Pacer (train) - Class 140

Class 140

The Pacer series was the result of an experiment to see whether the possibility of using bus parts to create a diesel multiple unit was viable. The initial prototype, known as LEV-1, was a joint project by the British Rail Research Division and Leyland Motors using a bus body mounted on a modification of an existing freight vehicle underframe (HSFV1). This was followed by the two-car prototype class 140, which was built in 1984 at the British Rail Engineering Derby works.
