against outside wall. Then build the inner wall from the 12” x
24” scale lumber using the 16” board as a spacer. Glue the inner
wall into place and remove the spacer board. Using Hydrocal,
I poured all of the castings and let them dry. For the small col-
umns, I removed them from the mold and used a very fine-
tooth saw to cut them to length. I painted all the columns and
walls weathered concrete.
Diorama base
I began construction of the diorama base with ¾” foam board
cut to 24½” x 16”. This can be expanded later, as needed. I cut
and temporarily attached two lengths of Code 55 flex track to
the foam board to get the proper spacing.
I glued the walls and columns in place with white scenery glue,
according to the footprint plan. Finally, I adjusted and marked
the track spacing.

Styrofoam sheets. Track is laid temporarily to check
clearances.
