The British Rail Class 122 is a type of diesel multiple unit which operated primarily on the London Midland, Scottish and the South Western Regions of British Rail between 1958 and 1995. Twenty single car driving units or bubble cars and ten trailer vehicles were built by Gloucester RC&W in 1958 and six survive into preservation. In 1980 the Scottish Region Class 122 were converted to carry parcels and reclassified as Class 131, although the cars themselves were not renumbered.
