The Southall rail crash occurred on 19 September 1997, on the Great Western Main Line at Southall, West London. An InterCity 125 high speed passenger train (HST) failed to slow down in response to warning signals and collided with a freight train crossing its path, causing seven deaths and 139 injuries. Great Western Trains, whose managing director survived the crash in one of the most badly affected carriages, was fined for failure to ensure that the HST had their automatic warning system working during long journeys.
