Pullman porters were men hired to work on the railroads as porters on sleeping cars. Starting shortly after the American Civil War, George Pullman sought out former slaves to work on his sleeper cars. Their job was to carry passengers’ baggage, shine shoes, set up and maintain the sleeping berths, and serve passengers. Pullman porters served American railroads from the late 1860s until the Pullman Company ceased operations on December 31, 1968, though some sleeping-car porters continued working on cars operated by the railroads themselves and, beginning in 1971, Amtrak. The term "porter" has been superseded in modern American usage by "sleeping car attendant", with the former term being considered "somewhat derogatory".
