The upgraded line Cologne-Düren
(<a href="http://www-users.rwth-aachen.de/christoph.schmitz2/strecke/strecke.html">ABS 4</a>)
seen from a point between Horrem and Sindorf, looking east on 29 August 2001.
The southern highspeed track is filled up with ballast and tamped. The old line
is on the right.
