Union Pacific has been running double-stack container trains over Donner Pass since November of 2009. Here, UP's 7802 West is, above, heading downhill on the #1 track at Dutch Flat where the speed limit is 25 mph.
On point, 7802 is what UP calls a General Electric C45ACCTE, which means a locomotive with AC-driven traction motors, 4400 hp, with CTE indicating "controlled tractive effort." 7802 is one of 325 such GE units purchased by UP and built between 2007 and 2008. GE refers to this model as the Evolution Series, ES44AC, which possesses the GEVO 12-cylinder diesel engine as prime mover.
Fifth photo down, UP 7802 West passes directly under Interstate 80 near Secret Town. On both point photos you can clearly see snow on the pilot. Click to enlarge each photo. Click on the post title for a GE Evolution brochure in PDF.
