Five people were killed and 63 were injured when a derailed TRTA Hibiya Line train was sideswiped by a second train near Naka-Meguro Station. Accident At around 9 a.m. on 8 March 2000, the rearmost car of an eight-car TRTA Hibiya Line (now Tokyo Metro Hibiya Line) train from Kita-Senju x to Kikuna x derailed on the tight curve immediately before Naka-Meguro Station. The derailed car was then hit by the fifth and sixth cars of an eight-car Tobu Railway train travelling in the opposite direction from Naka-Meguro to Takenotsuka x.爆発音と衝撃と突風に襲われて「ガラスの雨を浴びた」…69人死傷「日比谷線」脱線衝突事故から25年 乗客が咄嗟に“土砂崩れ”と勘違いした理由（デイリー新潮） https://news.yahoo.co.jp/articles/8924b5899435f7fb406858ed01eec3ac6ff54d20 https://web.archive.org/web/20250311170000/https://news.yahoo.co.jp/articles/8924b5899435f7fb406858ed01eec3ac6ff54d20 dead March 11, 2025 2025-05-30 Yahoo!ニュース ja Factors It is generally the case that if the distance between tracks is less than the width of the carriages this only allows about 600 mm clearance, so that if a train derails on the same side as the other track, it will almost certainly obstruct the other track, making a collision inevitable. Track circuits detect the presence of a train via electric current passed through the rails, which is shorted by a train car's axle or a physical break in the rails. If a derailment on an adjacent track, that doesn't cause a physical break in the other track, won't cause the track circuit to 'short' resulting in a stop signal. In this situation, a train crew member must either warn railway signal staff of the derailment, stop other trains using a handheld signal, such as a red flag, or manually short the track circuit using a specialized equipment, such as a track circuit operating clip.失敗事例 > 日比谷線の列車脱線衝突 https://www.shippai.org/fkd/cf/CA0000608.html 2025-05-30 www.shippai.org See also List of rail accidents (2000–2009) Similar accidents 1995 Ais Gill rail accident - A 1995 UK railway accident, where a landslide derailed one train across both tracks of a double track route, which was then struck by a train on the other track heading in the opposite direction. Big Bayou Canot rail accident - 1993 USA railway accident, where a train derailed at a bridge struck by a ship. The rails were forced out of alignment, but did not separate, which resulted in the track circuit not indicating a track fault.
