The SD-60 varied little from its predecessor visually, the main changes taking place internally with the aging 645F engine being replaced by the 710G. The two locomotives can be distinguished by the door panels; the SD-50 features four latched doors in six door panels whereas the SD-60 has six latched doors in eight door panels.

The "wide nose" or "safety cab" was first offered as an option to US railroads in 1988. Union Pacific received the first units in early 1989. In 1991, the contour of the nose was changed slightly, going from a 3-piece to 2-piece windshield and tapering the sides of the nose to improve visibility for the crew. Burlington Northern was the first recipient of the revised model.
