After downloading the update, I found that on the Bakerloo Line, Schnellfahrstrecke Köln-Aachen, and the Arosa Line, there are no engine sounds inside the cabs. I can hear the engines in the outside views (2 and 3), but inside the cabs, I don't hear the slightest hum or whine, but just the sound of the fans, controls, tracks, rain, wipers, etc., and I don't believe that the cabs were isolated that good ... When I compare this with similar engines in TS 2021, the difference is quite clear. In that, the engine sound is softer inside the cab, but still recognizable. On the Sand Patch Grade, all diesels can be heard inside the cab.
