Found the following in an online article about the Carolina and North Western and their one-and-only RS-11:
Conductor Bob Gantt remembers that Number 11 was a "real hoss when it came to pulling tonnage, especially on the grades between Hickory and Granite Falls." However, as a road-switcher, "it was pretty poor, because the engineers couldn't ease from a dead stop to an easy push. The operation of the engine wasn't smooth at all and tended to be all herky-jerky."
Clearly, it would have benefited from Command Control.
