Lately, I've become more and more aware of the great variety of sounds not directly related to trains included in TSW: sirens and barking, for example, and perhaps moos and baas -- although those may just come from my imagination. Regardless of that, these sounds bring me more of what I frequently described here as "immersion". Thanks, TSW developers!
I agree. That was something noticeably lacking from RailWorks but implemented well in MSTS. Glad to see environment sounds making a comeback!
