The upgraded line Cologne-Düren (ABS 4) seen from the eastern end of the northern platform at Köln-Ehrenfeld on 2 September 2002. The tracks 3 and 4 in the middle are used for passenger trains, on the left is one track for freight trains. The old track on the right is used for the construction works. In the background where the red and the green arm are visible, concrete is put into the form to build the bridge above the Subbelrather street.
