1. A combined track conditioning unit for a rail vehicle, the combined track conditioning unit comprising:
a combined dispensing apparatus having a front region, a rear region, at least one outlet opening disposed centrally relative to a transverse direction of the rail vehicle and two outlet openings disposed laterally relative to the transverse direction of the rail vehicle, said two laterally-disposed outlet openings disposed upstream of said at least one centrally-disposed outlet opening in a travel direction of the rail vehicle and all of said outlet openings having a location in said front region for applying a gaseous drying medium to a rail, and a gritting material outlet unit having a location in said rear region for applying a gritting material to the rail;
said at least one centrally disposed outflow opening being configured for drying when traveling straight ahead, and said at least one centrally-disposed outlet opening including a plurality of centrally disposed outflow openings disposed on a rotary plate for drying when traveling straight ahead;
said two laterally-disposed outlet openings and said at least one centrally-disposed outlet opening being simultaneously and separately operable in dependence on conditions of the rail;
said locations of said outflow opening and said gritting material outlet unit causing a portion of a track being traveled over to be initially dried, to then have the gritting material applied to it and to finally be traveled over by a wheel of the rail vehicle with an increased adhesion value between the wheel and the rail.
