Good point. Seems to be some room to move the track back a bit.I spy with my little eye a couple places where there could be trouble. The Conveyer Log ramp and Sawmill may be too close to curved track. When a locomotive, particularly a diesel rounds those curves, it may hit the log ramp or sawmill.
Others mentioned grades should be contained along the straight sections leaving the curves level. That seems like prudent advice for the curves cresting behind the log loader.
