The British Rail Class 140 was the prototype of the Pacer diesel multiple unit. Much of the bodywork was constructed using Leyland National bus components, with the exception of the cabs, between 1979 and 1981. The sole member of the class has been preserved and is at the Keith and Dufftown Railway.
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 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.
The unit was purchased for preservation and collected from Leeds in February 1995. The sole member of the class, 140001, formed of cars 55500+55501, has been preserved and is at the Keith and Dufftown Railway This unit is at Dufftown Station. It is being restored to its former state by volunteers at the railway.
