This neat-looking bridge was used on every railroad in North America. It was the strongest and cheapest way to span any little stream or ditch. The kit includes strip basswood, white pine ties (N scale ties are basswood), Nut/Bolt/Washer castings, and actual steel rods. Full-size templates are enclosed for various clearances: 16′ wide for standard NMRA Specs and 14′ for Narrow Gauge layouts. This design can also be modified for roadways. Proper size drill bit included. The ‘S’ scale model’s clearance is excellent for On30.
