During rush hour, the S12 gets extended to Horrem, so with the S19 six trains operate hourly in each direction between Cologne and Horrem. Services operates every 20 minutes on Saturdays and every 30 minutes on Sundays and public holidays. On Sundays and public holidays the S12 operates every 30 minutes between Horrem and Au (Sieg).
