Locomotives in various stages of overhaul work line the north transfer table at the railroad’s Downing B. Jenks Shop in North Little Rock, Arkansas, on May 19, 2015, while a recently rebuilt Union Pacific SD40N No. 1783 rides the table to a new location at the shop. The former EMD SD40-2 has gone through an extensive rebuild program and is being moved by a Rail King RK 300 mobile railcar mover (trackmobile) that is used to move locomotives around the shop complex.
