ilwaukee Road No. 5057 is a GE U25B locomotive that was built by General Electric for the Chicago, Milwaukee, St. Paul and Pacific Railway (or better known as the Milwaukee Road) in 1965. It is one of the twelve examples of the Milwaukee Road's GE U25B locomotives, which they had classified as the class "25-GRS". No. 5057 was delivered to the railway right after it was constructed.
