 This method allows the locomotives to be numbered into the Union Pacific's roster but is cheaper than fully repainting the engine into UP Armour Yellow.In 2006, Union Pacific unveiled UP 1989, an EMD SD70ACe painted in a stylized version of the DRGW color scheme.This unit is one of several SD70ACe locomotives the UP has painted in stylized colors to help preserve the image of the railroads it has merged; the others are Missouri Pacific Railroad, Missouri-Kansas-Texas Railroad, Chicago and North Western Railway, Southern Pacific Railroad, and Western Pacific Railroad.
