Mainline Railworks On3 Straight Track

Mainline Railworks On3 Straight Track is designed specifically for On3 modelers who want reliable operation and authentic three-foot narrow gauge appearance in O scale. Whether you're constructing a compact switching layout, building a busy yard, or expanding a permanent mountain railroad, these precision straight sections provide the foundation for smooth operation and realistic trackwork.

All straight track sections are sold individually, allowing you to build the exact track plan your railroad requires.

🚂 Designed for On3

On3 combines the impressive size and detail of O scale with the distinctive character of three-foot narrow gauge railroading. That combination makes realistic track proportions especially important when building a detailed On3 railroad.

Mainline Railworks On3 track is purpose-built to complement O scale narrow gauge equipment, with realistic tie proportions, spacing, and track details that help capture the appearance of a true narrow gauge railroad. The result is track that provides both dependable operation and a convincing foundation for your On3 layout.

🚂 Why This Matters

Straight sections do far more than connect curves. They establish station tracks, passing sidings, yards, industries, and switching areas while making future layout expansion simple and predictable.

With individually sold sections, you can build your track plan one piece at a time and add additional straight sections whenever your railroad grows.
