Mainline Railworks HOn3 Sectional Curve Track

Mainline Railworks HOn3 Curved Track

Mainline Railworks HOn3 Curved Track is designed to help modelers create smooth-running narrow gauge railroads with reliable geometry and easy layout planning. Whether you’re building a compact mountain line, a temporary tabletop setup, or expanding a permanent layout, these sectional curves make HOn3 construction simpler and more enjoyable.

All curved track sections are sold individually, allowing you to build exactly the radius, angle, and layout configuration your railroad requires.

🚂 Why This Matters

Consistent curve geometry is critical in narrow gauge modeling. Properly matched sectional curves reduce derailments, improve operation, and make layout construction far less frustrating—especially for new HOn3 modelers.

⚠️ Builder Tip

Using consistent curve geometry throughout your layout improves both appearance and operational reliability.

📐 Curve Geometry Options

Mainline Railworks HOn3 curved sectional track is available in multiple radius and angle configurations, allowing modelers to build everything from compact tabletop loops to broader, more prototypical narrow gauge railroads.

Available Angle Options

A — 22.5° Sections

• 16 sections complete a full circle

• Excellent for balanced tabletop and oval layouts

• Popular for general-purpose HOn3 operations

B — 11.25° Sections

• 32 sections complete a full circle

• Ideal for smoother transitions and precise layout planning

• Great for modular and advanced layouts

C — 45° Sections

• 8 sections complete a full circle

• Perfect for compact layouts and quick assembly

• Ideal for beginner and temporary setups

📏 Radius Options

Multiple radius options are available to support:

• Compact shelf layouts

• Tabletop railroads

• Mining branches

• Modular systems

• Broader scenic mainlines

Smaller radii work well for tight spaces, while larger radii provide smoother operation and a more prototypical appearance.

🔄 Layout Flexibility

Because sections are sold individually, curved track can be mixed and matched with straight sections and future turnout systems to create:

• Circular loops

• Oval layouts

• Point-to-point operations

• Mining branches

• Expandable modular railroads
