Long Union Pacific loaded oil train coming down steep grade the Moffat Route

A loaded and very long Union Pacific oil train comes down the Moffat Route. The short (few hundred feet) 3% grade shown in the beginning of the video is the steepest part of the Moffat Route in Colorado. Oil trains were a rarity on this route but have made a big comeback recently on both the Union Pacific and BNSF. These are now daily trains. Union Pacific freight trains which were sporadic last year, are also increasing.
