What it does.

Track Designer is a desktop application for planning Märklin layouts. It snaps real catalog pieces together with millimetre precision, renders them in 3D with proper elevation, and exports parts lists you can take straight to the shop.

Real Catalog

165+ pieces from Märklin C, K, Z and TRIX C series, with accurate geometry, lengths and radii drawn from manufacturer catalogs.

Snap Engine

Drag a piece toward an open endpoint and it locks in with the correct heading. Series-aware: K-track won't connect to C-track without an adapter.

Elevation & Grades

Build ramps, viaducts and grade chains. Pieces tilt at their actual angle in 3D, with bridge supports rendered to scale.

3D Visualization

OpenGL viewer with orbit, pan and zoom. See your layout from any angle before you commit to wood and ballast.

Parts List

Live tally of every catalog number in your layout, with totals for motors and decoders auto-computed from your turnouts.

One-Click Buy

Send the entire parts list to your shopping cart at euromodeltrains.com with one click. Motors and decoders included automatically.

Levels & Layers

Multi-level support for staging yards, hidden track, and stacked loops. Toggle visibility per level while you work.

Library Blocks

Save any selection as a reusable block. Drop sidings, loops and yards into new layouts without rebuilding them piece by piece.

— 02 / In Use

What it looks like.

Built for designers who want precision without the spreadsheet. The 2D canvas keeps you fast; the 3D viewer keeps you honest about clearances and grades.

— 03 / Requirements

What it needs.

Track Designer is a native Windows desktop application. It runs on modest hardware — no GPU dedicated to gaming required, but a discrete graphics card helps the 3D viewer at scale.

FAQ.

If you don't see your question here, write to us at info@euromodeltrains.com — we read every message.

Is it really free?
Yes. No account, no subscription, no in-app purchases, no telemetry. The application is funded by our model train shop — if you like it and want to support us, the easiest way is to use the built-in Buy Track button when you're ready to build.
Which track systems are supported?
Märklin C-Track (HO), Märklin K-Track (HO), Märklin Z-Track (Mini-Club), and TRIX C-Track (HO). Adapter pieces between compatible series are included where Märklin produces them.
Does it run on Mac or Linux?
Not natively. Track Designer is a Windows application built with wxWidgets and OpenGL. Mac and Linux users have reported success running it under Wine and CrossOver, but we don't officially support those configurations.
Can I export to Rocrail or other layout software?
Track Designer saves layouts as XML and writes Rocrail-compatible plan files for the operational side (blocks, sensors, switches, routes). Geometry interchange with other CAD-style track designers is on the roadmap.
My antivirus flagged the installer. Why?
The installer is unsigned for v1.0 — code signing certificates are expensive for free software. Heuristic detection sometimes flags unsigned executables. The installer is built by us from open source. If you'd rather not trust us, you can scan it with VirusTotal before running.
How do I report a bug or request a feature?
Email us at info@euromodeltrains.com with a description of what you were doing and, if possible, the saved layout file. Screenshots help. We respond to every report.
Will my layouts still open in future versions?
Yes. The XML layout format is versioned and we commit to backward-compatible reads forever. If we ever need to change the format, the application will silently upgrade old files on save.
