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 a “standard” SD70M cab, while slightly newer 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 EMD’s SD70ACe.
