In a little over a year, the EMC E1 (a new and improved streamlined locomotive) would be pulling the "Super Chief" and other passenger consists, resplendent in the now-famous "Warbonnet" paint scheme devised by Leland Knickerbocker of the GM Art and Color Section. Its design was protected under a U.S. design patent, granted on November 9, 1937. It is reminiscent of a Native American ceremonial headdress. The scheme consisted of a red "bonnet" which wrapped around the front of the unit and was bordered by a yellow stripe and black pinstripe. The extent of the bonnet varied according to the locomotive model, and was largely determined by the shape and length of the carbody. The remainder of the unit was either painted silver or was composed of stainless-steel panels.
