The two western entrance signals of the new overtaking station Dorsfeld (on Cologne-Aachen) seen on 13 October 2001. They belong to the Ks system. While the signals inside the station are always on the right side of the track, here the left signal is placed on the left side. Both have a Zs3 (speed indicator) for diverging entrance routes. Only the right signal has a Zs3v (announcement of Zs3), which is only used if the entrance route is straight, but the exit route is diverging. If you enter on the left track with a straight route, you come to a point where no diverging exit route is possible. While the new signals are not yet working, the old block signal of the Hp light system at the right track is active.
