. It highlighted several safety problems, including wheel design, braking and communications along trains. The accident came in a decade which saw many terrible accidents on the rail network, and culminated in the Tay Rail Bridge disaster of 1879.

Causes

The basic cause was established as a broken tyre on the carriage just behind the locomotive, but that failure was worsened by the poor braking system fitted to the train. When a passenger warned the driver of the problem, by waving from the carriage window, it was still being pulled along intact along the rails. However, the driver braked immediately, before the brake at the rear of the train in the guards van could be applied. The engine brake caused the failed carriage to be squashed, and the carriages behind derailed near the Oxford Canal

. There were 34 deaths and 69 seriously injured in the carriages which fell from the bridge over the canal.

Investigation

The investigation which followed established the root causes very quickly. The tyre was on an old carriage, and was of an obsolete design. The fracture started at a rivet hole, possibly by metal fatigue

, although it was not recognised as such by the inquiry. The weather was very cold that day, with snow blanketing the fields and very low freezing temperatures, another factor which hastened the tyre failure. The disaster led to a reappraisal of braking methods and systems, and eventual adoption of continuous automatic brakes being fitted to trains, based either on the Westinghouse air brake or a vacuum brake
Vacuum brake

A variant, the automatic vacuum brake system, became almost universal in British train equipment and in those countries influenced by British practice.

. The Railway Inspectorate recommended Mansell wheels, a type of wooden composite wheel, be adopted by the railway companies since the design had a better safety record than the alternatives. There had been a long history of failed wheels involved in serious accidents, especially in the previous decade. The problems of broken wheels was not resolved until cast steel mononbloc wheels were introduced. The Inpectorate were also critical of the communication method between the locomotive and the rest of the train using an external cord and gong, suggesting that a telegraphic method be adopted instead.
