Force coupler was first introduced in the VL Niagara and basically replaces the manual operation of increasing/decreasing the chuff labor. The drawbar has a sensor that can tell when the locomotive is pulling a sizable load. Depending on the weight of the load determines how much labor the locomotive will produce.
