Mainline Railworks HOn3 Turnout Switches are designed to help modelers create smooth-running narrow gauge railroads with reliable geometry and easy layout planning. Whether you are building a compact mountain line, a sharp mining branch, or a permanent layout, these premium turnout switches make HOn3 construction simpler and more enjoyable. Engineered as a direct drop-in replacement, each turnout switch can be substituted in place of any 19A curve section to seamlessly integrate into your existing track configuration.
🚂 Why This Matters
Consistent geometry is critical in narrow gauge modeling. These turnout switches provide flawless route divergence without disrupting your layout's footprint, reducing derailments and making expansion less frustrating—especially for new HOn3 modelers.
🏔 Perfect For
  • Compact shelf and tabletop railroads
  • Colorado-style narrow gauge routes
  • Mining and logging branch lines
  • Expanding permanent model layouts
  • Custom point-to-point operations
🔧 Key Features
  • Direct 19A Drop-In Replacement: Fits perfectly in the footprint of any standard 19A curve section.
  • Handcrafted Quality: Artisan hand-assembled switches built for supreme tracking precision.
  • HOn3 Narrow Gauge Track: Precision-engineered sectional switches for exact alignment.
  • Code 80 Rail Profile: Delivers reliable operation and broad equipment compatibility.
  • Precision-Matched Geometry: Guarantees smooth, derailment-free rolling stock transitions.
  • Easy-to-Connect Design: Visual and physical alignment matches standard HOn3 sectional tracks.
  • Industrial-Grade Reliability: Ideal for both beginner and experienced model railroaders.
🛠 Production & Lead Time
Every single turnout switch is meticulously made by hand to ensure the highest standard of operational reliability. To maintain this level of craftsmanship, all switches are manufactured on-demand and fulfilled strictly in the order received. Please allow an estimated 2–4 week lead time for build production and shipment prep.
⚙️ Compatibility
  • Substitutes perfectly into any layout designed for a 19A curve section.
  • Compatible with Mainline Railworks HOn3 sectional track systems.
  • Integrates with Mainline Railworks HO/HOn3 dual-gauge track components.
  • Designed for use with standard HOn3 locomotives and narrow gauge rolling stock.
  • Compatible with legacy Blackstone ProTraxx HOn3 sectional track geometry.
Pairs Well With
  • Mainline Railworks 19A Curve Track
  • Mainline Railworks Straight Track
  • Feeder Track Sections
⚠️ Builder Tip
Because these high-quality pieces are hand-crafted on-demand with a 2–4 week lead time, planning your track expansions ahead of time ensures your custom switches arrive right when your construction schedule needs them. [1]
📐 Turnout Geometry Options
Mainline Railworks HOn3 turnout switches utilize a specialized geometry that matches the exact curve radius and arc length of standard 19A curves, allowing modelers to create branching tracks without recalculating their layout spacing.
Available Orientation Options
  • Left-Hand Turnouts: Diverges to the left, replacing a standard left-hand 19A curve section.
  • Right-Hand Turnouts: Diverges to the right, replacing a standard right-hand 19A curve section.
🔄 Layout Flexibility
Because these switches match standard curve profiles, they can be mixed and matched with straight sections and curves to create:
  • Passing sidings and run-around tracks
  • Multi-track staging yards
  • Industrial spur switchbacks
  • Expandable sectional and modular railroads
