Locomotives receive overhauls in the main shop building at Union Pacific’s Downing B. Jenks Shop at North Little Rock, Arkansas, on May 18, 2015. UP SD40-2 No. 3151 is being rebuilt into a SD40N, while behind it on the same track, EMD GP40-2 No. 1383 gets a thorough overhaul, which includes removing the telltale notch in the nose from its days as a Southern Pacific locomotive. On the left, GE ES44AC No. 7761 is being rebuilt, and in the foreground are hood assemblies, also known as “cabs,” from EMD SD70ACe No. 8382 that is having its prime mover replaced.
