Answer: When snow is up to or above the top of the rail
Feedback:
Performing a running air brake test during winter weather keeps the ice and snow from building up on the braking components. It is vital to ensure brakes are functioning properly and free of debris, particularly when icy rail conditions create additional challenges to braking safely.
