Atlas N Scale Code 55 21.25" Radius Curved Track – 6-Pack – ATL2028

Atlas N Scale Code 55 21.25" Radius Curved Track – 6-Pack – ATL2028 includes six full-section curved track pieces for building broad, sweeping curves on N scale model railroads. Part of the Atlas N Scale Code 55 track system, each section features fine nickel silver rail with simulated brown wood ties for realistic appearance and dependable operation.

Atlas specifies that 16 full sections create a complete 360° circle at the 21.25" radius. This means each ATL2028 curved track section provides 22.5° of curvature, while the six pieces included in this package provide a combined 135° of 21.25" radius curvature.

21.25" Radius Full-Section Curved Track

ATL2028 maintains a consistent 21.25" radius throughout each curved section. Its fixed sectional geometry makes it easy to create predictable curves while providing broad, gradual track geometry for N scale layouts with sufficient space.

Each package includes:

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

Understanding 21.25" Radius Track Geometry

The 21.25" 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 21.25" 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.

Broad 21.25" Radius Curves for N Scale Layouts

A 21.25" radius provides broad sectional curve geometry for an N scale railroad. For layouts with sufficient space, broader curves create a more gradual change in direction and can provide a more realistic appearance for mainline trains, passenger equipment and longer locomotives and rolling stock.

These 21.25" radius sections are especially useful for:

• Mainline curves
• Passenger routes
• Passing sidings
• Station approaches
• Yard approaches
• Staging areas
• Broad sectional track arrangements
• Layouts designed around sweeping, gradual curves

Full and Half-Section 21.25" Radius Track

ATL2028 provides the full-section 21.25" radius curve. Modelers who need smaller adjustments within the same radius can combine these pieces with Atlas 21.25" radius half-section curved track. Both maintain the same radius while providing different sectional lengths for greater flexibility when planning a layout.

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.
