Bahnhof Köln-Dellbrück

On 1 June 1882 the station passed to the Kingdom of Prussia when the Bergisch-Märkische Eisenbahn-Gesellschaft was nationalised. During an air raid on the night of 22–23 August 1943, the roof structure of the station building was badly damaged. In 1979 the old building was demolished and replaced with a functional building in the style of the time.

The S-Bahn stops at two electrified through tracks: at a side platform on track 1 and an island platform between tracks 2 and 3. The platforms are staggered and face each other directly over only a good 120 metres. Because of the platform height, step-free boarding into the Class 423 multiple units is not possible. North of the platform towards Cologne lies another electrified platform track, which passengers can use over 210 metres. Just under 500 metres to the east, a single-track section begins and continues to Bergisch Gladbach.

The S 11 runs every 20 minutes Monday to Saturday and every 30 minutes on Sundays. The RB 24 (Eifel-Bahn), which otherwise runs between Kall, Euskirchen and Köln-Deutz, uses the additional platform track: a single morning service is extended to Dellbrück on school days and returns from here to Köln Hbf. Freight trains of Häfen und Güterverkehr Köln (HGK) pass through the station on their way to the Bergisch Gladbach freight yard. Passengers can change to three bus routes: line 154 of the Kölner Verkehrs-Betriebe and lines 435 and 436 of Wupsi. Two of these connect to light rail lines 3 and 18 at the Dellbrück Hauptstraße stop. Regular buses to Köln-Dünnwald, Köln-Porz and Bergisch Gladbach depart from the small bus station south of the westbound platform, which leads to the bus bays without any change in level.
