History

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, remaining there until 1973.[1]

In 1978, No. 4466 was donated to California State Railroad Museum. In 1984, it was restored to service and pulled museum excursions. In 1986, 4466 ventured to Vancouver, British Columbia, to be part of Steam Expo '86.[2]

Since at least 1999, UP 4466 now resides in retirement, and is currently a static display at the California State Railroad Museum.
