They are missing. Try out the AC4400CW in any timetable scenario. The freight car sounds are missing. It's like a silent train.The only thing you hear is the slack taken up in the couplers at startup and a very muted rail joint sound in the distance. All other previous immersive sounds, as the freight cars rolled down the tracks are missing. The sounds are present when using the other locomotives. Why are they missing with the AC4400CW? How come nobody else has noticed this? DTG created another bug with an update. Who knows how long it will take before they fix this.
