Atlas HO Code 100 18" Radius Curved Track – 6-Pack – ATL833

Atlas HO Code 100 18" Radius Curved Track – 6-Pack – ATL833 includes six fixed-radius curved sectional track pieces for building HO scale curves, loops and complete model railroad track plans. Each section follows a consistent 18-inch radius and features solid nickel silver Code 100 rail with black injection-molded plastic ties.

Each package contains six 18" radius curved track sections. Atlas specifies that 12 sections form a complete circle, meaning one ATL833 6-pack provides exactly half of a complete circle, or 180° of curvature. Two packages provide the 12 curved sections needed to construct a full 18" radius circle.

18" Radius HO Scale Curved Track

The 18" radius is a common compact curve size for HO scale sectional track layouts. Compared with tighter 15" radius track, the broader 18" radius provides a more gradual curve while still allowing a complete loop to fit into a relatively compact layout area.

These fixed-radius sections are useful for building continuous-running loops, semicircles, return curves and other predictable track arrangements. Because every section follows the same radius and angular geometry, pieces can be connected together without having to shape or measure the curve manually.

As with any HO scale curve, always check the minimum-radius requirements of your locomotives and rolling stock. Longer locomotives and cars may require broader-radius track for reliable operation and a more realistic appearance.

How Much Curved Track Is Included?

• 6 curved track sections per package
• 18" fixed radius
• 12 sections form one complete circle
• One 6-pack provides 180° of curvature
• Two 6-packs provide enough sections for one complete 18" radius circle

This makes planning a sectional track layout straightforward. One package provides enough curved track for a complete semicircle, while two packages provide the curved sections required for a full circular loop.
