The British Rail Class 142 Pacer are diesel multiple unit passenger trains built for British Rail (BR) from 1985 to 1987. They were built with a high level of commonality with the widely used Leyland National bus. They are part of the Pacer family of railbuses. The last set was withdrawn from service in 2020.
