Atlas HO Code 100 15" Radius Curved Track – 6-Pack – ATL831

Atlas HO Code 100 15" Radius Curved Track – 6-Pack – ATL831 includes six fixed-radius curved sectional track pieces for building compact curves, loops and HO scale model railroad track plans. Each section follows a 15-inch radius, providing consistent geometry when constructing curves with Atlas Code 100 sectional track.

Each package contains six curved track sections. Atlas specifies that 12 sections form a complete 15" radius circle, meaning one ATL831 6-pack provides exactly half of a complete circle, or 180° of curvature.

Part of the traditional Atlas HO Code 100 track system, these sections feature solid nickel silver Code 100 rail and black injection-molded plastic ties for durable, dependable HO scale track construction.

15" Radius for Compact HO Scale Curves

The 15" radius allows model railroaders to construct relatively tight curves where layout space is limited. This can make the track useful for compact HO layouts, small loops, industrial areas and other track plans where a broader-radius curve cannot be accommodated.

Keep in mind that a 15" radius is a relatively sharp curve in HO scale. Locomotive and rolling stock minimum-radius requirements should always be checked before designing a layout around 15" radius track. Longer locomotives and cars may require broader curves for reliable operation.

How Much Track Is in One Package?

• 6 curved track sections per package
• 15" radius
• 12 sections required for a complete circle
• One 6-pack creates 180° of curvature
• Two 6-packs provide enough curved sections for one complete 15" radius circle

This makes planning simple: one package can create a complete semicircle at each end of certain point-to-point or switching-style track arrangements, while two packages provide the 12 curved sections necessary for a full circular loop.
