The catenary configuration at the corner Gräfrather
Straße/Rubensstraße seen on 13 September 2003. Busses of line 683
coming down the Gräfrather Straße turn left into the
Rubensstraße here. Then they run via Vohwinkeler Straße and come up
the Gräfrather Straße again. So the catenary crosses itself here.
