EMD SW10 Switcher Union Pacific Gameplay - TS2016 PC HD

By the mid to late 1970s UP's switcher fleet had become very old by railroad standards, with the newest units, the 1953-built SW9s, being twenty years old. The in-service fleet was composed of NW2s, SW7s, SW9s and TR5s, all built between 1939 and 1953. It was apparent that either more low-horsepower road power, or new switch engines would soon be needed, or the old switchers would have to be remanufactured. Whichever path was chosen, the UP knew action would have to be taken to reduce the costs of failures and maintenance attributed to the old switchers. One of the directions taken during Frank D. Acord's tenure as UP's motive power chief from October 1971 until his retirement in June 1980, was to simplify the railroad's locomotive roster. That roster, all purchased while David S. Neuhart was General Superintendent of the railroad's Motive Power and Machinery Department from April 1949 to September 1971, included many "odd" and one-of-a-kind types of units, including the turbines, the 6900 class Centennials, and other double diesels. Frank Acord wanted to get the roster down to just a few standard models of locomotives. Another goal was to modernize the fleet. The motive power studies of the 1970s showed that UP still needed locomotives of the SW-type configuration, mostly for the urban yards and other industrialized locations. The railroad also wanted to reduce its numbers of four-axle locomotives and began a program to abandon branchlines and upgrade other branches to allow use of SD, six-axle locomotives. The form that the new switcher would take would be determined by five choices. First, the railroad could buy new locomotives, but at the time the builders were busy with C30-7s and SD40-2s, and the price paid for new switchers would be a premium one. Second, they could buy locomotives off of the used locomotive market, but that market was tight and expensive, and the available switchers were mostly the same type and age as the railroad's current fleet which they wanted to replace. Third, they could rebuild the units they needed themselves, from the fleet that they already owned. Fourth, the railroad could have its fleet rebuilt by an outside vendor, but the rebuild market hadn't yet reached the size and strength that it would later. Or fifth, they could do nothing, and delay the decision to a later time. Union Pacific chose to do a combination of the second and fifth choices, and rebuild their own, but only in small lots to spread out the cost. #Trains #Trainz #Trainsimulator
