Pacific Harbor Line MP20B-3 20, seen switching autoracks in the railroad's Pier B Yard, was built by EMD as Denver & Rio Grande GP40 3079 in February 1979. When the Southern Pacific, which was acquired by the D&RGW (which elected to use the name of the larger SP for the new railroad) was merged with the Union Pacific, this locomotive became part of UP’s locomotive fleet, but it was never renumbered or repainted. UP retired it at the end of June 1999, and it was acquired by MotivePower Inc. of Boise ID and rebuilt into Pacific Harbor Line MP20B-3 20 in May 2008. (Long Beach, California – October 8, 2024)
