 In the course of renovation a secondary hump with shorter sorting and formation sidings ("Nachordnungsgleisen") will be given up in favour of longer sorting sidings for the formation of long-distance trains.Reception and sorting sidings and their associated points will be replaced in sets and the hump technology will be upgraded to the latest state of the art as part of the renovation work on the whole yard.A total of 220 million euros is being invested in this work which should be completed by 2014.
