Well I believe I have changed my layout about 10 times trying to move the trains in both directions. I probably have 10 locomotives so sidings are an issue if you want all locomotives on the layout at the same time. Roads are next and the color or decision to simulate Asphalt, concrete or dirt is the next decision. Going for 1930's to early 1950's era with a Xmas theme, train station, passenger, small town set up. what colors are you guys using to simulate roads ? I am going to paint for now.
