In the whole game TSW 2, but mostly in the Great Western Express (mostly by using the "Class 166 GWG") a sound glitch appears that fastly repeats a short sequenze of the engine sounds and creates a tremolo. Sometimes the speakers also create hard click-sounds. It appears after some short, but mostly random time periods while driving fast, slow or standing at a station. It dissapears by changing the camera (outside/inside) or after some random time (... guess if the sound effect changes itself. Changing speed with the trains helps to remove the glitch). In the mentioned area [Great Western Express] with the mentioned train [Class 166 GWG], it appears realy ofter: impossible to drive from one small station to the next one without hitting this bug. But (less frequentet) it [this glitch] also appears in other areas in other trains. One time it appeared (also in the Great Western Express) by using the "Class 08 BLU" while standing outside during coupling waggons; another time in the "ACS-64 V AMTK" in Boston Sprinter. It [TSW 2] is a realy good game, I put a lot of money into it; and I would do this even more. (Thinking about go on 100% with all DLCs - Why not?! ... well, yes ... there is a reason. Vide supra [/see above]. :/ Hope this maximal annoying glitch will be fixed soon, so I can buy everything and have fun (without the problem that this glitch ruins the pleasure again (and again)).
You would be better posting on the TSW2 Forums rather than this which is for Train Simulator 2022 https://forums.dovetailgames.com/forums/technical-reports.80/

I did not say I was upset - I just wondered why you bothered posting the same info? Nothing much to do in Wales then
