Since late 2010 a new stretch of the U6 urban railway in Stuttgart has connected the districts of Möhringen and Fasanenhof and integrates the Fasanenhof Ost commercial and residential district in the urban railway network. This newly built stretch is 2,750 metres long, more than 1,000 metres of which runs in tunnels.
The twin-tracked tunnels were constructed using cut-and-cover techniques for 650 metres and tunnelled for another 370 metres. The tunnel, driven using a shovel loader and shotcrete lining, passes below a block of flats, a commercial operation and a federal road, creating four new stops. When the U6 came into service on 11 December 2010, the Stuttgart urban railway network grew to around 125 kilometres.
Both straight and curved JORDAHL® anchor channels were used to safely and economically install the catenaries and stays in both tunnels, thereby guaranteeing secure catenary fixing even after millions of load cycles.
