Dapol Class 121 (121020) Railtrack Chiltern Railways Blue Exclusive Edition is an OO‑gauge (1:76) model of a single‑car diesel multiple unit in Chiltern Railways blue livery. It is supplied as an exclusive edition and is not fitted for DCC operation.
The model features a die‑cast chassis, NEM pocket coupling mounts with a tension‑lock coupling, and is capable of navigating a minimum radius of 2. It represents a Class 121 unit built by Pressed Steel Company between 1960 and 1961, with a passenger capacity of 65.
In the prototype era the units were operated by Arriva Trains Wales, British Rail, Chiltern Railways, Silverlink, Network Rail and Railtrack, mainly on local passenger services. The class remained in service until 2017, with 15 examples surviving. The Dapol part number is 4D‑009‑HAT04 and the model depicts the initial privatisation period.
