The station of Horrem on the upgraded line Cologne-Düren
(<a href="http://www-users.rwth-aachen.de/christoph.schmitz2/strecke/strecke.html">ABS 4</a>)
on 13 July 2001. Looking towards east onto the old line which will be upgraded
for the S-Bahn (urban trains) later. Several new Ks signals are visible. The
rightmost is a combined signal which will replace the distant signal next to
it, also covering the switch which is right next to the other signals. The one
in the middle will not replace an old one because the track is not equipped for
bidirectional traffic by now. The left one is for the new track 3, which will
be put into service sometimes after the new signals are operational.
