What should be done if an unintentional brake release occurs?

When an unintentional brake release occurs, the appropriate action to take is to increase the brake pipe reduction by at least 5 psi. This method ensures that sufficient pressure is maintained within the brake system, which is crucial for restoring braking power and ensuring the safety of the train. By increasing the brake pipe reduction, you're effectively re-engaging the brakes, which helps to counteract any potential dangers that may arise from an unintended release, such as increased speed or loss of control.

This strategy is fundamental in maintaining the integrity of the train's braking system and managing situations where the brakes may unexpectedly disengage. Properly reacting to an unintentional brake release through this adjustment enhances the overall safety and operational efficiency within the BNSF rail network.
