor Fault light illuminates, the appropriate response is to continue operations and monitor the Main Reservoir (MR) air pressure. This choice is correct because monitoring the air pressure allows the driver to assess the situation dynamically and determine whether the compressor is functioning adequately despite the warning light. It is a prudent first step to ensure the safety of the train and its passengers without immediately resorting to more drastic measures.

Maintaining operations with careful monitoring can provide valuable information about the compressor's performance. It’s possible that the illumination of the fault light may not indicate an immediate catastrophic failure. By keeping an eye on MR air pressure, the driver can ensure that the train continues to operate safely while gathering necessary data to make more informed decisions about subsequent actions.

Other options, such as detaining immediately or shutting down the compressor, might be overly cautious or counterproductive, potentially leading to unnecessary delays without fully understanding the situation. Inspecting all mechanical operations may also be impractical in a real-time operational scenario, as it would divert attention and resources from monitoring the air pressure and could result in a loss of control over the train's operation. Therefore, monitoring the air pressure while continuing operations is the most effective and rational approach
