I ended up picking up one of the black ones as a souvenir to my family's trip to Salt Lake City over Spring break. Although I had the one with the orange cupola in my hand first, but changed my mind and grabbed the black one. Knowing now that the orange cupola'd one was a switching platform for the SLC area, I wish I would have kept it now.
Aaaaaanyways. Question, Do the black ones have lighting? I've ran mine on my DCC layout, and don't see any lighting at all. I know it's not DCC, but I wasn't sure about any other lighting.
EDIT: I caved, found the website for the hobby shop that I got my caboose from, and ordered the orange cupola'd one also.
