MODELRAILWAY.PT Modular Helix System Precision Engineering. Effortless Assembly. Ultimate Layout Flexibility.

Building a reliable helix is one of the biggest challenges in model railroading — but it doesn’t have to be. The MODELRAILWAY.PT Modular Helix System turns complex geometry into a smooth, plug-and-play experience. Laser-cut with extreme precision, our intuitive modular kits let you build a rock-solid multi-level helix tailored to your exact layout needs.

Why Choose Our Modular Helix?

• Fail-Safe Precision: Laser-cut 8mm and 10mm premium plywood with interlocking joins ensures perfect alignment every single lap.
• Smart Track Alignment: Pre-engraved markings for sleeper width and cork trackbed (+5mm margin) eliminate guesswork during installation.
• Maximum Traction Safety: Designed with ultra-smooth transitions and a maximum gradient of under 3.0% to keep your trains climbing safely without stall or derailment.
• Level-by-Level Assembly: Our smart vertical support system allows you to assemble level by level, making track laying, wiring, and testing effortless before adding the next lap.
• Fully Reversible: Every section and support can be rotated 180°, allowing seamless left-hand or right-hand ascent.
• Tool-Free Modular Clips: High-durability 3D-printed clips secure sections effortlessly while allowing quick adjustments whenever needed.
