If you've ever cut a piece of Snap Track because the math didn't land on a 9-inch boundary, this is the piece you should have reached for instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy a 3-inch filler matters.\u003c\/strong\u003e HO Code 83 Snap Track is built around the 9-inch base straight (Atlas 520) and its 6-inch counterpart (Atlas 521). When you lay out a yard ladder, fit a passing siding inside a 4×8 sheet, or chase a turnout's offset through a curve, the geometry rarely lands exactly on a 9-inch boundary. The 3-inch filler bridges the final gap so your turnouts and curves snap into place at the correct centerline — no cutting, no shimming, no rail joiner misalignment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCode 83 vs. Code 100.\u003c\/strong\u003e Code 83 nickel-silver rail puts the railhead within roughly 4% of the prototype's modern 132 lb\/yard mainline rail, visibly finer than oversized Code 100 — but at nearly the same price. Brown molded ties carry centerline nail holes for Atlas #2540 track nails, so you can pin the geometry exactly where you want it before ballasting, then leave the nails in place or pull them once the ballast cures.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale:\u003c\/strong\u003e HO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Code:\u003c\/strong\u003e Code 83 nickel-silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSection Length:\u003c\/strong\u003e 3\" (76.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces per Pack:\u003c\/strong\u003e 4 (12\" \/ 305 mm total)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTie Color:\u003c\/strong\u003e Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e All Code 83 Snap Track + Custom Line systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Atlas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU \/ Item Number:\u003c\/strong\u003e 522\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 520\u003c\/strong\u003e — Code 83 9\" Straight (6pc), the base mainline length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 521\u003c\/strong\u003e — Code 83 6\" Straight (4pc), the half-length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 523\u003c\/strong\u003e — Code 83 1.5\" Straight (4pc), the finest single adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 525\u003c\/strong\u003e — Code 83 2\" Straight (4pc), fits between #523 and #522\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAtlas 524\u003c\/strong\u003e — Short Straight Assortment (10pc), a sampler when you don't know which length you need\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Atlas","offers":[{"title":"Default Title","offer_id":45097017508022,"sku":"150-522","price":7.96,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/5131\/1286\/files\/57_26397997-14c2-44b4-89dd-435c00120c77.jpg?v=1779570546","url":"https:\/\/oakvillemodeltrains.com\/products\/atlas-522-ho-scale-code-83-3-straight-track-4pcs","provider":"Oakville Model Trains Depot","version":"1.0","type":"link"}
