摘要： A control assembly includes a monitoring module and a switching module. The monitoring module determines a load demand of a first rail vehicle traveling along a track, wherein the first rail vehicle is supplied with electric current from a plurality of power sources over a conductive pathway extending along the track. The switching module is communicatively coupled with the monitoring module and is joined with a switch controller disposed between the power sources and the conductive pathway. The switching module directs the switch controller to change which of the power sources supply the electric current to the first rail vehicle over the conductive pathway based on the load demand.
