UP 4466 spent most of its career in Cheyenne, Wyoming, as a shop switcher and was the UP Cheyenne Shop's last steam shop switcher. After its stint in Cheyenne, 4466 was transferred to Grand Island, Nebraska in 1960. The locomotive was retired from revenue service in July 1962.[1] It continued to remain in Grand Island until 1973 when it was donated to the Railway and Locomotive Historical Society.[2]
