The crossing of Aachener Straße and Gürtel in Cologne seen from the 18th floor of the DKV building on 26 June 2004. This is the only crossing where running from each direction into each direction is possible. Line 1 and line 13 run straight through, the 1 from the lower right corner (towards Weiden) to the upper left (towards the city center and Bensberg), the 13 from the right side (towards Sülzgürtel) to the left (towards the northern Gürtel and Holweide). Line 7 uses the connection from the right (towards Frechen, leaving the Gürtel again further south) to the upper left (towards the city center and Zündorf). The two connections to the left are frequently used by trains to and from the West depot, which is reached by a short line branching from the Gürtel about hundred meters north of this crossing. Two low-floor trams of 4000 series are just heading for the depot. There are four platforms, each one located in front of the crossing where the trams have to wait anyway in most cases.
