Walthers Cornerstone 933-4502 | 70' Single-Track Through Girder Bridge Kit | HO Scale

Cross any waterway, road, or rail line on your HO layout with the Walthers Cornerstone 70' Single-Track Through Girder Bridge. Based on one of the most common North American railroad bridge designs, this kit is part of the Cornerstone Engineered Bridge System and pairs cleanly with system abutments and bridge piers. The girder is a riveted steel through-type — the track passes between the spans rather than on top — with authentic rivets and detail molded in dark gray plastic. Build it as a single-track bridge, or combine kits and the included optional center girder to expand to double-track or wider right-of-way.
