History
The connection of the airport loop railway was approved by the Federal Government on 20 December 1989 as part of the decision to build the Cologne–Frankfurt high-speed rail line on its current alignment. The construction of the Airport Link began on 4 December 2000 at Porz-Wahn station

started or stopped at the airport station. This creates operational problems, as the airport station was planned as a through station only and no turning facilities were built. Since the station has limited facilities, the terminating ICE trains tookup platform space properly reserved for S-Bahn trains. As a result, two thirds of the S-Bahn trains operating towards Cologne must use the outer platform, with the low platforms designed in Germany for long-distance trains, twenty centimetres lower than appropriate for S-Bahn trains, thus creating a step between the platform and the carriage floor.
