View onto the upgraded line Cologne-Düren (ABS 4) looking towards east from the eastern access to the temporary platform at the station of Buir on 23 August 2001. In the center is the northern highspeed track, no ballast was put onto it by now. A lot of ballast was put onto the southern highspeed track. Next to the old line on the right is a new signal and the old entrance signal. The train far in the background runs on a section of the northern highspeed track that is already in service.
