$32.70 plus the extra fare of $9.60, plus the Pullman charge (e.g. $9 for a lower berth), for a total of $51.30, equal to $ today. This fare entitled a passenger to a bed closed off from the aisle by curtains; a compartment to oneself cost more. In 1928, the peak year, the train earned revenue of $10 million and was believed to be the most profitable train in the world. The cars of the 20th Century Limited were lit with fluorescent lamps soon after their introduction, which coincided with the introduction of the new Art Deco train sets on June 15, 1938. New train sets In 1938, industrial designer Henry Dreyfuss was commissioned by the New York Central to design streamlined train sets in Art Deco style, with the locomotive and passenger cars rendered in blues and grays (the colors of NYC). The streamlined sets were inaugurated on June 15, 1938. His design was probably the most famous American passenger train. The first new 20th Century Limited train left New York City at 18:00 Eastern Time and arrived at Chicago's La Salle Street Station the following morning at 09:00 Central Time, traveling the at an average . The eastbound train left La Salle Street Station in Chicago at 15:00 and arrived at Grand Central Terminal the following morning at 08:00. For a few years after World War II, the eastward schedule was shortened to 15½ hours. In 1945, EMD diesel-electrics replaced steam, and two new diesel-electric-powered trainsets were commissioned. The replacement was inaugurated by General Dwight D. Eisenhower in September, 1948. This set was featured in postwar films such as North by Northwest and The Band Wagon. Like many express passenger trains through the mid-1960s, the 20th Century Limited carried an East Division (E.D.) Railway Post Office (R.P.O.) car operated by the Railway Mail Service (RMS) of the United States Post Office Department which was staffed by USPOD clerks as a "fast mail" on each of its daily runs. The mails received by, postmarked, processed, sorted and dispatched from the 20th Century Limited RPOs were either canceled or backstamped (as appropriate) during the trip by hand-applied circular date stamps (CDS) reading "N.Y. & CHI.

For much of its history before 1957, the all-Pullman train made station stops only at Grand Central Terminal and Harmon for New
