UP 4005

UP 4005 is one of the 25 4000 class "Big Boy" locomotives that were built. She was built by the American Locomotive in 1941. She was the only big boy that was converted to oil as an experiment. She was involved in a major wreck in 1953 that killed member of the crew and some live stock. In said wreck, she damaged her tender. She is on static display at the Forney Museum of Transportation until August 16, 2019.
