I'm at the point of starting to install the supports for the backdrops on the peninsulas of the D&J Railroad. The previous layout was an around the wall layout so I didn't have the opportunity to experiment with the height of the backdrops when there is track on the other side of the benchwork.
Right now I have the 2X4s cut to 20" above the roadbed. I intend to apply 1/4" drywall to them and paint it sky blue.
Any suggestions as to a better height solution?
