Union Pacific 4466 is an 0-6-0 type steam locomotive built in October 1920 for the Union Pacific Railroad (UP) to perform switching chores and transfer runs. 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] it was donated to California State Railroad Museum in 1978. 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] 4466 now resides in retirement. It has been sold to the Niles Canyon Railroad to be restored to service. As of 2016, the locomotive is at the California State Railroad Museum, in two pieces, preparing to be shipped by truck.
