Lytham rail crash

The derailment of a passenger train at Lytham, Lancs occurred when the front tyre of the locomotive fractured and led to the loss of 14 lives. The accident happened on November 3rd, 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 convert|50|mi/h|km/h|abbr=on, 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.

Investigation

Colonel Pringle of the Railway Inspectorate found part of the broken tyre convert|50|yd away in a field, the left-hand leading wheel of the engine having broken. The tread had broken from a large internal blow hole. The defect probably formed during the steel casting operation, and became critical as the tread was worn away. The tyre had been made n 1920, and had run over convert|100000|mi|km before failure. All the other wheels from the same batch were removed from service and broken up, but without finding any cavities in the treads. Pringle also showed how tyre fractures had decreased over the years. In 1880, there were 1238 broken tyres, 577 ten years later and by 1900, the number had dropped to 234. The majority were found on wagons, but by 1920, there were only 20 wheel failures. The drop in failure rate was due to the introduction of the monobloc steel wheel and better inspection and maintenance methods.
