Compare buying Train Simulator Classic on Steam or Just Trains, including Steam-key activation, add-on updates, mixed installs and reinstall risks.
Buy Train Simulator Classic itself on Steam unless a Just Trains package is cheaper or includes extras you want. A Just Trains copy is not a separate platform: where it is supplied as a Steam key, it still activates, installs and runs through Steam. For Just Trains’ own add-ons, buying direct often makes more sense.
Is the Just Trains version separate from Steam?
No. Train Simulator Classic uses Steam for the core game, library ownership, downloads and updates. If a Just Trains listing supplies a Steam key, you pay Just Trains but redeem the key on Steam; the resulting game uses the same RailWorks installation as a copy purchased inside Steam.
Read the exact product listing before paying. Confirm whether it is the base simulator, a bundle or an add-on, whether a Steam key is supplied, and which routes and locomotives are included. Packages can share similar names while containing different stock or scenarios. Our Steam installation and DLC checklist explains what happens after activation.
Steam versus Just Trains: which purchase suits you?
| Decision | Choose Steam | Choose Just Trains |
|---|---|---|
| Base simulator | Best for the simplest purchase, activation and installation. | Reasonable when the listing supplies a valid Steam key and offers a better bundle or price. |
| Add-on management | Steam DLC downloads automatically and appears in Steam's DLC manager. | Direct products normally use the publisher's installer and separate update process. |
| Reinstallation | Steam can reacquire owned Steam DLC with the core game. | You must retain account access and any licence details needed to reinstall direct products. |
| Just Trains-developed content | Convenient if that product is offered on Steam and you want one library. | Useful when you prefer the direct edition, its included content and the publisher's own support route. |
When comparing bundles, judge the included routes, rolling stock and prerequisites rather than the headline product name. Our guide to choosing worthwhile Train Simulator Classic routes and DLC can help identify content you would actually use.
Can Steam DLC and Just Trains add-ons be mixed?
Yes. Steam DLC and compatible Just Trains add-ons can normally coexist in the same Train Simulator Classic installation. The complication is management: Steam does not list, update or restore an add-on installed directly through Just Trains.
- Install every direct product into the active
steamapps/common/RailWorksfolder. A moved Steam library or an obsolete folder left by an earlier installation can cause the installer to choose the wrong location. - Check dependencies carefully. A Just Trains route or scenario may require separate Steam routes or rolling stock.
- Do not buy the same add-on twice unless you deliberately need a different edition. Steam and Just Trains generally do not recognise ownership from the other storefront.
- Do not assume identically named editions contain identical scenarios, stock or features; compare their contents line by line.
Missing trains, broken consists or absent scenery usually indicate an unmet dependency or an installer pointed at the wrong folder, not an inherent conflict between the two stores. Our explanation of Workshop content, manual add-ons and dependency handling covers the same issue for freeware and community files.
What happens when Train Simulator Classic is reinstalled?
Steam restores the core simulator and Steam-owned DLC, but it cannot restore products bought as direct-download add-ons.
- Install the core game first. Let Steam finish downloading Train Simulator Classic, then launch it once.
- Restore Steam DLC. Confirm the required routes and rolling stock are enabled and fully downloaded.
- Obtain fresh direct installers. Use the latest installers available in your Just Trains account and retain any licence information supplied with the purchase.
- Check the destination folder. Point each installer at the active
RailWorksdirectory, especially after moving the Steam library to another drive. - Reinstall dependent content last. Add scenarios, reskins and patches only after their parent routes and trains are present.
Which option should you choose?
For the base Train Simulator Classic package, Steam is the straightforward choice. Buying it from Just Trains is equally workable when the product is delivered as a Steam key and the bundle or price is preferable; there is no separate Just Trains platform or game installation to gain.
For Just Trains' own routes and rolling stock, buy direct when you are comfortable managing installers and updates separately. Choose the Steam edition when automatic downloads, centralised DLC management and easier reinstalls matter more. Mixing both is practical, but keep a record of which store supplied every add-on.
