John,
Have you seen my track plan? It just about fits into an 8 x 4 rectangle And I will probably have one controller, which will be a powercab as Anto advised me The minimum curve is 2nd radius, which are OK with the 201s, but I'll mainly be using the 141s and (when they come out!) 121s in the freight yard, where space is tight, as you're right, they would look better. The 201s and 071s will be used for the long platform and the liner trains' main siding. Thanks for the advice!
