The '''Audenshaw Junction rail accident''' occurred on the evening of 20 May 1970 near [[Guide Bridge railway station]], [[Greater Manchester]], [[England]]. A [[British Rail Class 506|Class 506]] [[electric multiple unit]] train from [[Manchester Piccadilly]] to [[Hadfield, Derbyshire|Hadfield]] had started away from a signal when a [[railroad switch|set of points]] moved underneath the train, causing it to be derailed and throwing the centre carriage onto its side. Two passengers were killed and 13 were injured. |
|||
==Investigation== |
|||
The investigation found that the [[signalman (rail)|signalman]] at Stockport Junction [[signal box]] was at fault. |
|||
The [[lever frame]] at Stockport Junction was equipped with [[electro-pneumatic]] slides instead of levers, with electrical economising contacts located above them. The signalman wanted to cross a freight train travelling in the opposite direction behind the passenger train, but the points were locked by a [[track circuit]] until the passenger train was well clear of them. |
|||
In order to defeat the [[interlocking]] and speed things up, he had pulled the points slide slightly out of the frame. This action held the protecting signal at red as a safety measure, so in order to clear it, he obtained a false feed between two of the economiser contacts, most likely using a [[Bardic lamp]] or a broken [[hinge]] that was subsequently found. It was likely that he then accidentally inched the points slide too far, and they moved under the train. |
|||
False-feeding was apparently common knowledge between signalmen in the 10 similar signal boxes in the area, and the frames were subsequently boxed in. |
