The Class 117 DMUs were produced by Pressed Steel in the late 1950s/ early 60s and were based on the similar Class 121 "Bubble Car". They were originally intended for use on suburban services out of London Paddington where they spent several decades. During the 1980s, some moved to Birmingham and Scotland prior to the introduction of newer rolling stock. Like other first generation multiple units, the Class 117s had a long lifespan, with the final units bowing out in 2000. Due to their longevity, many can still be seen at heritage lines across the UK.
