A green diecast two-rail BR Type 2 Metropolitan-Vickers prototype Diesel Co-Bo Locomotive D5702 (Hornby-Dublo model number 2233), with grey roof and white floor-stripe and plastic windows, from the early 1960s. The model was announced in Meccano Magazine in December 1961.
The original locomotive
Locomotive D5702 was one of a set of twenty Metropolitan Vickers Class 2 locomotives (BR Class 28) built in 1958-59.
This experimental loco class locomotive had the odd distinction of having different wheel configurations for each of its two bogies – one was six-wheel, and the other four-wheel, giving rise the wheel classification "Co-Bo".
The distinctiveness of the design (for UK railways) meant that the locomotive ended up being modelled by a number of manufacturers, and was even used as a character on Thomas the Tank Engine (as a diesel engine called "Bo-Co").
