A brand new 00 gauge example especially developed by “Dapol Model Railways” as part of their DCC Series. This locomotive is the BR Green with Whiskers Class 121 Diesel Railcar running number W55020. This locomotive comes complete with original box, unopened accessory pack where appropriate, picture card and paperwork.
Sixteen Class 121 single-car, double-ended driving motor vehicles were built from 1960, numbered 55020–55035. These were supplemented by ten single-ended trailer vehicles, numbered 56280–56289 (later renumbered 54280–54289). They have a top speed of 70 mph, with slam-doors, and vacuum brakes. The driving motor vehicles were nicknamed “Bubble cars” by some enthusiasts (a nickname endorsed by final passenger service operator Chiltern Railways).
Upon privatisation of Britain’s railways, the Class 121 fleet was only operated by one passenger company, namely Silverlink, with several more units in departmental duties with Railtrack. Since Chiltern Railways retired its final two units in May 2017, there have been no examples left in revenue-making service. The Class 121 is Britain’s longest serving DMU, operating in passenger service for 57 years until 2017.
