Two bridges of the upgraded line Cologne-Düren (ABS 4) crossing the Hornstraße in Cologne. The old one carries one track of the main line to Düren/Aachen (the other track is far away in the background) while the new one is built for the two tracks of the S-Bahn (urban trains). The S-Bahn line ascends from left to right to cross the main line. Of course the main line is electrified, but the catenary is hidden behind the new bridge. The S-Bahn will also be electrified before it is taken into service. Photo taken from the north side of the line on 30 June 2001.
