Listening to all the available Sounds some would appear (to my ears) to be pretty good for European or UK use. Certainly the Chuffs if the Steam Dynamo and Bell can be controlled would all appear to be fine. Sadly the Bell is just too American in the way it rings. Far removed from the ones used on the HSB.Although the decoder is not loco specific you have the choice of various 'weights' of loco, chuff patterns etc etc.
Here is a screen shot of the sound options:
