Atlas N Scale Code 55 20" Radius Half-Section Curved Track – 6-Pack – ATL2027

Atlas N Scale Code 55 20" Radius Half-Section Curved Track – 6-Pack – ATL2027 includes six half-section curved track pieces designed for making precise adjustments to broad 20" radius 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, prototypical-looking trackwork.

Each half section maintains the full 20" radius while providing a shorter curved section than the corresponding full-section track. This gives modelers additional flexibility when building sectional track plans where a full curved section would provide more curvature than needed.

20" Radius Half-Section Curved Track

The term half section refers to the shorter curved track section—not half of the radius. ATL2027 remains a true 20" radius curve, allowing it to be combined with corresponding full-section 20" radius track while maintaining consistent curve geometry.

Each package includes:

• 6 curved track sections
• 20" radius
• Half-section curved track geometry
• Fine nickel silver rail
• Simulated brown wood ties

Fine-Tune 20" Radius Curves

Half-section curves provide greater control when building with fixed sectional track. When a full curved section creates too much change in direction, ATL2027 provides a shorter section while maintaining the same 20" radius throughout the curve.

These half-section curves are especially useful for:

• Fine-tuning sectional track geometry
• Completing curves with specific alignment requirements
• Adjusting approaches to turnouts and crossings
• Connecting curved and straight track arrangements
• Mainline curves
• Passing sidings
• Passenger routes
• Station approaches
• Staging areas

Same 20" Radius – Shorter Curved Section

ATL2027 should not be confused with a smaller-radius curve. A half section does not reduce the 20" radius to 10". Instead, the track follows the same 20" radius geometry while providing a shorter curved section for more precise sectional track planning.

This makes half sections particularly useful when combining multiple pieces of sectional track to achieve a specific alignment without changing to a different curve radius.

Broad 20" Radius N Scale Curves

A 20" radius provides broad curve geometry for an N scale railroad. For layouts with sufficient space, broad curves can create a more gradual-looking route and are particularly useful when designing mainlines, passenger routes, passing sidings and other areas where more sweeping trackwork is desired.

ATL2027 adds additional flexibility to that broad-radius geometry by allowing smaller sectional adjustments while maintaining the same consistent 20" radius.

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.
