Recent Events

In December 2020 the S13 got fully replaced by the S19, which was extending some courses of the S13 at the time. On workdays and Saturdays the S12 and S19 form a 10 minute interval between Köln-Ehrenfeld and Hennef and a 30 minute interval between Hennef and Au (Sieg). However, the S13 will be reintroduced after constructing the extension of the railway between Troisdorf and Bonn-Beuel (– Bonn Oberkassel) which is likely going to happen in 2025. The S13 will operate separately from the S19 between Bonn-Beuel and Düren in a 20 minute interval. The S19 will operate between Au (Sieg) and Köln Nippes every 20 minutes, offering nine courses in each direction between Troisdorf and Cologne (S12: 3 courses, S13: 3 courses, S19: 3 courses).
