Im trying to fix that problem. Engine blueprint was missing both <BogieAudioControlName> and <CouplingAudioControlName>. But adding those did not fix the problem, still no bogies sound. What else should I look for, any hints?
There's a patch that claims to add bogie sounds on Train Sim Community: https://www.trainsimcommunity.com/m...-patches/i6507-clinchfield-ge-u36c-loco-fixes it's by a poster with the same ID as you!
