The Abermule disaster happened around noon on 26 January 1921 and was very serious, leading to the deaths of 17 passengers, including Lord Herbert Vane-Tempest, one of the Directors of Cambrian Railways. Owing to a shocking mix-up, involving blatant breaking of the rules by several people and the careless handing of the wrong electric tablet to the driver of one of the trains, a westbound stopping train from Whitchurch and an eastbound express from Aberystwyth collided head on just west of Abermule at a combined speed of more than 60 mph. Signalman Bill Jones, Relief Stationmaster Frank Lewis from Montgomery (who was deputizing Stationmaster John Parry, who was on leave) were principally responsible for the mix-ups, though the crew of the stopping train were at fault in failing properly to examine the electric staff. The accident highlighted the outdated and sloppy way in which some railways were operated on the eve of the Railway Grouping. A general web search will through up more details for those that wish to know more.
