For train H-CHIDEN9-05, if the scheduled HPT is 2.0 and the actual HPT is 2.2, what action is needed to comply with regulations?

The scheduled HPT (Handling Power Torque) of 2.0 indicates the maximum allowable performance level for train H-CHIDEN9-05. When the actual HPT is recorded at 2.2, it exceeds the scheduled limit, which raises concerns over compliance with regulations regarding train handling and safety.

To comply with the regulations, isolating units to bring the HPT down to or below the scheduled limit of 2.0 is necessary. This action ensures that the train operates within safe handling parameters, reducing the risk of equipment stress, potential safety hazards, and ensuring adherence to company and federal guidelines.

Maintaining the actual HPT at 2.2 or allowing it to rise further could lead to compliance issues, increased wear and tear on equipment, and possibly dangerous operating conditions. Hence, taking action to isolate units effectively limits the HPT to an acceptable level, ensuring both regulatory compliance and the safety of operations.
