In 1976, EMD completed an extensive four-year research program which investigated the wheel-rail, friction-creep relationship of a locomotive. In parallel with this program, a developmental program was initiated in 1973 to design a locomotive control system which would take advantage of the information and conclusions from the friction-creep study. In 1978 and 1979, EMD built 32 prototype locomotives with a new wheel control system. This control system, known as "Super Series," provides an increase of approximately 33 percent in utilization of available adhesion over conventional locomotive wheel slip systems. This paper presents the "Super Series" Wheel Control-System and how the system relates to and controls the series wound traction motor. Included is a brief discussion of the conclusions from the friction-creep study and how these conclusions became the design parameters for the "Super Series" system. Test and operational results taken from performance of the prototype locomotives are included.
