The central signalling centre was brought into operation on 11 October 1964 at 4 AM. The new signal box controlled 295 sets of points and 446 signals and detected occupancy on 300 sections of track and seven automatic block sections. In the signalling centre there were four interlockings, one controlling the Holzkirchen wing station, two controlling the tracks of the main hall and the other one controlling the Starnberg wing station. The new interlockings needed only 38 staff for operations and 12 for maintaining the signal technology, saving 93 jobs.
