S19 (Rhine-Ruhr S-Bahn)

Line S19 is a S-Bahn line of the network in Germany. It is the youngest line in that network. It is operated by DB Regio with class 423 electric multiple units. The S19 runs until the early evening from Düren via Cologne to Blankenberg (Sieg), Herchen or Au (Sieg) on working days and between Düren and Hennef (Sieg) on Saturdays, Sundays and public holidays. Services to/from Herchen or Au do not stop in Blankenberg. It shares most of this route with line S12, but it runs through Cologne/Bonn Airport instead of through Porz. The S12 also no longer runs west of Horrem. It is operated every 20 minutes between Düren and Hennef (Sieg), with one course every hour extending to Au (Sieg). Since December 2019 it runs 24/7 between Düren and Hennef. rdf:langString
