Abstract
A method for operating a switching hump yard, wherein in a first operating mode a lower master retarder is controlled in such a manner that cuts in the form of descending cars or groups of cars reach a classification track retarder of a classification track at a speed that is lower than a first threshold, a switch is made from the first operating mode into a second operating mode if a target for a cut is found in or in front of the classification track retarder of the classification track, and in the second operating mode the master retarder is controlled in such a manner that the cut reaches the determined target in or in front of the classification track retarder at a speed that is lower than a second threshold. We also describe a controller for controlling such a switching hump yard.
