Claim: The 1991 Japanese Shigaraki train disaster (the deadliest Japanese train crash between 1963 and 2005) happened on the SKR Shigaraki Line when a train from Kyoto collided with a JR West train at the Onotani Signal Station, the only place where two trains should have been able to safely pass.
Evidence: The Shigaraki train disaster (信楽高原鐵道衝突事故, Shigaraki Kōgen Tetsudō shōtotsu jiko) was a railway accident that occurred in Shigaraki (now Koka), Shiga Prefecture, Japan on May 14, 1991. 
Until the Amagasaki rail crash in 2005, this was the deadliest railway disaster in Japan since the Yokohama rail crash of 1963, which killed 161 people. 
A Shigaraki Kōgen Railway (SKR) train and a West Japan Railway Company (JR West) train collided head-on, killing 42 people and injuring 614 others. The Onotani Signal Station (小野谷信号場, Onotani Shingōjō) was the only point on the single-track line where two trains can safely pass, but the JR West train had already gone past that signal station, as it was given a green signal despite the approaching SKR train.
