HO Scale Buildings & Structures – 3D Printed Buildings
These HO scale buildings and industrial structures are designed to bring realism and purpose to your model railroad scenes. From factories and utility buildings to industrial infrastructure, each model is 3D printed with crisp detail and built for easy painting and weathering.
Why These Models Work on Real Layouts
These HO scale structures are ideal for modern and transitional-era layouts, industrial districts, yards, and lineside scenes. Models are designed for seamless integration into operating layouts while maintaining accurate proportions and surface detail.
Designed for:
- All layouts that need some non rail focus, including switching layouts and industrial scenes
- Mainline freight operations
- Yards, sidings, and interchange scenes
- Display and photography

- Compatible with both modern and older rolling stock
Most designs are available in other scales — check individual product listings for details.
Used on Real Layouts
Many of the models offered here are used on the Trenton Model Railway, where they’re tested in real operating sessions and industrial scenes. Seeing how a model looks in context helps guide both design and refinement.
You can see these items in use on real layouts via the Building Trenton project.
