Hey... I've decided against this mod, after using it for a while because it is to op for me.
How can I revert the braking force to a normal value? After unresearching the braking force 8-15 researches via console and uninstalling the mod, the trains still brake instantly.
Edit: if anyone needs an answer in the future:
/c game.player.force.train_braking_force_bonus = 1
where "1" is the level of braking force you want to apply (vanilla 1-7)
