Thanks Hunt, I will check this out.  To be honest, I am really just looking for the easiest connection to the Forney's non-proprietary electronics bay (read as PnP).   I like the Tsunami sound in my Bachmann G scale Climax and 3-truck Shay locos (that came with DCC Oonboard), so I though I'd stick with the Tsunami Soundtraxx brand.

Does anyone have experience in putting a Tsunami 1000 in Bachmann's G scale outside frame Forney?  Is this a simple as adding the board and plugging in a speaker?   I bought a G scale Climax (Demonstrator 3) w/ DCC-Sound on board?  Could I use the board and speaker that came with the Climax and interchange it with the Forney?  It appears to have a DRG&W 3-chime whistle option that would sound nice in the Forney.    Thanks.
