UP 4023
Title:  UP 4023
Description:  Union Pacific 4023 rolls through Evanston with a train. 4023 would be the sole survivor of the second batch of Big Boys. It was placed on display at the Omaha shops until they closed, at which time it was moved to its current home at Kenefick Park in Omaha, along with DDA40X 6900. Kenefick Park was named after UP chairman John Cooper "Mr. K" Kenefick, who also worked for the New York Central after serving in the Navy. Note the Union Pacific "Serves All The West" hopper in the background. Obtained from Union Pacific Steam: Big Boy Portraits (Bush, Ehernberger)
