Wired up and working

 

Since I can't hide the Loco Remote and battery in the water tanks, they have to fit under the footplate. Fortunatly, there's plenty of space under there. 

The Loco Remote is fixed to one end with some Velcro. The tiny battery tucks onto a ledge I made with plastic, held to the chassis with the original fixing screws. It seems pretty secure there. 

Best of all, Loco Remote include all the cables, with plugs fitted, required to entend the leads the length of the chassis. It's a very neat install really, and works perfectly.
