Each piece maintains a consistent \u003cstrong\u003e18-inch radius\u003c\/strong\u003e while providing a \u003cstrong\u003eone-third-length curved section\u003c\/strong\u003e for greater control over fixed sectional track geometry.\u003c\/p\u003e\n\n\u003cp\u003eThese compact curved sections are especially useful when a standard or half-length 18\" radius curve would turn the track farther than needed. The 1\/3 section provides a smaller amount of curvature while maintaining the same 18\" radius, helping model railroaders accurately position curves between straight track, turnouts, crossings and other fixed track components.\u003c\/p\u003e\n\n\u003cp\u003eEach section features \u003cstrong\u003esolid nickel silver Code 100 rail and black injection-molded plastic ties\u003c\/strong\u003e, matching Atlas' traditional HO Code 100 track system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Does \"1\/3 18\" Radius\" Mean?\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e18\" radius\u003c\/strong\u003e describes the actual radius followed by the curved track. The \u003cstrong\u003e1\/3 designation\u003c\/strong\u003e refers to the shorter amount of arc provided by the individual track section compared with a standard Atlas 18\" radius curved track piece.\u003c\/p\u003e\n\n\u003cp\u003eThis is \u003cstrong\u003enot a 6\" radius curve\u003c\/strong\u003e. The track maintains the same 18\" radius while turning through a smaller angle. Think of it as a shorter piece of an 18\" radius curve rather than a tighter curve.\u003c\/p\u003e\n\n\u003cp\u003eThis smaller amount of curvature makes ATL835 particularly useful as a \u003cstrong\u003ecurve adjustment or geometry-filler piece\u003c\/strong\u003e when working with fixed Atlas sectional track.\u003c\/p\u003e\n\n\u003ch3\u003eFine-Tune 18\" Radius Track Geometry\u003c\/h3\u003e\n\n\u003cp\u003eAtlas sectional track uses predetermined lengths, radii and angles. Standard 18\" radius curved sections are useful for building the majority of a curve, but more complicated track arrangements can require smaller adjustments to make everything align properly.\u003c\/p\u003e\n\n\u003cp\u003eThe 1\/3 18\" radius section gives you another geometry option. It can be combined with standard and half-length 18\" radius track to control exactly how much total curvature is incorporated into a particular section of your layout.\u003c\/p\u003e\n\n\u003cp\u003eThis can be especially useful around turnouts, crossings, sidings, yards and junctions where the location and angle of the connecting track need to be adjusted without changing to a different curve radius.\u003c\/p\u003e\n\n\u003ch3\u003eAtlas HO Code 100 1\/3 18\" Radius Track Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e4 curved track sections per package\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eHO Scale model railroad track\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e18\" fixed curve radius\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eOne-third-length 18\" radius curved sections\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eMaintains the same 18\" radius as standard Atlas 18\" radius track\u003c\/li\u003e\n\u003cli\u003eProvides a smaller amount of curvature than standard or half-length sections\u003c\/li\u003e\n\u003cli\u003eUseful for precise sectional track geometry adjustments\u003c\/li\u003e\n\u003cli\u003eHelps align curves with straights, turnouts, crossings and other components\u003c\/li\u003e\n\u003cli\u003eCode 100 rail profile\u003c\/li\u003e\n\u003cli\u003eSolid nickel silver rail\u003c\/li\u003e\n\u003cli\u003eBlack injection-molded plastic ties\u003c\/li\u003e\n\u003cli\u003eDesigned for Atlas HO Code 100 sectional track systems\u003c\/li\u003e\n\u003cli\u003eCan be combined with other Atlas 18\" radius curved track sections\u003c\/li\u003e\n\u003cli\u003eAtlas manufacturer item number 0835\u003c\/li\u003e\n\u003cli\u003eFusion Scale Hobbies SKU ATL835\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCombine Standard, 1\/2 \u0026amp; 1\/3 18\" Radius Curves\u003c\/h3\u003e\n\n\u003cp\u003eThe different Atlas 18\" radius sectional track pieces allow model railroaders to maintain the same curve radius while changing the total amount of turn.
