View onto the upgraded line Cologne-Düren (ABS 4) looking towards east from the street bridge near Merzenich on 23 August 2001. On the right are the new tracks for the S-Bahn (urban trains), they will be connected to the old line in the background. The highspeed tracks will use the place of the old line under the bridge and continue north of the old line in the background.
