Can you download Microsoft Train Simulator for free on PC? Get the legal answer, safe alternatives, Open Rails details and add-on compatibility.
No. The original Microsoft Train Simulator (MSTS) is discontinued commercial software, not legal freeware, so there is no authorised free full-game download for PC. If you own legitimate installation media, you may install that copy; otherwise, use Open Rails, a free simulator supporting suitable free content and compatible MSTS files you lawfully own.
Is Microsoft Train Simulator legally free?
Microsoft Train Simulator was released as a paid PC game, and its discontinuation did not turn it into freeware. “Abandonware” is an informal label, not a licence that permits somebody to distribute the game.
Files advertised as a full MSTS ISO, portable edition or pre-installed download are therefore not legitimate merely because the original boxed game is old. They may also contain modified executables or unwanted software. Our guide to obtaining train simulators from authorised sources explains the checks to make before downloading anything.
What is the closest free alternative to MSTS?
Open Rails is the closest free alternative for a PC user interested in Microsoft Train Simulator-era routes and rolling stock. It is a separate open-source simulator, not a free edition of MSTS and not a Microsoft product.
| Option | Free? | What it requires |
|---|---|---|
| Original Microsoft Train Simulator | No authorised full-game download | Legitimate installation media and its original files |
| Open Rails simulator | Yes | Open Rails-compatible content, supplied separately |
| MSTS route or train add-on | Often | The stated base simulator, assets and dependencies |
Open Rails can run many routes and trains made for MSTS, but it does not make copyrighted Microsoft assets free. Some community packages are self-contained; others require the default MSTS routes, global files, sounds or shared rolling stock. We cover setup and content profiles in our practical Open Rails installation instructions.
If you want a complete simulator rather than an MSTS-compatible engine, compare the best genuinely free train simulators for PC.
Can I use my original MSTS discs on a modern PC?
You can install Microsoft Train Simulator from legitimate discs you own, although the original program is not guaranteed to work cleanly on every modern Windows system. Its old installer, legacy disc checks, permissions and graphics assumptions can cause problems that do not affect Open Rails.
- Install from your own media. If the installer offers a destination choice, a simple user-writable folder can avoid some problems caused by protected system directories.
- Keep the MSTS content tree intact. Folders such as
GLOBAL,ROUTESandTRAINSare interdependent; copying a route alone is often insufficient. - Use Open Rails when the original executable fails. Point an Open Rails content profile at the valid MSTS installation folder rather than downloading a replacement executable.
- Apply compatibility settings only when needed. Do not fix missing-file or launch errors by collecting loose DLL or EXE files from unverified archives.
Why won’t a free MSTS download run?
Many files described casually as “Microsoft Train Simulator downloads” are add-ons, not the complete simulator. Check the documentation and required platform before extracting anything.
- MSTS add-ons may depend on default Microsoft routes, shared consists, cab views, sounds or global track files.
- Open Rails packages may be standalone, but only when the author has included or identified every permitted dependency.
- Train Simulator Classic content belongs to a different simulator and cannot simply be installed into MSTS or Open Rails. Our explanation of free add-on safety and platform compatibility covers this commonly confused distinction.
The safe choices are straightforward: retain and use a legitimate MSTS copy if you already own one, or install Open Rails with content explicitly licensed for free distribution. A discontinued title advertised as a free full-game download should not be treated as authorised without a clear licence from the rights holder.
