Very nice but one route building tip:
Steer clear of spline buildings (or really spline anything besides roads, fences and powerlines). It doesn't look very attractive or as realisitc as a static (higher quality) object. Spline buildings are better for backdrops farther away from the tracks and can be good space filler to keep things realisitc that are farther away from trackside view.
Great route, just my 2 cents,
Davis
