Postcard photo of the streamliner City of Los Angeles near Sterling, Illinois and traveling along the Rock River. The train is pulled by a EMC E2 locomotive. The City of Los Angeles was a streamlined passenger train between Chicago, Illinois, and Los Angeles, California via Omaha, Nebraska, and Ogden, Utah. Between Omaha and Los Angeles it ran on the Union Pacific Railroad; east of Omaha it ran on the Chicago and North Western Railway until October 1955 and on the Milwaukee Road thereafter. This train was the top-of-the-line for the Union Pacific, which marketed it as a competitor to the Super Chief, a streamlined passenger train on the Atchison, Topeka and Santa Fe Railway, and the Golden State, a streamlined passenger train jointly operated by the Rock Island and Southern Pacific railroads. As with the City of Los Angeles, many of the train’s cars bore the names of locales in and around its namesake city. Circa late 1940s.
