All manner of models pass through my studio – the latest pair are the most unlikely to come together, even as models, never mind the full-size locos. I guess anyone enjoying more than one area of railway modelling can boast a few unlikely pairings in their layout room.
DJ Models lovely Class 71 (foreground) is a BR Southern Region electric locomotive intended to take its power from a conductor rail. They were famous for operating named trains to the Channel ports and turned in many a good performance elsewhere too. As a third rail loco with no auxiliary engine such as that fitted to the Class 73, they relied on current collection using a simple pantograph from overhead tram wires in yards and berthing sidings where there was no conductor rail.
The second model is a TRAXX Class CE 119 ac locomotive – contemporary traction used on heavy freight traffic – very powerful machine indeed. The model is by Brawa which offers it in several electrical configurations. Not cheap!
