Mercury was the name used by the New York Central Railroad for a family of daytime streamliner passenger trains operating between midwestern cities. The Mercury train sets were designed by the noted industrial designer Henry Dreyfuss, and are considered a prime example of Art Deco design. The success of the Mercury led to Dreyfuss getting the commission for the 1938 redesign of the NYC’s flagship, the 20th Century Limited, perhaps the most famous train in America.

#4006 Chicago & North Western streamlined Class E4 4-6-4. The nine engines in this class were built to pull the C&NW "400". The train was dieselized before the E4's were delivered. They served in other capacities until 1953, their streamlining intact.

Following the success of streamline Mercury trains*, the New York Central decided to launch all-new trainsets on its Chicago line. 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 the New York Central).
