outskirts of Leipzig and passes under federal highway 184 and autobahn 14. Near the Leipzig Trade Fair (Messe), the Erfurt–Leipzig/Halle high-speed railway approaches from the west. After Leipzig Messe station, the old line from Halle approaches from the same direction, together with the freight ring. The latter turns to the east at Eutritzsch towards Engelsdorf, while the line from Eilenburg comes from the same direction. After a slight change of direction to the southwest, the line reaches Leipzig Hauptbahnhof near to the centre of its many tracks. Infrastructure As part of the re-equipment with Punktförmige Zugbeeinflussung ("intermittent train protection”), the remaining semaphore and colour light signals were replaced. As part of the upgrading of the whole line to allow operations at 200 km/h between 1992 and 1999, it was equipped with electronic interlockings. Since then, continuous reversible operations have been possible as only Ks signals (Kombinationssignal), the most modern system of colour light signals in Germany, are used. All level crossings have been eliminated and replaced by new bridges. To test and adapt the new European standard signalling and control system, Deutsche Bahn installed European Train Control System (ETCS) Level 2 on part of this line for the first time in Germany. The 2418/2419 pair of Intercity trains operated on trial scheduled services equipped with ETCS at up to 200 km/h from 26 May 2006. On 17 June 2006, for the first time in Europe, a scheduled service, operated under ETCS, was recorded at 200 km/h. Operations Since 2006, there have been no long-distance trains north of Bitterfeld. In the current timetable (as of 15 December 2013) the following trains run: Regional services RB54 and RB86 overlap between Dessau and Bitterfeld and RB54 and RB57 overlap between Bitterfeld and Leipzig to give an hour service in Bitterfeld. The trains on line S2 of the S-Bahn Mitteldeutschland run hourly between Bitterfeld and Leipzig, but only between Delitzsch and Leipzig on weekends.
