Sound for Trainmaster?

[caliban]

Hi,

I've got an ATLAS TRAINMASTER in SP's bloody nose livery as birthday present from my wife today. It's a silverline model and just great, now I'm going to get some matching Gallery Cars. But this Trainmaster is so silent, what will be the best way to give him a voice. I really love this huge loco.
I added a few pictures, three generations of San Francisco commuter service.

I think Sound Traxx makes their sound systems from actual recordings of prototype locomotives. I don't know if they offer a Fairbanks-Morse Trainmaster specific sound chip.
