I agree that the horn should stand out more, but I actually disagree with the less loud engine noise. The ES44AC is a powerful diesel locomotive, and in real life those GE engines are loud—especially under load. Having the engine and even more the horn dominate the soundscape is more realistic. I don't think the engine should be turned down. In fact regarding most diesel locomotives in the game, the volume of the engine especially under load as well as the horn should be amplified The sounds that in my opinion have to be taken down a little are traction motor / inverter sounds in most electric trains
