語呂合わせ依頼者より What sort of music do you like? http://levitra.in.net/ levitra 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. by Wilburさん
