DB999507 1962-10-07 Derby
Derby attracted all kinds of test vehicles such as No.DB999507, a DMU-like track test vehicle photographed on 7th October 1962. Built in 1958 by D. Wickham the 'Elliott Track Recording Coach' was commonly referred to as the 'Wickham Railbus'. It was a self-propelled four-wheel railbus with one driven axle and a Meadows 97HP horizontal underfloor engine; a lattice girder frame was mounted between the axleboxes to carry the recording equipment. Measurements were possible at up to 30mph and the railbus had a top speed of 55mph when not recording. It was used as a track recording car by the Chief Civil Engineer's Department from around 1958 and was finished in a striking livery of canary yellow with chocolate brown above the waist line. It had a silver roof with red buffer beams and a black underframe. It continued in use in various guises ,even in connection with the Advanced Passenger Train, until around 1991 and was bought for preservation in 1997 and converted to a passenger carrying railbus and is now at the Lavender Line in East Sussex.
