Isabella:
Whereabouts are you from? <a href=" http://www.sniderscyclery.com/?erectosil-erfahrungen.pdf#fantasy ">erectosil 100 mg</a> Alton Bob- you are correct. Air is used to RELEASE the brakes on a train, not to engage them. Thus, a locomotive shutting down would have ensure that the train could not move. Compressed air would have had to have been pumped into the train-line to release the brakes and the only way that I know for that to happen is for someone to open the brake valve.
