A coke oven rail car with a drive control system for positioning the car and for spotting the functional equipment carried by the car. A sensor determines the relative position of the car with respect to a selected oven in a coke oven battery. The car includes a first drive for effecting gross movement of the car along the rails and gross positioning of the car relative to the selected oven. The car further includes a second automatically controlled drive for effecting fine movement of the car along the rails and fine positioning of the car relative to the selected oven. In one embodiment the first drive is manually controlled, while in another embodiment the first drive is automatically controlled. The second automatically controlled drive can take the form of one or two disk clutch type mechanisms or a clutch band type mechanism.
