The western entrance signals of Düren (on Cologne-Aachen) seen on 23
February 2003. They belong to the
Ks
system. On the left track is signal "27 FF" and on the right is "27 F". On
the right of "27 F" is the track coming from Heimbach, it's signal is further
west and not in the picture. Both signals are combined signals and have a Zs3
(speed indicator) and a Zs3v (announcement of Zs3) each. The left track was
rebuilt that day, so the signal is protected by a fence.
