Play on Linux, Windows, Mac, Android
It doesn’t matter which operating system you are using. Libre Train Sim works on Linux, Windows, Mac, and Android. Please note, the Android version has fewer features and lower-scaled graphics.
Small tutorials teach all the important topics to drive trains. If you don’t want to drive at all, there is even an autopilot.
If you are into the challenge, you can disable the easy mode enabling more complicated train systems.
