The British Rail Class 122 diesel multiple units were built by Gloucester RC&W in 1958. Twenty single-car driving motor vehicles, called "Bubble Cars", were built, numbered 55000-55019. These were supplemented by ten trailer vehicles, numbered 56290-299 (later renumbered 54290-299).

Three Scottish Region cars (55013-55015) were converted to carry parcels traffic and were reclassified Class 131, though the vehicles themselves were not renumbered.
