It's part of the Cornerstone Engineered Bridge System and is designed to be compatible with system abutments and bridge piers. Plate-girder bridges are typically used to cross short distances between 30 and 90'  9.1 to 30.4m. Used for many decades, this design is constructed of several steel sections riveted together to form girders. They're known as through types as the track passes between, rather than on top of the spans. It's ideal for use with WalthersTrack Code 83 Bridge Track 948-83004 or other trackage of your choice. The kit can be built either as a single- or a double-track bridge. Each includes parts for two complete spans, but the design makes it easy to combine additional kits (sold separately) to build a longer or wider bridge if needed. The plastic parts are molded in color and feature authentic rivets and other fine details. As shown the 30' Single-Track Railroad Through Girder Bridge is 4-7\/32 x 2-3\/8 x 1\"  10.7 x 6 x 2.5cm long. \u003cbr\u003e \u003cbr\u003e  \u003cul\u003e \u003cli\u003ePart of the Cornerstone Engineered Bridge System\u003c\/li\u003e \u003cli\u003e For more information about the Cornerstone Engineered Bridge System \u003ca href=\"\/page\/EngineeredBridgeSystem.pdf\"\u003eclick here\u003c\/a\u003e\n\u003c\/li\u003e \u003cli\u003eOne of the most common American railroad bridge designs\u003c\/li\u003e \u003cli\u003eUsed for extra clearance above highways, waterways and other railroads\u003c\/li\u003e \u003cli\u003eFits steam, diesel and modern eras\u003c\/li\u003e \u003cli\u003eGirder heights vary with bridge length\u003c\/li\u003e \u003cli\u003eBuild with open or ballasted deck\u003c\/li\u003e \u003cli\u003eIncludes optional center girder for easy conversion to double track or wider right-of-way\u003c\/li\u003e \u003cli\u003ePerfect as approach spans for bigger Cornerstone and other bridge kits\u003c\/li\u003e \u003cli\u003eEasily added to new or existing scenery\u003c\/li\u003e \u003cli\u003eAuthentic rivets and other details\u003c\/li\u003e \u003cli\u003eMolded in dark gray plastic\u003c\/li\u003e \u003c\/ul\u003e \u003cbr\u003e \u003cbr\u003e","brand":"Walthers Cornerstone","offers":[{"title":"Default Title","offer_id":53179731411309,"sku":"933-4500","price":20.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/7228\/6317\/files\/933-4500_01_4d5e02b0-be28-4a15-932d-cc30b3b0feda.jpg?v=1774983996","url":"https:\/\/walthers.com\/products\/30-single-track-railroad-through-girder-bridge-kit-4-7-32-x-2-3-8-x-1-10-7-x-6-x-2-5cm","provider":"Walthers","version":"1.0","type":"link"}
