翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Trainphone ： ウィキペディア英語版 Trainphone Trainphone was the Pennsylvania Railroad's system for voice communication between train crews on moving trains and with dispatchers, tower operators and similar. It was also used by the Kansas City Southern, and to some lesser extent on the Duluth, Missabe & Iron Range. It did not use radio, but rather electromagnetic induction. Railroads did not own any radio frequencies at the time, and the PRR's busy network found the previous methods (passing a physical paper message, or requiring a train to stop to pick up orders) insufficient. The trainphone system was first trialled in 1936 and perfected by 1943. ==Equipment== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trainphone」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
