電磁自動ブレーキを使用する貨物列車の組成時のブレーキ指令線の導通確認検査時に，もし断線が発見された場合には，断線箇所の特定に数時間を要する場合があり，ダイヤ遅延や最悪の場合には運休となる。本開発では，断線時の迅速な復旧支援を行うため，編成貨車の端から指令線の断線箇所を特定できる電気回路網理論に基づいた断線箇所特定アルゴリズムを提案した。%The inspections after making up a freight train includes checking the normal connection status of the train line used for applying automatic electromagnetic air brake. In case any disconnection is detected, it takes several hours to find the location of the breakage point. Therefore, we developed an algorithm using circuit analysis to make it possible to detect and locate the fault in the line from one end of the train, and fabricated a portable type device and a on-locomotive type one incorporating the algorithm. In actual tests using the new system on a freight train, train line faults were detected up to the 20th wagon. This system was capable of locating a failure in approximately 30 seconds.
