The words SANTA FE were applied in yellow in a 5"–high extended font, and centered on the nose was the "Santa Fe" box logo (initially consisting of a blue cross, circle, and square painted on a solid bronze sheet, but subsequently changed to baked steel sheets painted bronze with the blue identifying elements applied on top). Three thin, pale yellow stripes (known as "Cat Whiskers") extended from the nose logo around the cab sides. In January, 1951, Santa Fe revised the scheme to consist of three yellow stripes running up the nose, with the addition of a blue and yellow "Cigar Band" (similar in size and shape to that applied to passenger units); the blue background and elongated yellow "SANTA FE" lettering were retained.
