Well, actually, I spent almost an hour looking for the info, and then another hour just trying to find out how to simply post the question.  (My life doesn't revolve around computers)  Seems like it should be basic info with the item listing, or at the very least one of the FAQs in the DCC section.

Ohhhhh, how I "love" webpage designers!

Do DCC equipped engines work with regular DC?  Seems like a very relevant question, but I can't find any info on it here.
