I have many irons in the fire this Ides of March. I am exploring some ways to super detail the bridge. Also underway is the WV scenery. That is taking much longer than I anticipated or wish. Visualizing a 3-D topography in a tight space is a challenge. Carrying it off will be even more challenging as it includes accurate placement of abutments, piers, and plaster castings.
The drainage ditch (about 5' long) between the eastern bridge approach tracks and the backdrop is nearly complete. It has received scenery and will soon get water.
More when I know it.
