The photo is dated as circa 1940s. This type of locomotive went into service on the line circa 1938. These locomotives were scrapped in 1954. Since this was a train which operated as a partnership between two railroads, in 1955, the Union Pacific dropped its agreement with the North Western for the leg of the service between Chicago and Omaha, joining with the Chicago, Milwaukee and St. Paul Railway for it instead. The card has no Zip Code on it, which came into use circa mid 1960s.
