Special trolleyswitch for small Bustunnel. There are not to much space for 4 stripes in the tunnel, so the outsidewires of each direction are seperate and the insidestripes are used for booth directions at tunnel. Between 16.-20.november 2017 the wires and switches at this street and tunnel was removed. Some scenes you can see in my video after minute 20:15 : https://www.youtube.com/watch?v=dfmyB9X0dj8
