Walthers Cornerstone HO Scale 109' Single-Track Pratt Deck Truss Railroad Bridge Kit - 933-4520

Walthers Cornerstone HO Scale 109' Single-Track Pratt Deck Truss Railroad Bridge Kit - 933-4520 creates a substantial steel bridge for HO scale main lines and railroad right-of-way scenes. Based on standard-design long steel bridges used by railroads across North America since the early 1900s, this Cornerstone model uses a Pratt deck truss configuration with the trusses below the track, making it especially appropriate where overhead and side clearance are important. Part of the Walthers Cornerstone Engineered Bridge System, the finished bridge measures 15 x 2-5/8 x 3-1/8" (38.1 x 6.6 x 7.9cm).

Pratt truss bridges have a long history in North American railroad engineering. With a deck truss design, the main structural framework is positioned below the track rather than alongside or above it, leaving the railroad right-of-way open for tall equipment. Steel Pratt deck truss bridges became a practical choice for longer railroad spans during the 20th century, and examples remain in railroad service today.

Build an HO Scale 109' Pratt Deck Truss Railroad Bridge

The Walthers Cornerstone 109' Single-Track Pratt Deck Truss Railroad Bridge combines a classic prototype with flexible construction options and detailed simulated steel components:

• HO scale 109' single-track Pratt deck truss railroad bridge kit
• Based on standard-design long steel railroad bridges used across North America
• Prototype design in use since the early 1900s
• Deck truss design ideal where overhead and side clearance are important
• Part of the Walthers Cornerstone Engineered Bridge System
• Suitable for steam-, diesel-, and modern-era layouts
• Matches NMRA overhead clearance requirements
• Provides clearance for double-stack cars and other tall modern rolling stock
• Simulated steel construction with detailed girders, latticework, and rivets
• Parts included to build an open-deck or ballasted-deck bridge
• Compatible with Walthers Cornerstone bridge abutments, piers, and bridge accessories
• Designed for use with WalthersTrack Code 83 Bridge Track or other suitable HO track, sold separately
• Easy-to-build styrene plastic kit
• Parts molded in dark gray plastic
• Finished dimensions: 15 x 2-5/8 x 3-1/8" (38.1 x 6.6 x 7.9cm)

The deck truss arrangement makes 933-4520 especially useful for bridge scenes where a tall through-truss structure would be inappropriate or where unobstructed clearance around the track is desired. Use the bridge to carry a single-track main line across a river, stream, roadway, another railroad line, or changing terrain. The open structural framework beneath the track also creates an impressive visual element when the bridge is installed across a deep scenic area.

Expand Your Walthers Cornerstone HO Scale Bridge System

The 109' Single-Track Pratt Deck Truss Railroad Bridge is a natural centerpiece for Walthers Cornerstone bridges and infrastructure. Walthers specifically recommends Single-Track Railroad Bridge Concrete Abutments 933-4551 for completing the ends of the bridge, while Single-Track Railroad Bridge Concrete Piers 933-4550 and Bridge Shoes & Adapters 933-4559 can be used when developing longer structures with additional approach spans.

Combine the finished bridge with Walthers Cornerstone railroad structures and Walthers Cornerstone trackside structures to develop the surrounding right-of-way. Additional bridge components and scene-building details can be found in Walthers Cornerstone accessories and details.
