I'm wondering why there seem to be no photos of any of the Southern's TrainMasters.
Southern's Train Masters were used as booster units between F7s and, later, SD 24s on the Rat Hole Division (Chattanooga to Cincinnati) and, in this capacity, had relatively undistinguished careers. This might account for the few photos available. Just my .02 worth.
