Thanks for all your help. Yes, I know, it is short. This is really as much about seeing if I enjoy model trains, creating scenery and buildings etc, seeing if i'm any good at it. Ideally it'd be 30ft long and 10 ft wide! If I enjoy this, I'll look at doing another layout. The loft is empty!!! I'm not past the point of no return
I'm doing it in the early 60's era, just before it was closed. By that time, the multi carriage steam trains had gone, and a single car DMU was serving the station. Goods wise, I reckon i might have 5 or 6 wagons each side, and just move them about a bit, with a GWR Pannier Tank. So all my trains are nice and short.
So here it is, roughly laid out [upside down to my original sketch]- the curves look ok, but i'll test run them before pinning them down. You can see the original track plan on which I'm basing it [loosely].
Thanks for the advice on the power supply for accessories - will scout around for something with a lower amp output.
