Two EMD SD70Ms wait for work at Union Pacific’s Downing B. Jenks Shop in North Little Rock, Arkansas, on May 19, 2015. No. 5090 has the “standard” SD70M cab, while sister No. 5155 is equipped with a so-called Phase II cab with the same windshields, but has a nose with sharper features and a raised center portion accommodating a full-size door—a similar look that foretold the SD70ACe.
