They are common in the United States. The location of such a device is usually indicated by a blue light. Blue Light Stations provide a direct communication path to the rail system's operations control center and a switch to disconnect traction power from the third rail or overhead catenary in case of emergency. This emergency trip system (ETS) immediately shuts down the traction power supply in the adjacent track section, to protect people already on or about to enter the track from the dangers of electric current. Requirements of Blue Light Stations are defined in the NFPA standard 130, "Standard for Fixed Guideway Transit and Passenger Rail Systems". ==References== 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「Blue Light Station」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.
