Fun bits start at about 3:45.

Welcome to 2010. Saw it last year.

look at the A/C unit on the signal box at about 1:45. That's a neat detail to do.

That's a Carrier Air V. They were installed on RV's until they exited that market a few years ago. I've seen some offered in HO. The ones on the Atlas Genset are similar, but low-profile units.
Probably more than you wanted to know about them...

Terry, also started to see them on more and more main-line units. Gave me the idea to do this one.

I've got one on an SD38, though only a single a/c unit. In the real word, it does cut down a lot on heat-induced fatigue. I know I'd rather spend 12 hours in an air conditioned cab than 12 hours in a black-painted metal box. Your a/c units look pretty good.
