A sign warning of a tram catenary of the Kölner Verkehrsbetriebe (KVB) seen on 4 September 2002. First one wonders how high their pantographs must be, but if you look hard, you see that the catenary is 4.0 meters high, not 40 meters. The sign is located on the Ehrenfeldgürtel, but the arrow points into the Hüttenstraße. So I think it does not relate to the catenary of the line 13, but to the one of the line 5 running on the Subbelrather street.
