An express passenger train, consisting of two six-coach diesel-electric sets, derailed near Hither Green at about 70 mph, when the leading pair of wheels of the third coach struck a wedge-shaped piece of steel that had broken away from the end of a running rail, and became derailed. The initial derailment was caused by the fracture of a rail as the train was passing over it. The fracture was caused by excessive working of the joint resulting from unsatisfactory support conditions including: inadequate clean ballast under the two original concrete joint sleepers; the absence of a rubber pad under the rail seat; and substitution of a wood sleeper for the running-off concrete sleeper which cracked because the pad was missing. Due to unsatisfactory track maintenance, a speed restriction of 60 mph was placed on the track.
