Steven Lorraine HO Railroad Construction

Here are 2 drawings of the layout.  I first built the workbench for the 1st level which includes a large and small island. Next, I placed 1/2" plywood down for the staging and auxiliary tracks.  I am using sheet cork in the large flat areas like staging, auxiliary and yards.  I am in the process of placing the 1 to 1 track plan down on the roadbed. Hoping to set the proper level for staging, auxiliary areas at 32”.
