Design
Based on the single car railbus prototypes, the class 140 was built to BR's then stringent regulations regarding crashworthiness and resistance to end loading in 1980. This meant that it lost its lightweight 'bus on a wagon' look and was much more substantial.
The original traction power train consisted of a Leyland TL11 200 HP engine, a Self-Changing Gears mechanical automatic gearbox and a Gmeinder final drive unit on each car driving only one axle.
History
The unit was built between 1979 and 1981, had a press launch in June 1981, and then toured the UK for trials and as a demonstration unit. During 1985, the unit was in use as a driver training vehicle. From September 1986, the set was allocated to Neville Hill. By 1994, prior to sale, the unit was kept at Neville Hill depot as a parts donor.
Legacy
The Class 140 formed the basis of the design of the production Pacer sets of Class 141 introduced in 1984 and Class 142 introduced in 1985.
