Union Pacific CA-4 Caboose #25103 CA-4 CaboosesBetween 1942 and 1975, 750 steel cabooses were delivered to the Union Pacific. Easily identified by a tall cupola centered on the roof, these Union Pacific CA-class cabooses are one of the most recognizable caboose types in North America. The CA-4 class, built at Pullman Standard's Michigan City plant in 1944, featured riveted body panels, Murphy roof panels, a small lavatory window, and "Q"-style trucks when first delivered. The general design and basic features of the unique high-cupola caboose of Union Pacific, however, remained unchanged for over 30 years.
