Nice looking tunnel portal. How about this for a town idea. Arrange the building around a town square, with the station on one end and commercial buildings on the other three sides. Have the roads that lead out of the square angle towards the hills in the background and put your residential neighborhood there. Along the tracks, have some typical small industries, like machine shops and scrap yards. The area right along the tracks is usually industrial in nature. Looks like the right end of the spur in front of the station would be a good place to add another spur servicing a grain elevator, if you're modeling a midwestern type town. A freight house and a few other rail served industries would be logical in the area by the yard.
