Motive power relates to all the powered vehicles on the railway.
The original locomotives
Three identical 0-4-2 side tank locomotives were ordered from Kerr-Stuart in 1914 but not delivered until 1916. Unusually these were not of Kerr Stuart design but came from the drawing board of the MWB engineer.
They were named Hampton, Kempton and Sunbury and were always kept in immaculate condition, the paintwork being lined green with a brass dome.
For the technically minded the locomotives had a tractive effort of 4,480lb, the boiler pressure was 150 lb/sq inch, the driving wheels were 24″ diameter, the fixed wheelbase was 36″ and the overall wheelbase was 84″. The cylinders were 8½” diameter with a stroke of 12″. The three locomotives cost a total of £2,187.
It has been suggested that there was a fourth locomotive named Hurst but absolutely no evidence can be found to support this. Unfortunately, they were all scrapped when the line closed but given the necessary finance a replica could be built as we believe that Hunslet still have copies of many, if not all, of the drawings.
