[1] The Stadtbahn station is on ground level just south of the line, enabling direct interchange.

According to the City of Cologne, this can only be done by establishing a parking garage since there are no more spaces available for expansion.

[5] The station was built before the 2006 FIFA World Cup to relief the Stadtbahn trains from RheinEnergie Stadion (part of line 1) to the center of Cologne.

During the peak, line S12 also provides services every 20 minutes between Horrem and Hennef (Sieg).
