Description
Build an impressive 109' steel deck-truss bridge on your HO layout with the Walthers Cornerstone 933-4520 109' Single-Track Pratt Deck Truss Railroad Bridge. Based on standard-design long steel bridges used coast-to-coast since the early 1900s, this Pratt truss design offers maximum overhead and side clearance — perfect where double-stacks and other tall cars need to pass through. At 15" assembled, this is the centerpiece span for serious viaducts and crossings.

What's the difference between a Pratt deck truss and a girder bridge?
A Pratt deck truss uses a triangular truss design for greater strength and span length. The "deck" version places the track on top of the truss, providing unlimited overhead clearance — ideal for tall cars and double-stacks.
Does it include the track or piers?
No — bridge structure only. Code 83 Bridge Track (948-83004) and Cornerstone System abutments/piers are sold separately.
What scale is this?
HO Scale (1:87). Assembled bridge measures 15" long — a substantial centerpiece for any layout.
Does it require painting?
Parts are molded in dark gray plastic and can be used as-is, but painting (rust, weathering, prototype steel colors) and weathering will significantly enhance realism.
