Does Soundtraxx make a Tsunami with doodlebug sounds?
If not then I'd go with something that has recordable sounds like QSI or Digitrax.

Has anyone installed a Tsunami sound decoder in a Bachmann Doodlebug? It now has the original "decoder" and all the wiring/lands problems have been taken care of. Just want to upgrade and spend more of the kids inheretance. My grandaughter loves the stupid thing and her birthday is in a couple of months...sooooooo. There's certainly enough room inside for a speaker. I thought I'd drape off the speaker area and "pull the blinds"
