The connecting curve between the Leipzig-Dresden and Dresden-Elsterwerda routes on the upgraded Leipzig-Dresden line was upgraded between the Radebeul Zitzschewig junction and Radebeul-Nord junction. A grade separation structure was partially upgraded, a new split railroad overpass was built over Meissner Strasse, the railroad overpass over Lachenweg was widened, and two retaining walls and a noise barrier were built in addition to civil and underground engineering and work on the permanent way that was needed for the new track system. Overhead line equipment was also installed and the new Weinböhla electronic interlocking went into service.
The construction project is part of the German Unity Transport Project (VDE 9). The project has been laying the technical groundwork since 1998 to improve rail links between Saxony’s industrial area and industrial centers in Central and Western Germany.
In 2018, the Construction Supervision Unit of DB Engineering & Consulting (DB E&C) took on responsibility for ensuring that structural engineering work and work on the permanent way, overhead line equipment, 50 Hz electrical power systems, control-command and signaling, and telecommunications equipment was carried out according to plan, on time and in line with quality requirements. The Environment, Geotechnics and Survey Unit was responsible for geotechnical construction supervision.
DB E&C’s Inspection Center Unit handled acceptance testing for the fully upgraded overhead line equipment, 50 Hz electrical power systems and conversion of control-command and signaling to electronic interlocking technology, with DB Netz and DB Energie handling acceptance testing of one part.
