I’ve noticed when spawning in on foot and riding as a passenger that the multi level coach cars are entirely too loud. It sounds like you’re riding through a wind tunnel. Also the Acelas interior sounds are spot on. The only issue that seems to be present with those is a minor spike in audio as it travels through an underpass. The amfleet coaches interior sounds are okay but could be tuned down just a bit more and made similar to the acelas interior sounds, as I have rode them on numberous occasions and the sounds on the flanges against the rails are a tad bit high as well. Side note: The passenger lighting or HEP is not on in the multilevel a.i coaches either. Haven’t tested out the others yet.
