On Friday, 21 September 1951 the 08:20
Liverpool Lime Street to
London Euston passenger service consisting of 15 coaches hauled by a
Princess class Stanier Pacific began to de-rail south of
Weedon,
Northamptonshire, on the
West Coast Main Line south of Rugby, at a speed of 65 mph and finally crashed, killing 15 people and injuring 35 more. The footplate crew survived and protected their train in spite of being severely shocked. The accident enquiry, conducted by Lt Col G R S Wilson, found the track to be in good condition and the speed of the train not to be excessive. However this was the first trip out for the locomotive, No 46207
Princess Arthur of Connaught after its
bogie wheelsets had been swapped round. The enquiry concluded that the derailment was caused by an excessively tight bogie
axlebox. The approximate location of the collision was , less than a mile south-east of the 1915 derailment and close to the signal-box at
Heyford south of Stowe Hill tunnel where the occupants were able to see the accident. ==References==
