Pacer Railbuses (Class 140 and 141)
There are at least a minimum of 5 Pacer Units Preserved, but many more are still in operation, as can be seen in the other part of this section.
Class 140
Keith and Dufftown Railway
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, in 1980.
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.
The sole surviving member of the class, No. 140001, formed of Nos 55500+55501 has been preserved and is currently at the Keith and Dufftown Railway.
Class 141
Colne Valley Railway
Iranian Railways
Midland Railway Centre, Ripley
Weardale Railway
