Atlas N Scale Code 55 18.75" Radius Half-Section Curved Track – 6-Pack – ATL2025

Atlas N Scale Code 55 18.75" Radius Half-Section Curved Track – 6-Pack – ATL2025 includes six half-section curved track pieces designed for making precise adjustments to broad 18.75" 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 18.75" 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.

18.75" Radius Half-Section Curved Track

The term half section refers to the shorter curved track section—not half of the radius. ATL2025 remains a true 18.75" radius curve, allowing it to be combined with corresponding full-section 18.75" radius track while maintaining consistent curve geometry.

Each package includes:

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

Fine-Tune 18.75" 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, ATL2025 provides a shorter section while maintaining the same 18.75" 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 and yard approaches
• Staging areas

Same 18.75" Radius – Shorter Curved Section

ATL2025 should not be confused with a smaller-radius curve. A half section does not reduce the 18.75" radius. Instead, it follows the same 18.75" radius geometry while providing a shorter curved section for more precise sectional track planning.

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

Broad N Scale Curve Geometry

The 18.75" radius provides a broad curve for N scale layouts and is wider than the 10", 11.25", 12.5", 13.75", 15", 16.25" and 17.5" radius sectional curves in the Atlas Code 55 system. For layouts with sufficient space, broader curves can provide more gradual-looking trackwork while the half-section design gives modelers additional flexibility when fine-tuning the route.

The broad 18.75" radius can be particularly useful when planning mainline routes, passenger operations and other areas where more gradual curvature is desired.

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.
