There's no volume control that I'm aware of (if there was, I'd probably crank up the whistle and bell sounds). The whistle doesn't sound all that 'natural' to me but it sounds okay. Personally, I wish my ET&WNC ten-wheeler had a whistle sound more like the ones that RR used on their engines, but the factory one will do.
These are my first sound-equipped engines ever (all four of my Bachmann ten-wheelers have factory sound), and for the most part, I'm happy with how they sound.
