Atlas N Scale Code 55 15" Radius Curved Track – 6-Pack – ATL2018

Atlas N Scale Code 55 15" Radius Curved Track – 6-Pack – ATL2018 includes six full-section curved track pieces for building smooth, consistent curves on N scale model railroads. Part of the Atlas N Scale Code 55 track system, each section features fine nickel silver rail with prototypical brown ties for realistic-looking trackwork.

Atlas specifies that 16 full sections create a complete 360° circle at the 15" radius. This means each ATL2018 curved track section provides 22.5° of curvature, while the six pieces included in this package provide a combined 135° of 15" radius curvature.

15" Radius Full-Section Curved Track

ATL2018 maintains a consistent 15" radius throughout each curved section. Its fixed sectional geometry makes it easy to create predictable curves for mainlines, branch lines, passing sidings and other portions of an N scale railroad.

Each package includes:

• 6 curved track sections
• 15" radius
• 22.5° of curvature per section
• 135° of total curvature per 6-pack
• 16 sections required for a complete 360° circle

Understanding 15" Radius Track Geometry

The 15" measurement describes the radius of the curve, while each individual full section covers 22.5° of a complete circle. Connecting additional sections increases the total angular coverage while maintaining the same 15" radius.

With 16 sections forming a complete circle, 4 sections create a 90° quarter-circle, 8 sections create a 180° half-circle and 16 sections create a complete 360° circle.

Broader Curves for N Scale Layouts

The 15" radius provides a broader curve than the 10", 11.25", 12.5" and 13.75" radius sectional curves in the Atlas Code 55 system. This makes ATL2018 an excellent option when layout space permits more gradual curvature and a broader overall track arrangement.

These 15" radius sections can be useful for:

• Mainline curves
• Branch lines
• Passing sidings
• Station approaches
• Yard approaches
• Staging areas
• Sectional track plans requiring predictable curve geometry

Check Your Equipment's Minimum Radius

Minimum-radius requirements vary between N scale locomotives and rolling stock. Always check the recommended minimum radius for your equipment when planning a layout, particularly when operating longer locomotives, passenger cars or freight equipment.

Atlas N Scale Code 55 Track

Atlas N Scale Code 55 track features fine nickel silver rail and simulated brown wood ties for realistic N scale trackwork. The complete system includes curved track, straight track, flex track, turnouts and crossings, allowing modelers to build detailed layouts with a consistent Code 55 track system.
