Covering the helix

We have started covering the helix, and there is obviously a lot of work to do. The helix is located at one end of the railroad, nearest the door into the railroad room. The coal tipple seen in previous photos is on the upper level and just to the left of this image.

The top of the helix can be seen in the background. Track seen here is visible between what will be two tunnel portals, and is headed down to the lower level. Material here is 1 1/2"pink insulation foam board. John Ellenbracht is doing the work.
