An underrated feature in TS1, I find it very disappointing that TSW didn't include controller vibrations. Nothing was more immersive than having your controller vibrate every so often simulating track joints and the familiar "clack clack" sounds as your train rolled through it. There are settings in Engine.ini which hint to this, but I have tried all sorts of settings and controllers and have come to the conclusion that this just isn't implemented. Not sure if vibrations are in the console version, maybe someone can confirm for me. Hopefully this is planned in the future for PC release!
