A pure main signal of the Ks system which is still marked as invalid (by the white cross), seen at the new overtaking station Dorsfeld (on Cologne-Aachen) on 15 July 2001. It serves as exit signal of the northern siding and has a Zs3 (speed limit, probably 100 km/h due to switches), but no Sh1 (shunting signal), so if shunting is needed it will be done with explicit orders.
