Editing Union Pacific Railroad (section)

====Commemorative color schemes====
From the second half of 2005 to the summer of 2006, UP unveiled a new set of six [[EMD SD70ACe]] locomotives in "Heritage Colors", painted in schemes reminiscent of railroads acquired by the Union Pacific Corporation since the 1980s. The engine numbers match the year that the predecessor railroad became part of the Union Pacific system. The locomotives commemorate the [[Missouri Pacific Railroad|Missouri Pacific]] with [[Union Pacific 1982|UP 1982]], the [[Western Pacific Railroad|Western Pacific]] with [[Union Pacific 1983|UP 1983]], the [[Missouri–Kansas–Texas Railroad|Missouri–Kansas–Texas]] with [[Union Pacific 1988|UP 1988]], the [[Chicago and North Western Railway|Chicago and North Western]] with [[Union Pacific 1995|UP 1995]], the [[Southern Pacific Railroad|Southern Pacific]] with [[Union Pacific 1996|UP 1996]], and the [[Denver and Rio Grande Western Railroad|Denver and Rio Grande Western]] with [[Union Pacific 1989|UP 1989]].<ref>{{Cite press release |title=Denver & Rio Grande Western Colors Again Ride the Rails |date=June 19, 2006 |publisher=Union Pacific Railroad |url=http://www.uprr.com/newsinfo/releases/heritage_and_steam/2006/0619_drgw.shtml |access-date=April 20, 2010}}</ref>
