JMaurer1: I doubt that it would be popular enough for MT, if no one else has ever done one, or made decals for one. The scheme is actually very simple, and the same color as the Atlas FM, but I don't fell like spelling the name out with alphabet decals... Lazy, I know, but there are other cars I need more that the time could be spent on.
On the other hand, if Atlas is making the loco, they might make a boxcar to go with it. The cars I've found pictures of are AAR standard cars, so Intermountain would be the logical source, but given their (non)deliveries lately I won't hold my breath.
