About
3D Train Studio — known in German as 3D-Modellbahn Studio — is a comprehensive model railway planning and simulation platform for Windows. Hobbyists and enthusiasts can design layouts using a library of more than 2,000 track pieces from well-known manufacturers, covering all common track gauges including indoor room layouts, garden railways, brick-style railways, and real-world track configurations. Beyond track planning, the software includes rich landscape-design tools to sculpt mountains, valleys, bodies of water, and vegetation, bringing miniature worlds to life with real-time 3D graphics. An online community catalog provides access to thousands of additional models — locomotives, wagons, vehicles, buildings, and scenery objects — contributed by other users. The simulation engine supports full railway operations: animated level crossings, signals, road vehicles, and automatic block sections. Users can control operations manually via a custom control panel or automate everything through event triggers and the built-in Lua scripting language. An open API enables integration with external control software such as Rocrail. The free Standard version covers core planning features with a cap of 150 models per layout and up to 3 elevation layers. The Professional tier (from €49.90) removes those limits, adds version-controlled backups, custom track systems, layout sharing, external program integration, and optional multi-user licensing for families. A Plus Package add-on extends Professional with further content and discounts on new releases. Ideal for model railway hobbyists, educators, and layout designers who want a powerful yet approachable tool for both planning and virtual operation of their railway layouts.
Key Features
- Extensive Track Library: Over 2,000 track pieces from leading manufacturers in all common gauges, enabling accurate scale planning for room layouts, garden railways, and real-world track configurations.
- Landscape & Scenery Design: Powerful terrain tools to sculpt mountains, valleys, rivers, and vegetation, plus an online community catalog with thousands of additional 3D models for buildings, vehicles, and more.
- Real-Time 3D Simulation: Watch trains run, level crossings close, and road vehicles respond to signals in real time, viewable from multiple 2D and 3D perspectives.
- Event Automation & Lua Scripting: Automate all railway operations through event-driven triggers or write custom scripts using the built-in Lua scripting language for full control over complex layouts.
- External Program API: Open API allows integration with external railway control software such as Rocrail, enabling advanced digital model railway control workflows.
Use Cases
- Planning detailed model railway layouts to scale before building the physical version, avoiding costly track-laying mistakes.
- Designing and visualizing complete miniature landscapes with terrain, vegetation, roads, and buildings in real-time 3D.
- Simulating and automating full railway operations — including block sections, signals, and level crossings — for realistic digital model railway experiences.
- Building and sharing complex railway layouts with the community through the online catalog and layout-sharing features.
- Integrating virtual layout control with external DCC software like Rocrail via the built-in API for advanced model railway automation.
Pros
- Free to Try: A fully functional Standard version is available at no cost, letting users explore core planning and simulation features before committing to a purchase.
- Large Community Catalog: The online catalog provides access to thousands of community-contributed 3D models, greatly expanding scenery and rolling-stock options beyond the built-in library.
- Powerful Automation: Lua scripting and an open API give advanced users deep control over automated operations and integration with external DCC control systems.
Cons
- Windows Only: The application is available exclusively for Windows 64-bit, leaving macOS and Linux users without a native option.
- Key Features Locked Behind Paywall: Important capabilities such as removing model/layer limits, sharing layouts, adding custom track systems, and using the external API require the paid Professional version.
- Primarily German Interface: The software and website are predominantly in German, which may present a language barrier for non-German-speaking users.
Frequently Asked Questions
Yes — the Standard version is completely free and includes core track planning, landscape design, and simulation features. The Professional version starts at €49.90 and unlocks advanced capabilities such as unlimited models, layout sharing, and the external API.
3D Train Studio runs on Windows 64-bit only. There is no macOS, Linux, or mobile version available at this time.
Yes, but this requires the Professional version. Professional users can import custom track systems and additional building components, and share their layouts with other users.
Yes. The software supports event-driven automation for all railway operations — including signals, level crossings, and block sections — and includes a Lua scripting engine for custom automation logic.
Yes. The Professional version includes an open API that allows integration with external programs such as Rocrail, enabling you to control your digital model railway layout from dedicated DCC software.
