Mainline Railworks On30 Straight Track

Mainline Railworks On30 Straight Track is designed specifically for On30 modelers who want both reliable operation and authentic narrow gauge appearance. Whether you're constructing a simple tabletop railroad, building a busy switching yard, or expanding a permanent layout, 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 On30

The right gauge is only half the story.

While On30 equipment runs on HO gauge track, most HO track is designed for standard gauge railroads. The smaller ties, tighter spacing, and narrower profile can look undersized beneath On30 locomotives and rolling stock.

Mainline Railworks On30 track is purpose-built for On30, featuring oversized ties, realistic spacing, and a wider track profile that better captures the appearance of real narrow gauge railroads. The result is a layout that not only operates reliably—but looks the way an On30 railroad should.

🚂 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.
