"HSE found no evidence to suggest that the condition of the track was a contributory factor. Initial findings indicated that the derailment was caused by a traction motor falling onto the track from beneath the 5th carriage of the train. The motors are mounted on the bogies and are secured by four main bolts. There have been three previous incidents of a motor either falling off, or becoming dislodged from, Central Line stock, as a result of which LUL instigated remedial measures including checking all motor securing bolts every five days. The motor bolts of this particular train had been checked 48 hours before the derailment. The Central Line rolling stock is around 10 years old."
