What specs and storage does Train Simulator Classic need?
Train Simulator Classic needs a 64-bit Windows PC, 4 GB of RAM, a Core i3-4330/FX-6300-class processor, a GTX 750 Ti/R9 270-class graphics card and 40 GB of free storage at minimum. For a route-heavy installation, we recommend an SSD, 16 GB of RAM and substantially more free space.
Train Simulator Classic minimum and recommended PC specs
The published baseline is modest, but the recommended specification is a safer floor for detailed routes, busy scenarios and higher graphics settings. Requirements have been carried across several annual editions, so older listings may differ slightly in how they describe Windows support.
| Component | Published minimum | Published recommended | Our practical target |
|---|---|---|---|
| Operating system | 64-bit Windows; older specifications may name Windows 8.1 | 64-bit Windows 10 | Windows 11 for a new PC; existing Windows 10 installations can run it |
| Processor | Intel Core i3-4330 at 3.5 GHz or AMD FX-6300 at 3.5 GHz | Intel Core i5-4690K at 3.5 GHz or AMD Ryzen 5 1500X at 3.7 GHz | A modern processor with strong per-core performance |
| Memory | 4 GB RAM | 8 GB RAM | 16 GB RAM for complex routes, add-ons and background applications |
| Graphics | GeForce GTX 750 Ti or Radeon R9 270 with 1 GB VRAM | GeForce GTX 970 or Radeon RX 480 with 4 GB VRAM | A dedicated GPU with at least 4 GB VRAM |
| DirectX | DirectX 9.0c compatible | DirectX 9.0c compatible | A modern GPU able to run the legacy DirectX components installed with the simulator |
| Storage | 40 GB available | 40 GB available | SSD with extra space for routes, rolling stock, mods and Steam updates |
The named processors and graphics cards are comparison points, not parts you must buy. A newer component is suitable when its performance meets or exceeds the listed model. Train Simulator Classic is a Windows PC simulator; it has no native macOS or console edition.
Is 40 GB enough for Train Simulator Classic?
Forty gigabytes is enough only as the official starting allowance, not as a realistic limit for an expanding installation. The exact installed size depends on which edition or bundle you own because different packages include different routes and rolling stock.
Storage use grows through:
- Additional route and locomotive DLC, including shared scenery and rolling-stock assets.
- Workshop scenarios and the routes or trains those scenarios require.
- Manually installed freeware placed in the
AssetsandContentfolders. - Route-building projects, source files and personal backups.
A 100 GB allocation is a sensible starting budget if you expect to install several extra routes. Large collections can occupy several hundred gigabytes, so there is no useful single figure for a fully expanded library.
Steam may also need temporary working space while downloading or replacing packaged route files. A mistake we see constantly is leaving exactly 40 GB free, then finding that an update fails even though the installed simulator appears to fit. Keep additional headroom rather than filling the drive to its limit.
Where are the Train Simulator Classic files stored?
The default game directory is normally Steam\steamapps\common\RailWorks, although a custom Steam library can place it on another drive. Steam's Properties > Installed Files screen identifies the active location and reports the main application's storage use.
Do not remove random folders from Assets or Content to recover space. Routes and scenarios often share dependencies, so deleting what appears to be an unused asset can break another route or produce missing scenery and rolling stock. Use Steam's storage controls to move the installation, and follow our safe process for installing and managing Train Simulator Classic mods when adding third-party files.
Which hardware upgrades make the biggest difference?
A faster CPU and an SSD usually improve the experience more consistently than buying an oversized graphics card for this simulator alone. Train Simulator Classic uses a long-developed engine whose performance can be constrained by per-core processor speed, route scripting and the number of assets being loaded.
- Processor: Strong per-core performance helps with busy stations, AI traffic and complicated scenarios. More cores alone do not guarantee smoother running.
- SSD: An SSD shortens loading and can reduce pauses while scenery assets are read from storage, although it cannot eliminate every engine-related stutter.
- Memory: The simulator can meet its published requirement with 4 GB, but 8 GB is the realistic minimum and 16 GB gives Windows and complex add-ons more breathing room.
- Graphics card: GPU demand rises with resolution, anti-aliasing, shadows and dense scenery. A powerful GPU cannot compensate fully for a CPU-limited route.

Can Train Simulator Classic run on a laptop?
Train Simulator Classic can run on a laptop if its sustained CPU and GPU performance is comparable to the desktop components above. Model names alone can mislead because mobile graphics chips and low-power processors may perform differently from similarly named desktop parts.
A laptop with only integrated graphics may launch the simulator, but it falls below the published dedicated-GPU baseline in many cases. Expect to reduce resolution, shadows, anti-aliasing and scenery settings, and keep the laptop connected to mains power so its performance profile does not throttle the processor or GPU.
