What is the procedure called to release locomotive brakes during an automatic brake application?

The procedure used to release locomotive brakes during an automatic brake application is known as actuating. This term specifically refers to the action of causing a mechanical or electronic system to operate. In the context of locomotive operation, actuating the brakes means engaging the systems that will enable the brakes to release, allowing the train to move freely again after an automatic application has occurred.

In train handling, understanding the concept of actuating the brakes is crucial because it highlights the importance of the timely and correct operation of the braking system. This ensures safe and efficient train movement, especially when transitioning between different phases of operation, such as moving from a stopped position back to a running state. Familiarity with this term and procedure helps ensure that engineers and conductors effectively manage the train's operation.
