Close-up showing how I made the stringers that run under the trestle trackage. I used 3 strips of scale 2x12 lumber, with tiny 2x12 spacer blocks placed at 1.5 inch intervals. These are all glued together and held with miniature clothespins to dry. These two 3-strip beams are then epoxied under the track, one under each rail. Finally, I insert the bents in place, clipping the legs to suit the terrain, and checking the track for level in all directions.
