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").
