I think I recall reading about this somewhere so apologies I couldn’t find the post. I keep getting random vibrations on the standard Xbox controller but couldn’t find any way to disable it. Incredibly annoying, just does it randomly while operating trains. Side note is the hud speedometer supposed to only go up to 100mph? thanks for any help!
The extra vibrations are likely caused by the values set in the "Control Settings" section of the settings menus. They include vibrations for operating levers, flicking switches etc. Just set any you don't want to a value of 0.
