Updated 3/11/2018:
The refinement of the Steubenville side of the layout continues. Here is the view of the northern part of the layout.
Since the last look, I've added the correct location of the PRR station on N. 6th Street, the Federal Paperboard factory, a re-sized version of The Hub department store, and 5th Street. Both 6th and 5th Streets will be populated with a prototypical sampling of the correct businesses (can't fit them all).
Here's a look at the southern half of Steubenville.
This part of Steubenville will feature the intersection of 4th Street and Market Street, the prominent businesses on lower Market Street, N. 4th Street, and S. 4th Street, and the red light district at Water Street.
The terrain will rise from a low point at the south side of the layout to the northern points near the PRR station. Beyond that track, the terrain will rise sharply over then next 2 feet to meet the backdrop.
