If you want to go back a few years to the fastest freight that UP ever ran, the "Super Van", you would need the power to be two DD40X diesels spliced in the middle with a "Fast Forty" SD-40. Super Van was operated mostly as a UPS priority train but often carried a mixed bag of trailers. The power was geared for 90 mph running, but never got near that point, but 75 mph was common on long stretches of the route. This was UP's attempt to match SF's shorter Chgo to LA route with a train fast enough to make up the difference in the longer miles by pure speed. <br /> <br />Today's Zips carry the above mentioned company trailers, bulk containers, and a larger percentage of refrigerated trailers than in years past.
