To enable the TS Controllers app to communicate with TSW5, a Steam Launch option needs to be added manually one time.
- Open the Steam App
- Right click on Train Sim World 5, and select Properties

- When the properties window is open, ensure you are in the General Tab, and type -httpapi in the Launch Options text box.
If you already have launch options in there such as -DX12, just add it after that, so it would be: -DX12 -httpapi
The TS Controllers app, should now be able to control Train Sim World 5.
