That’s an EMD SD70ACe. That particular engine is the Rio Grande paint job that is part of Union Pacific’s heritage fleet. A SD70ACe was painted in the colors of the 6 major railroads that they bought (CNW, SP, MP, WP, MKT, & DRGW). Overland’s Tower 55 will produce models of each engine during this year sometime.
It does look A LOT like a “Phase II” SD90MAC-H, but it’s not. It’s a SD70ACe. EMD’s new Teir 2 AC unit. As far as I know no company currently makes a model of it in any scale. However if anyone does make it, it will most likely be Overland. They make a model of the new GE ES series locos. so it would make since that they would make this one also.
Kato makes the SD90MAC and they also make a SD70MAC but Tower 55 is the only company to announce the SD70ACe. http://www.tower55products.com/showroom.php (Click on UP Heritage Series).
Kato makes a SD43/90MAc, but the picture shows a SD70Ace. Tower 55 is coming out with a plastic version that is a few months away and a brass version that is overpriced at about $990 each. The brass version does not have sound, but if you pay for it, you probably can’r afford sound anymore.
The loco is EMD’s SD70Ace and only Tower 55 makes them in HO scale and currently Tower 55 hasn’t indicated if they will release the models in UP’s Heritage schemes. The only one announced is UP 4141 Air Force
