ABSTRACT:
An empty/load valve brake control device for a railway vehicle includes a body and a valve member disposed within the body. The body defines an inlet passageway, an outlet passageway, an exhaust passageway, and a secondary passageway. The valve member has an empty position, a load position, and a partial load position. The inlet passageway is connected to the outlet passageway when the valve member is in the empty position, the outlet passageway is connected to the exhaust passageway when the valve member is in the load position, and the inlet passageway is connected to the secondary passageway when the valve member is in the partial load position.
