View onto the upgraded line Cologne-Düren (ABS 4) looking towards east from the pedestrian bridge at the station of Königsdorf on 15 August 2001. In the center the street to Cologne (Aachener Straße) crosses the railway. The tracks for the S-Bahn (urban trains) on the right are finished and by this time used for all trains. In the area for the highspeed tracks on the left, the work on the wall is under progress.
