Pete,
I don't know why but I couldn't open your layout plan directly (got the dreaded red cross
) so ended up downloading it onto my PC and opening it with a bit of jiggery pokery in Photoshop.
There is certainly plenty of operational interest with all those running-lines. I bet you sit for hours watching your favourite trains go round.
I agree with your comments about H & M controllers. They are great and far better than a lot of the modern junk you get nowadays. I'm using Gaugemaster controllers on my N-scale layout......they're not bad but nowhere near as robust as the H & M's.
Keep up the good work.
