And if you did update the controls, your new design is TERRIBLE. No RPM, can't go to neutral in the reverser, and every control is so different. I highly suggest y'all revert back to your old style as that is way better.
If you haven't fixed it yet, at the title screen, go to Settings > Gameplay > Train Controls, and change it form simplified to expert.
I honestly think the simple controls are worse than useless. Apart from the restrictions they place on you, which are just a nuisance, they're no simpler to use than the expert controls. If I could say one thing to anyone getting started in TS it'd be just jump in the deep end because it's actually no deeper than the shallow end.
That's why I don't understand people who use simplified controls. I've seen people on YouTube using them and they look so useless. It's like driving a model train!
