The upgraded line Cologne-Düren (ABS 4) seen from the access to the temporary station of Sindorf on 23 July 2001 looking east towards Horrem. In the background a section of the southern highspeed track is already visible. Even the temporary pedestrian bridge at the station of Horrem can be recognized, it is about 3 km away. The old line is on the right.
