A sand stairway for a sand-spreading system of a rail vehicle has a stairway housing with a sand compartment for providing sliding spreading sand. A blow-out duct discharges spreading sand from the stairway housing. First and second nozzle inserts are releasably inserted into first and second receiving holes of a nozzle flange of the stairway housing above the sand compartment. The nozzle inserts are produced separately from the stairway housing. The first nozzle insert produces an air jet directed into the sand compartment and swirls up spreading sand. The second nozzle insert produces an air jet directed into the blow-out duct and swirls up spreading sand. A sand-spreading system for a rail vehicle has a sand stairway for the compressed-air-controlled metering of the discharged spreading sand. The novel sand stairway has increased flexibility and can be set up without great effort for using different types of spreading sand.
