Question - Is Toy Trains Unlimited still in business?

[HO Scale Model Railroader]

 For some time now, I've been toying with the idea of building the D-27 "Disappearing" Lionel Dealer Layout.  I knew TTU made an officially licensed reproduction - but they don't seem to be around anymore?  At least their website is gone.  Anyone know what happened to TTU?

I believe TTU sold the "new smoke pellets" portion of their business, at least,  to:

              www.trainz.com

 I know  nothing more about them.

As for the disappearing train layout, if you want to build it you can doubtless find the plans. Here is one source:
