On 22 April 2006, the parts of the tunneling machine "Tosca", which will drill
the eastern tube of the new underground line, were lifted into the starting pit
at the station Bonner Wall. This is the cutting wheel, still loaded on the
low-loading truck which brought it from the port at Godorf. In the background
the two cranes at the pit are visible.
