Thanks Mike. Steve, you're the first person to mention the lack of clearance under the girder bridge. Good catch! I actually did that on purpose. My thinking was this: since the majority of trains would be on the branch line (upper track), I wanted the grade they would have to travel on to be minimal. It is roughly 1.3%. The lower track under the girder bridge hits the wall just a foot after the bridge, so no big deal. It was more important for me to have a smaller grade.
