Have had a little change of plan, after seeing this youtube vid
http://www.youtube.com/v/-aBM2uPL2fYI'm inspired by the way these baseboards are set up.. So I have purchased a bunch of 1'x4'x3/4" boards that I'm going to use for the layout. If anyone has any experience with this method of building please chime in. I love the way there are some tiny modules but they are part of a much larger whole. I love scenery and small scenes such as these are things I can realistically see myself building and completing.
I'm still sticking to the station plan above but without the depth, so the town scenes will be at the ends of the boards (the station will now basically be on 2 elevated 4' boards with the station centrally. Hope to get some pics of the board assemblies soon (I have to cut some supports, screw them together and paint them).
Next steps after that is laying the track and starting to ballast between the unitrack. (at the same time I'll be building the other 8' viaduct section for the backside of the layout. Ambitious goals but I should get a little time soon
