What is the correct action to take when penalty brake application occurs?

When a penalty brake application occurs, the appropriate action is to move the Automatic Brake Valve (ABV) handle to the RELEASE position and note that the Penalty Control System (PCS) resets. This approach is essential because it effectively disengages the penalty brake application, allowing for normal operations to resume. The removal of the penalty application needs to be done carefully to ensure that the brakes are not inadvertently applied or left in a state that could lead to another issue.

This action aligns with proper train handling procedures and promotes safety by ensuring that the brakes can be managed effectively without unnecessary complications. Recognizing the reset of the PCS is also crucial, as it indicates that the system is returning to its normal operating parameters.

Other actions may lead to unsafe conditions or prolonged disruptions in service. For example, moving the ABV handle to REVERSE could create confusion and potentially lead to further complications with braking, while applying emergency brakes could unnecessarily escalate the situation. Leaving the ABV handle in its current position would fail to address the penalty brake application, prolonging the issue. Thus, moving the ABV handle to RELEASE is the correct and safe practice.
