***I edited the thread to become a repository of all videos of ULT prime mover files.****
In this thread you will find video recordings of Railpro's ULT prime mover files as they are heard from a model locomotive. Video recording is inherently limited in it's ability to capture how the model sounds when you are next to it. But these videos should give you an idea of what the prime mover files sound like.
