The train, travelling at 75 mile/h, became derailed at a broken rail. A piece had broken away from the head of the six-foot rail at the running-on end. The rail had also broken completely about 8 in. from the end. All eight keys for four sleepers on the approach side of the joint, and the cess rail keys for the first four sleepers beyond the joint, were out and lying beside their chairs. Examination of the broken rail stated that the 95 lb/yd bullhead rail had broken to detach a piece of the head and a section of the web and foot. Both fishing surfaces were highly polished, indicating that the four-hole fishplate had been working for some considerable time. The small flaw at the upper fillet radius of the rail end would be impossible to detect with the Audigage instrument because of its small area. Similarly a crack less than 1/4-in. in extent is unlikely to be found at the bolt hole.
