E-8 No. 4059 heads one of the New York Central's crack trains, perhaps the Twentieth Century Limited, during its brief pause at Chicago's Englewood Union Station in July 1954. An unidentified EMD E-7 unit is trailing. Notice No. 4059's aluminum-painted trucks and other underbody parts; this treatment was NYC practice during the mid-to-late 1950s to render its passenger diesels more attractive to the public. The practice for other diesels was to paint these parts standard "locomotive black."
