This DLC might be having a bit of a rocky start although excelent choice, there are some issues with the sound on my end. The cooling fans cut off and a classic sound bug is now affecting the coal cars on the german line that involves this 155. They are now quiet. I uploaded what the quiet wagon is in the report here. Just take the 155 if you purchased this and go to the timetable section and look for a coal hopper run, pick that, set up the loco so it runs, etc and then after a few seconds the coal freight car's sound just cuts off.
