In a method for operating a switching hump yard, at least one value for an entry speed into a first retarder is ascertained for the respective cuts in the form of rolling cars or car groups for the first retarder on the basis of a target release speed from the first retarder. At least one value for a release speed from a second retarder that lies uphill relative to the first retarder is determined for the second retarder on the basis of the ascertained at least one value for the entry speed into the first retarder. The second retarder is controlled taking into account the determined at least one value for the release speed. I also describe a control device for controlling a hump yard.
