Download and install a train simulator game on PC safely. Choose the right edition and drive, then fix launch errors and missing DLC.
To download and install a train simulator game on PC, choose the simulator, obtain it through its official PC distribution client or publisher installer, select an install drive with ample free space, let the download and prerequisite setup finish, then launch the base game before adding routes, trains or community content.
The exact process depends on the title. Train Sim World and Train Simulator Classic normally install through a PC distribution client, while Open Rails uses its own installer and requires separate compatible routes and rolling stock.
Which train simulator should I install?
Choose the simulator before downloading because the installation method, included content and add-on compatibility are different.
| Simulator | Choose it when | Installation route |
|---|---|---|
| Train Sim World | You want a modern, packaged simulator with routes and trains supplied as downloadable content. | Use our detailed Train Sim World installation steps. |
| Train Simulator Classic | You want its established catalogue of routes, locomotives and scenarios. | Follow our PC setup instructions for Train Simulator Classic. |
| Open Rails | You want a free Windows simulator and have, or plan to obtain, compatible route and rolling-stock content. | See how to install Open Rails and connect its content folders. |
Pay attention to editions and bundles. A cheaper package may contain the same base simulator but different routes, while an item labelled as a route, locomotive or expansion may be DLC rather than a game that runs by itself.
How to download and install a train simulator on Windows
- Check the PC requirements. Compare the simulator's stated Windows, processor, memory, graphics and storage requirements with your computer. The target drive and Windows system drive should both have spare space because installation can create temporary files.
- Select the PC edition. Confirm that the licence is for PC, not a console, and check which routes or train packs are included. Sign in with the account that owns the game.
- Use the official installer. Open the authorised PC client or publisher installer, add the game to your library and select its install command. Avoid unofficial repacks and installers from unknown download pages.
- Choose the install drive. An internal SSD is the best general choice. Use the client's library-folder controls rather than creating an improvised folder inside a cloud-synchronised directory.
- Let setup finish completely. A client may continue unpacking files or installing graphics and runtime components after the download reaches 100%. Do not force-close it during this stage, and restart Windows if setup requests it.
- Launch the base simulator once. Allow it to create configuration files, index installed content and complete any first-run checks. Test a supplied route before adding community files.
- Install additional content carefully. Enable purchased DLC through the client's content manager if necessary. Add third-party routes or rolling stock one package at a time and follow instructions written for that exact simulator.
Can I install a train simulator on another drive?
A train simulator can usually be installed on a secondary or external drive when its distribution client allows that location, but the drive must remain attached and retain enough free space for updates.
| Drive | When to use it | Main caveat |
|---|---|---|
| Secondary internal SSD | Best choice when the system SSD lacks capacity. | The client must be told which library folder to use. |
| External SSD | Useful for a laptop or a large DLC collection. | A disconnected drive can make the game appear uninstalled; use a stable connection and a Windows-compatible file system. |
| Hard disk drive | Acceptable when capacity matters more than loading speed. | Route loading and asset streaming may take longer. |
Do not move an installed game by dragging its folder in File Explorer. Use the client's built-in move or library-management function so that its installation records are updated correctly.
Why will the train simulator not install or launch?
Most failed installations come from insufficient temporary space, an account or edition mismatch, interrupted downloads, missing runtime components or a game folder moved outside the distribution client.
| Problem | What to check |
|---|---|
| Install button is unavailable | Confirm that the signed-in account owns the PC version and that the selected item is the base game rather than DLC. |
| Not enough disk space | Free space on both the destination and Windows drives. The final advertised size may not include temporary unpacking space or optional content. |
| Download stops or repeatedly restarts | Restart the client and PC, confirm the connection is stable, and use the client's repair or download-cache function if one is provided. |
| Game opens and immediately closes | Finish pending runtime installations, restart Windows, update the graphics driver and run the client's file-verification tool. Do not download individual DLL files from unknown sources. |
| Installed game is no longer detected | Reconnect the original drive, then use the client's locate, repair or library-detection option instead of downloading everything again. |
| Routes, trains or DLC are missing | Check that the content belongs to the same account and PC platform, is enabled for download and supports the installed base title. Some scenarios also require separately owned routes or rolling stock. |
| Open Rails shows no routes | The simulator program and its railway content are separate. Select a valid content profile containing compatible routes, consists and rolling stock. |
If security software flags an installer, first confirm that it came from the authorised source. Do not disable protection globally merely to force an unknown file to run.
What should I do after the first launch?
Run a supplied tutorial or simple scenario with the default controls before changing graphics settings or installing add-ons.
No specialist controller is required: a keyboard and mouse are enough to confirm that the game, route and cab controls work. Set the correct display resolution, choose a conservative graphics preset, and raise demanding settings gradually once performance is stable. Our beginner’s train-simulator setup guide explains the next steps after installation.
For community content, extract archives only when the included instructions say to do so, and place files in the simulator-specific add-on location rather than dropping every archive into the main game folder. A route may depend on separate scenery assets or rolling stock, so a successful installation does not guarantee that every downloaded scenario has all its dependencies.
