Wickham car
The “Elliott Track Recording Coach” was commonly referred
to as the 'Wickham Railbus' and was built in 1958 by D. Wickham of Ware,
Hertfordshire. It was a self-propelled four-wheel railbus No: DB999507 with one driven axle and had a Meadows 97HP horizontal underfloor engine. It was used as a track recording car by the Chief Civil Engineer's Department from around 1958, before the BR Research Division was formed and was fitted with an early computer system supplied by Elliott Brothers (London) Ltd (Elliott Automation). My thanks to Martin Collins for the following information: It was used in the early days of the computer
development of suspension design to measure track parameters. It towed a
sled 50m behind it and through various electrical and optical means measured
such things as cant, gauge, curvature all to be fed into a computer program
to represent typical track - probably by punched cards processed in the
punch room at the RTC. One peculiarity was that it only had brakes on one
wheelset - and certainly would not be allowed out on the main line these
days! Its original livery was canary yellow with chocolate brown above the waist line. It had a silver roof with red buffer beams and a black underframe with a lattice girder frame mounted between the axleboxes, which carried the recording equipment. It was known affectionately to the staff at the R&DD as 'The Yellow Peril'. It was designed to record at 30 mile/h but could transit at up to 55 mile/h. Here are some pictures of the vehicle when built, in R&DD service and on a special working. |
The Wickham was sold to the East Lancashire Railway in 1997 and later moved to the Middleton Railway on 11th June 2003. It is currently based at the Lavender Line in Isfield, East Sussex and is now privately owned. |
