What it does

230mm long bridge fits standard model train layouts so your railroad scene looks complete
54mm internal width matches NEM 102 standard, so trains roll through without binding
Roof section adds strength to the structure so it stays rigid during play and display
Simple print design with 45-degree rotations makes assembly straightforward for you

Build a model railroad that feels real. This HO scale bridge brings your miniature train world to life with proper engineering that actual model railroaders trust.

The bridge spans 230mm long and fits most printer beds. Your trains cross through a 54mm-wide opening that matches official NEM 102 standards, so everything connects properly. A roof section covers the top, giving the structure the strength it needs to hold up through years of play and display. The track bed sits 4mm above the bottom, just like real bridges do.

You get all the parts you need to assemble a bridge that looks and works like the real thing, sized perfectly for HO gauge model trains.
