Not a brick train but roadbed being weighted till the silicone caulk is cured. Revised construction is the .500-inch plywood (recycled from 2008) on original dominos, with 2-inch Styrofoam topped with .500-inch thick extruded dense foam.
Spacers for the super elevation in place.
Track is pre-painted and weathered as are the #10 Fast Tracks turnouts for the passenger station spur.
