Union Pacific 4012, Steam locomotive at Steamtown National Historic Site, United States
Union Pacific 4012 is a tender locomotive displayed at Steamtown and was designed for operation in mountain regions. It features a distinctive wheel arrangement and underwent complete restoration work to present it as it appears today.
The locomotive was built in 1941 and carried freight for many years through the mountains between Wyoming and Utah. It was retired in 1962 as new technology replaced steam power.
This locomotive shows how steam engines connected the American West and moved people and goods across vast distances. It stands today as a symbol of those connections and reminds visitors how railways shaped the settlement of the region.
The locomotive stands outdoors at Steamtown and is easy to view when you visit the site. It makes for a worthwhile stop if you have interest in railroads and vintage machinery.
This locomotive was among the last of its kind and operated for over three decades. Its special design allowed it to haul heavy loads through difficult mountain terrain where other engines could not manage the work.
