Timber trestles on the C&TT Railroad
The underside (left) of the truss bridge at Silver King Jct. shows the heavy supporting timbers and the wooden abutments. Also note the short strips of wood at the vertical truss rod locations. What looks like separate timbers as the main beams (right) are actually cuts
made with a hobby knife. Both beams are single pieces of scale 24″ square stripwood. The diagonal railing braces and the braces be- tween the bents can be seen. A vinegar/steel wool rusting solution was liberally applied where the n.b.w. castings and brads were used.
The Grandt Line n.b.w. castings and the timber planks (above left) serve as a “shoe” to re- inforce the 8″×12″ timber beams where they rest atop the twin bents. The truss rod pairs (above) along with the short timbers are located at the end of the n.b.w. castings. It is easy to see the three sets of trusses used in each side component. The truss rods (left) are made of music wire cut to length and chemically blackened with circuit etching and gun bluing solutions and are inserted into square blocks of wood. The girder bridge (below) has a short flange of styrene attached to each of the side pieces to hold them in place.

epoxy. It took a while to make
up the number that I needed, but I did it whenever I was working on another project at the workbench. I must have done something right
back then because the trestle is still standing. Considering that it has been
