two power signal boxes (Befehlsstellwerk) of S&H type. An automatic track vacancy detection system was not installed. Two dispatchers direct operations using the Sächsischen Befehlsblocks (Saxon command block) system. An upgrade and adaptation of these systems in the course of the German Unity Transport Project (Verkehrsprojekts Deutsche Einheit) No. 9 has not been possible as the regulations could not have been complied with. Many jobs were lost in relation to signalling, control of points and train detection. Of the seven signal boxes, only signal box 1 on the eastern side has been retained as a memorial. A flyover taking the Görlitz–Dresden line over the Leipzig–Dresden line went into operation in 2007. During construction, two temporary platforms were erected outside the train shed as several platforms and tracks were not available. The rolling stock storage area next to track 1 will be dismantled during the remodeling of the tracks, . The operation on ten mainline tracks and two local tracks was converted from tracks arranged by direction of operation to being arranged by line. The southern platform (platforms 1 and 2) would be reserved for the future S-Bahn railway traffic while platform 3/4 would be reserved for regional traffic. The two northern platforms (platforms 5/6 and 7/8) are shared by long-distance and regional traffic. Nearby to the north there are two tracks for through trains, which were originally part of a connecting curve from the Leipzig-Dresden railway, connecting from the west in the southern approaches. Five bridges (some built in the style of the original construction of the station), 54 sets of points, two flying junctions and 101 metres of noise barrier (at Bischofsplatz) are being built. The running speed will be increased in the station area from 40 km/h or 60 km/h to 80 km/h throughout except at junctions on some route. Main line and S-Bahn services will be continuously separated. Two turnback tracks have been built for S-Bahn services. The total cost of the remodeling of the track layout, the renewal of the civil engineering works and the replacement of mechanical interlocking by electronic Interlocking is €95 million A total of €33 million has been budgeted for the reconstruction of the central part of the station, of which €14.4 million is for S-Bahn-projects. The construction of the 2.5 km long section was expected to take four years in mid-2006. The main works were completed at the end of 2014.
