Planning is underway on the development of a continuous double track line on the Bonn–Witterschlick section and the construction of four new stations: Bonn-Endenich Nord (at km 2.2), Bonn-Helmholtzstraße (km 4.4), Alfter-Impekoven (km 7.1, not at site of the former Witterschlick/Impekoven, which was at a peripheral location near federal highway 56, but at the level crossing near Oedekoven) and Rheinbach Römerkanal.
