The turn back curve will be 30 inch radius. I made a mock up of the curve with cardboard and decided that punching through the wall into the HVAC closet will create the best scene.
I also updated this drawing with the as-built configuration of track and bridges. The big bridge at Potomac Creek is about 50 percent complete.
I like the fact that I can model a town in this design. In this case, the town will be Brooke. In actuality there was just a church and perhaps a store there. But I plan to add a mill, tavern and a couple houses.
I will depict the town as largely abandoned and now occupied by the Union Army. The blacksmith will be a Union operation for repair of wagon, horse shoes, etc.
The first photo illustrates the mill scene. Since it will be toward the rear of the scene, I may try some selective compression on the structure.

I can't remember where this mill was actually located, but I believe it was someplace in eastern Virginia.

The foreground items shown in the plan at Aquia Landing are piles of supplies such as lumber, barrels, artillery pieces and military stuff. I also read that Haupt had prepared several prefabricated truss bridges for use in the planned drive on Richmond. So I will need to have several of those laying about ready for action.
The Aquia Landing area will be considerably reduced. Fortunately, there should be room for a nice harbor scene. Most of the structures on land will end up being flats. The second photo is about what I hope the building flats at Aquia Landing will look like. Note the track buried in the dirt. A high resolution copy of this photo is available from the Library of Congress. I love to study the details in all the various uniforms and dress of the men depicted in the photo.
The current church at Brooke looks like this, but I am not sure it was there during the 1860s.




Each span gets four. With 3 spans I need twelve arches.
