Dragon Railway
The world's largest collection of 3D printed model trains.
What Is It
An Open Ecosystem
The Dragon Railway is an open-source 3D printable model railway ecosystem in S-scale (1/64). A highly detailed and accurate scale model of a railway system - complete with locomotives, wagons, tracks, control systems, and accessories. Every major component is designed to be printed on a standard FDM printer.
Fully 3D Printed
As we say - "If it can be 3D printed, it will be 3D printed." From the body and wheels to the couplers, every major component is 3D printed. The only additional parts you need are screws, bearings, O-rings, and electronics. That's it.
Also Available in G-Scale (1/32)
Dragon Railway isn't limited to S-scale. The ecosystem also supports G-scale (1/32) - larger, bolder, and perfect for outdoor or garden railways. Dedicated bogies, couplers, and track components are available for G-scale.
Our Journey
Chasing a childhood dream
Years of iterations, One unstoppable goal
HO Scale Origins
Dragon Railway first started as an HO scale project. We wanted to build a fully 3D printed railway system, but after extensive testing, we concluded it was too unreliable on FDM printers. So we pivoted to 1/64 scale - and everything clicked.
The original HO scale designs are still available: GitHub repository
First Release
Dragon Railway V1 launched as a fully open-source 3D printed model railway system. Locomotives, wagons, a unique parametric track design, and an autocoupler system - all printable at home. The collection has steadily grown into the largest 3D printed model train ecosystem available today.
Expanding the Fleet
V2 built on the foundation of V1 by expanding the range of models available. More locomotives, more wagons, more track configurations - most open source with the same collaborative spirit that made V1 successful.

Community
Built by Makers, for Makers
Dragon Railway thrives because of its community. People remix, create, and share their own designs - expanding the ecosystem beyond what we could build alone.
Support the Project
If you find this project interesting, please share it with your friends and anyone who might like it. The sustainability of Dragon Railway relies on community engagement - more people means more ideas, feedback, and resources.
A thriving community ensures we can keep delivering new models, updates, and enhancements - making Dragon Railway a lasting resource for model train makers around the globe.
