Abstract
A method and structure for automatically stopping a train riding on a railroad track should at least one wheel of the train go off of the track. The train has a conventional pneumatic brake line, with which a cutting arrangement is operatively associated for actuation should one wheel of the train go off the track, the severing of the pneumatic brake line allowing release of air so as to gradually apply the brakes and ultimately stop the train.
