The derailment of a passenger train at Lytham, Lancashire, England occurred when the front tyre of the locomotive fractured and led to the loss of 15 lives. The accident happened on 3 November 1924 to the 4.40 pm Liverpool express travelling to Blackpool at 5.46 pm. When the tyre failed, the train was moving at about 50 mph (80 km/h), and the train derailed at a crossing, then hit a bridge, closely followed by the Warton signal box. The building was completely demolished and coals from the grate ignited a carriage. The engine toppled over together with two of the carriages.
