It looks like the Black Widown F7's got bumped from the Tsu1 to Tus2 list with the delay from Jan 17 to Jun 17. All the other Athearn loco's I wanted unfortunately were Tsu1 so with the exception of a 2 with old generation ST, I bought all of mine silent

Here's a list of Athearn locomotives that will/do have Tsunami2 sound decoders.

Athearn has published list of which announced loco's come with which decoders. I don't have the link handy but if someone can find it and post, you'll have your answers. I do know I was interested in the SP black widown Genesis F7's which were due Jan 2017 and they were listed with the old Tsu1 sound; the expected date has now been put off to next summer but I haven't checked to see if that means the sound decoder has changed.
Hello,
I want to think I remember reading somewhere that Athearn's switch to the Tsunami 2 was very soon. Does anyone have any idea if any of the latest releases like the new white face BN GP50 or Santa Fe GP39 2 have it? If not I wonder how much old OEM Athearn has left and if they will let us know which new releases have the 2?
ThanksSB
