Union Pacific ES44AC No. 5401 gets lettered, striped and “Scotchlited” inside the paint shop at the Downing B. Jenks Shop at North Little Rock, Arkansas, on May 18, 2015. Skilled workers like Carman Gary Dunlap carefully apply the flag decals seen on the side of UP’s newer locomotives. After application of each piece, he will go over the segments and burnish out bubbles and other minor surface imperfections that commonly show up with this process. With the massive size of a locomotive, one can easily overlook that the large Scotchlite flags have to be tediously cut to each engineroom door and around other impediments like hinges and latches.
