In the late 1970s, UP was looking to replace their aging SW7, SW9 and TR5A switch engines, many of which dating to the late 1930s-50s. New switch locomotives were expensive so UP opted to rebuild their existing switchers at their Omaha Shops. In 1979, UP 1848 entered the shops and nearly every component was stripped. Trucks were overhauled and converted to roller bearings, sill handrails were added, and the frame was steam cleaned. The original EMD 567-power assemblies were swapped out for newer 645-assemblies. All-new cabling and wiring were added along with two new 36", electrically-driven cooling fans from retired GP9s, leading to a unique hood hump that makes these engines easy to spot. SW10's also received a new sand box on the nose and new MU cables. Finally the cab was updated to FRA-mandated "clean cab" standards with a new AAR control stand and refrigerator placed inside. A total of 75 units were rebuilt between 1979 and 1984. By the mid 90s, many of these units were sold off to other railroads. In 2017, UP donated SW10 96 (previously assigned to the steam program) to the Oregon Rail Heritage Center, where it operates today.
