to under an hour. Various improvements had been made to the line, including the eliminating of all crossings and the modernisation of all stations. A radio-based train protection system was installed. A timetable change in May 2006 raised speeds largely to 200 km/h on the upgraded section of the line between Bitterfeld and Leipzig. The upgrade of the Berlin–Bitterfeld–Leipzig line allowed the operation of ICE T tilting trains on IC line 8 from December 2002. In 2005 and 2006, the line from Bitterfeld to Leipzig was upgraded for operations of up to 200 km/h. A total of €1.657 billion was invested in the upgrade of line between Halle, Leipzig and Berlin up to the end of 2013. A curve directly connecting Leipzig/Halle Airport and the line to the north towards Berlin was contemplated but rejected in 2010. The Elbe floods of 2002 significantly damaged an already weakened section of the bridge over the Mulde between Roßlau and Dessau. Subsequently the embankment and all the bridges were rebuilt from 2008 to 2011 just to the east of the old line and the old works were then dismantled. Subsequently since 2009 there has been a comprehensive renovation, including a major reconstruction of the track and overhead line equipment of the Roßlau/Dessau railway node. The first section rebuilt covered the line from Dessau to Wolfen, including work to renew and adapt the stations of Dessau-Süd, Marke, Raguhn, Jeßnitz and Wolfen. On 5 December 2010, electronic interlockings were put into operation in Dessau and Raguhn, which replaced all other signal boxes on the section between Dessau and Wolfen. Between the spring of 2012 and the summer of 2013, further work was carried out on the section between Güterglück and Roßlau. Here, the second track was restored between Neeken and Roßlau, Zerbst and Rodleben stations were rebuilt and the overhead contact lines and the signalling systems were renewed. An electronic interlocking for this section of line was built in Güterglück. The remodelling of Roßlau station is planned. Between early 2010 and mid-2013, alterations were carried out between Leipzig Messe and Leipzig Hauptbahnhof for the integration of the Leipzig City Tunnel in place of the existing route. In this context, the new Leipzig Nord (planning name: Theresienstraße) station at Berliner Bridge was brought into operation at the end of 2013 together with the City Tunnel. The route to Bitterfeld was integrated into the network of the
