BR Class 155

The British Rail Class 155 is a diesel multiple unit. These DMUs were built by Leyland Bus at Workington (incorporating some Leyland National bus components) between 1987 and 1988 as part of British Rail's replacement of its ageing first-generation diesel fleet. 42 units were originally built, however only 7 remain; the other 35 units were converted to Class 153 railcars.
