Mark, i would like to see a dwg of the suggestion. I do not see enough room to do what I imagine is suggested based on the last scarm dwg. I suppose 2 curved switches would work, but not sure that gains you much. Ross' are what 072/054? I agree the blue boxes are too high - I am thinking 2/3 lower 1/3 upper. Remember the golden ratio where there are eye pleasing proportions?
This is what I am thinking as an example, although in my case it is 1/3 lower and 2/3 higher although I may raise this more or stagger the heights. You can see the trolley poles in the upper section. Coming into the photo I will have the elevated trestles to provide service to the engine house further right. To the eye, the elevated trolley will run past the upper windows of the background buildings. If they will fit, I have several unbuilt Downtown Deco buildings which would go well at street level under the elevated track. A Korber apartment building will go on the upper level. These two structures are the Korber General Light & Power Office Building cut in half. I always thought it was too thin to be an office building, but as a background building great. Funny the apartment building is the same casting with the corbel section cut off, but with some adds. Rustoleum primer does not like to stick to this resin. Krylon seems OK.
