Upgraded line Cologne-Düren (ABS 4), view towards west from km 24.6 on 15 July 2001. The new overtaking station Dorsfeld can be seen in the background. The northern highspeed track is finished and is used for trains towards Düren, while the other is still under construction. Trains to Cologne use the single track for the S-Bahn (urban trains) which is on the left.
