Running Brake Test Procedure 14.13 Running brake test procedure:
The test must be made as soon as the speed of the train is sufficient to prevent stalling. While using sufficient power to keep the train stretched, apply the train brakes with enough force to slow the train, give one short sound of the whistle, and ascertain whether or not the train brakes are operating properly. The locomotive brakes must be kept released during the running test. If the train brakes are operating properly, the train brakes may be released, giving two short sounds of the whistle, and the train may proceed. The train crew is jointly responsible with the engine crew to know that the running test has been made. If the train brakes are not operating properly, the train must be stopped, an inspection made to determine the cause, and the trouble corrected. Before proceeding, an application and release test must be made. Immediately upon proceeding, a running test must be repeated.
