Union Pacific No. 4420

The Union Pacific No. 4420 is a Class S-4 0-6-0 steam locomotive. It was built in 1914 by the Lima Locomotive Works for the Union Pacific Railroad (UP). It was designed to work as a switcher for the UP for most of its career.
The engine was retired from service in 1957 and was then donated to the City of Evanston, WY in 1958. It was originally plighted on the courthouse lawn but was later moved to a new display spot in a play area off Elm Street a few yards north of Oak Street in Evanston, WY. 
It was revealed that Roundhouse Restoration INC, the company in charge of restoring the former Union Pacific Evanston Roundhouse and complex, had plans to move the 4420 to the Evanston Roundhouse, and eventually restore it to operation; the locomotive has since moved to be restored as of 15 July 2021.www.steamengine4420.org
The 4420 restoration is now about two years old (9-3-2013). It will take another two to three years and an estimated $200,000 to complete. There are still major parts to be restored and many components to replace. Four or five volunteers work on her every Tuesday and Thursday mornings. Everyone is welcome to come visit the engine while they are working on her at the Evanston Roundhouse. 
==Trivia==
*4420 is the oldest surviving Union Pacific S class 0-6-0.
*The 0-6-0 dominated switching duties in US railroads right up to WWI, although increasingly heavy freight loads had already brought more orders for 0-8-0 switchers.
*At the same time, old road engines were often diverted to switching, either as-built or after their leading and trailing trucks had been removed. Then, after WWI, the success of the USRA 0-8-0 design resulted in a reduction in demand for 0-6-0 switchers.
*Although orders did continue right into the 1940s, 0-6-0s were generally used on lighter duties and in smaller yards.
