The British Rail Class 155 is a diesel multiple unit passenger train. These DMUs were built by Leyland Bus at Workington (incorporating some Leyland National bus components) between 1986 and 1987 as part of BR's replacement of its ageing first-generation diesel fleet. 42 units were originally built, of which only 7 remain; the other 35 units were converted to Class 153 railcars.
