NW-2's Phased Out?

[tsched]

I just noticed that the NW-2 engines aren't listed on the website anymore.  Has production on them been discontinued?  I love those little engines.  They're good soldiers on the layout

I do not believe they are totally out but I would think they will be back with the new sound system. I do have one on hold at my hobby store because they are hard to come by now. They are great engines as all the Williams engines. Just hold on and I bet they will be back.

Ditto what you said about the NW-2's Wm

I have 4 of them and would like to get a couple more in the future.

If they do have new sound systems will we be able to replace the ones we have now with the new systems.

I ave to confess after listening to what these sound systems are capable of I really like the sounds. The other option is I hope there is an on/off switch as there are times I just want to run the trains without any sound.
