Dapol Class 121 BR Chocolate & Cream W55020 Exclusive Edition is an OO gauge (1:76) model of a single‑car diesel multiple unit. The model is die‑cast, fitted with NEM pockets and a tension‑lock coupling, and can negotiate a minimum radius of 2. It bears the Great Western Railway chocolate and cream livery and carries the manufacturer part number 4D‑009‑HAT01.
The prototype was built by the Pressed Steel Company between 1960 and 1961, had a passenger capacity of 65 and was used for local passenger duties. It operated under several operators including Arriva Trains Wales, British Rail, Chiltern Railways, Silverlink, Network Rail and Railtrack, and remained in service until 31/12/2017. Fifteen units survive today.
The model is listed as an exclusive edition with DCC fitting service not applicable. It represents the British Rail sectorisation period.
