Download free Open Rails routes, trains and mods, find UK route packages, and install MSTS-compatible content with the correct dependencies.
Download the free Open Rails simulator for Windows from the official source linked in our free train simulator download guide, then obtain routes, trains and mods separately. Open Rails does not include Microsoft Train Simulator’s commercial routes, rolling stock or default assets, so check every add-on’s dependencies before installing it.
Open Rails download for PC: simulator or content?
The Open Rails download for PC supplies the simulation engine; routes, locomotives, wagons and activities are separate content. Install the official Windows build before downloading add-ons, and keep its application files separate from your train-simulation content.
Open Rails can use the established Microsoft Train Simulator folder structure, which is why searches for an “MSTS Open Rails download” often return two different things: the free Open Rails program and MSTS-compatible content for it. A route archive is not a substitute for the simulator, and installing Open Rails does not grant access to commercial MSTS files.
Open Rails routes free download
You can browse our free MSTS-compatible route downloads for content that can often be used in Open Rails. Compatible files are commonly categorised as MSTS routes because they use Microsoft Train Simulator’s route, track and rolling-stock formats, even when people now run them primarily in Open Rails.
Before downloading a route, check the description and included instructions for:
- Package type: choose a complete route when starting from scratch. An update, patch, activity pack or scenery extension requires an earlier route release.
- Freeware status: the route itself may be freeware while still requiring commercial MSTS assets or another base route that cannot be redistributed with it.
- Track and scenery dependencies: look for shared track systems, road packages, common scenery libraries and specific versions of global track files.
- Required trains: a route may load without the locomotives and coaches referenced by its activities, but those activities will not run correctly.
- Included content: establish whether the archive contains only the route, or also provides rolling stock, consists and at least one activity.
A file-library listing that says “Open Rails compatible” is helpful, but it is not proof that the download is standalone. The package instructions and dependency list are the deciding evidence.
Open Rails UK routes
UK and British route listings in our MSTS library can be used with Open Rails when their required track, scenery and train assets are present. British legacy routes are especially likely to rely on shared components installed outside the individual route folder.
- UK track systems: some routes use UK FineScale or another third-party track system. They may also require a compatible global track database such as
tsection.dat. - Shared route assets: bridges, platforms, roads and scenery may come from a common library or an earlier version of the route.
- Default MSTS files: older routes sometimes copy shapes, textures, terrain or sounds from the commercial simulator’s default routes. Open Rails does not supply those files.
- Supplied rolling stock: confirm whether the download includes the locomotives and coaches shown in its activities. Stock listed in screenshots is not necessarily part of the package.
Back up GLOBAL before allowing a legacy installer to replace shared track files. A mistake we see constantly is an old route installer overwriting a working global file with an earlier copy, after which unrelated routes stop loading. If two route collections require conflicting shared files, place them in separate Open Rails content roots or profiles rather than forcing both into one installation.
Open Rails mods: what does each download add?
Open Rails mods include routes, powered vehicles, rolling stock and the supporting files that assemble them into playable services. Our guide to MSTS route and train add-on categories explains where these packages are found and why their dependencies matter.
| Mod type | What it contains | Common dependency |
|---|---|---|
| Route | Track, terrain, scenery, paths and route configuration | Shared track systems, global assets or default MSTS files |
| Locomotive | A powered vehicle, normally defined by an .eng file | Separate cabview, sounds, textures or a base model |
| Rolling stock | Coaches, wagons and unpowered vehicles, commonly using .wag files | Shared textures, shapes or coupler settings |
| Consist | A selectable train formation stored in a .con file | Every locomotive, coach and wagon named in that consist |
| Activity | A scenario with a player service, traffic, paths and timetable instructions | The exact route, consists, paths, services and vehicles specified by its author |
| Cabview | The driving position, controls and cab graphics | The locomotive configuration must reference the correct cab files |
| Sound pack | Engine, horn, track and vehicle audio, usually controlled by sound scripts | Correct script paths and all referenced audio files |
These mods are not necessarily standalone. A repaint may provide only replacement textures, a locomotive may borrow another train’s cab and sounds, and an activity may require several separately downloaded consists.
What should a new Open Rails user download first?
Start with a complete, explicitly self-contained route package that lists its required stock and provides a working consist. Test the route without a dependency-heavy activity where that option is available, then add individual locomotives, coaches and activities once the basic content root works.
If you already own MSTS, you can instead create a profile for its existing content folder. Back it up before adding older packages, particularly anything that modifies GLOBAL or established train folders.
Why are Open Rails routes usually labelled MSTS?
Open Rails was designed to read much of the content created for Microsoft Train Simulator. Conventional route definitions, consists, locomotive and wagon files therefore retain their original MSTS formats and folder structure.
This compatibility is broad, not automatic. Old installers may expect a registered MSTS installation, activities reference exact file names, and some add-ons use undocumented scripts or assets that are absent from a clean Open Rails content root.
Can every MSTS route download run in Open Rails?
No. A conventional MSTS route is a good candidate, but it still needs every track section, shape, texture and train referenced by its files. Content designed around an old installer or a particular version of shared assets may need manual correction before Open Rails can load it.
Check the Open Rails log rather than assuming that an MSTS label guarantees compatibility. The first missing or invalid file is usually the useful error; later messages may simply be consequences of that initial failure.
How do I install MSTS routes and trains in Open Rails?
Open Rails manages routes and trains through configured content folders or profiles. The content root is the folder above GLOBAL, ROUTES and TRAINS, not the ROUTES folder itself.
- Install Open Rails. Put the simulator application in its normal Windows location and launch it once. Do not unpack route and train archives into the application directory.
- Create or select a content root. Use an existing MSTS folder or prepare a separate folder for MSTS-style content. Its conventional structure contains
GLOBAL,ROUTESandTRAINS. - Add the root in Open Rails. Use the simulator’s content-folder or profile management controls to register that root, then make sure the intended profile is selected.
- Extract the package without adding extra folder levels. If the archive starts with
ROUTESandTRAINS, merge those folders into the content root. If it contains only a named route folder, place that folder insideROUTES. - Install every dependency into the same content root. Add required track systems, scenery, trains, cabviews and sounds before testing. Dependencies stored under a different profile do not satisfy the route that needs them.
- Verify the route and consist. Select the profile, route and a valid consist, then start a short session. Check that the chosen route and consist are recorded in the Open Rails log and resolve the first missing-file or track-database error shown there.
Locomotives and wagons normally belong under TRAINS\TRAINSET\StockName, while consists belong under TRAINS\CONSISTS. Activities, paths, services and traffic files belong in their corresponding subfolders inside ROUTES\RouteName.
A route folder should contain its route definition rather than another identically named folder. Paths such as ROUTES\ROUTES\RouteName and TRAINSET\TRAINSET\StockName indicate that the archive was extracted one level too deep.
Why does a downloaded route or train not appear?
The symptom usually identifies which part of the content chain is broken.
| Symptom | Likely cause | What to check |
|---|---|---|
| Nothing from the package appears | Wrong profile, wrong root or nested folders | Confirm which content root Open Rails is reading and inspect the extraction path |
| Route is missing | Incomplete route folder or absent route definition | Check that the named folder sits directly under ROUTES and contains its route files |
| Locomotive is installed but cannot be selected | No valid consist | Install or create a .con file referencing that locomotive and its attached stock |
| Route works but an activity fails | Missing consist, service, traffic or path | Read the activity’s stock list and repair the first missing reference in the log |
| Track database will not load | Missing track shapes or incompatible global track data | Install the route’s stated track system and required shared files without blindly replacing newer assets |
| Cab, sound, shape or texture errors occur | Borrowed files were not installed | Trace the first missing .cvf, .sms, .wav, .s or .ace reference |
| An installer cannot find MSTS | Legacy installer expects an MSTS registry entry or fixed path | Read its instructions and extract manually when the archive permits it; do not point it at the Open Rails application folder |
Avoid fixing errors by copying unrelated files between train folders. That can hide one missing reference while creating incorrect sounds, cabs or textures elsewhere. Repair the named dependency or correct the reference at its source.
Do I need Microsoft Train Simulator installed?
You do not need MSTS for a genuinely self-contained Open Rails route and train package. You do need lawfully obtained MSTS files when a legacy add-on depends on the commercial simulator’s default routes, scenery, cabviews, sounds or shared assets.
Freeware describes the add-on’s distribution licence, not necessarily all of its prerequisites. Open Rails replaces the simulation engine; it does not replace or redistribute commercial Microsoft Train Simulator content referenced by older routes and trains.
