I have bought this issue up at an earlier date, I have used timetable services on preserved collection route HRR WITH THE DB BR 146.2 and my experience is as follows, when I get up to track speed the game often skips causing significant audio skipping, its highly annoying when this keeps happening, it was a greater experience with tsw 2020 in my opinion, please tell me if anyone else has had this issue. Update I have used the br146.2 and the 185.5 on the Aachen Koln route and the game still skips, what I have found is there is a problem with the preserved collection, all the TSW2 Rolling stock works perfectly, there needs to be an investigation on this, when the skipping starts it leads to a whole plethora of bad game experiences, I hope the that Dovetail looks into this.
This error has already been reported. It is listed on the road map in the "planned" section. I'm waiting for a fix. https://live.dovetailgames.com/live/train-sim-world/articles/article/tsw2-roadmap-13-oct
