摘要： In a locomotive having a dynamic braking capability, a method for maintaining an airflow path to a resistive grid disposed within a resistive grid enclosure having an enclosure inlet and an enclosure outlet is provided, wherein the method includes generating an inlet airflow into the enclosure inlet, creating a heated inlet airflow by associating the inlet airflow with the resistive grid such that the inlet airflow absorbs heat generated by the resistive grid, directing the heated inlet airflow toward the enclosure outlet to generate a heated outlet airflow, redirecting at least a portion of the heated outlet airflow to be thermally associated with a structural portion of the enclosure inlet such that the temperature of the structural portion of the enclosure inlet is increased above a predetermined temperature to reduce blockage of the enclosure inlet by snow and recirculating the redirected heated outlet airflow with ambient air being drawn into the resistive grid enclosure.

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.

摘要： A resistive grid enclosure for a vehicle having a dynamic braking capability, the grid enclosure defining an air inlet, an air outlet, and an airflow path through the enclosure from the air inlet to the air outlet. A resistive grid disposed within the enclosure is cooled by air flowing through the airflow path from the air inlet to the air outlet. The airflow path is configured so that an inlet airflow is heated by absorbing heat from the resistive grid and directed toward the air outlet forming a heated outlet airflow. The airflow path is further configured to direct at least a portion of the heated outlet airflow into the air inlet to reduce blockage of the air inlet by ice or snow.
