All "Air Brakes" are designed so if there is a failure in the compressed air line, the brakes automatically apply. This is true on over the road trucks and on trains. This is a safety feature, so that vehicles will not move, if the brakes cannot be successfully released. shutting down the locomotive engine in Canadian crude oil accident did not cause the brakes to fail. Someone had to release the brakes, since no compressed air in the brake lines would automatically turn the brakes on. Air brakes are spring powered on, and air pressure pushes them off.
