In mid-June Tunnel Boring Machine Ellie broke through into a cavern 40 m beneath Stepney Green, in the East End of London. The breakthrough marked the structural completion of tunnels for Crossrail’s north east spur, between Whitechapel and Pudding Mill Lane. According to Andrew Wolstenholme, Crossrail Chief Executive, over 80 per cent of the new rail tunnels for Europe’s largest infrastructure project had been completed with the breakthrough at Stepney Green. Roughly one month later another two percentage points were added to this quota, when Crossrail announced at the end of July that the last of 250 000 concrete segments, used to line the tunnels of Europe’s largest infrastructure project had been manufactured.

Since the mid-19th century the River Emscher in the German Ruhr District has been used for disposing of wastewater. In the early 1990s, it was decided to replace the existing open wastewater system with a sewer system and to restore the River Emscher to its natural state. The major Emscher conversion project is divided up into a large number of individual schemes, with construction phase 30 being the biggest. By applying the pipe jacking method interlinking conduit sections with section lengths in excess of 1100 m are produced.

Once again highly topical subjects relating to mobility and tunnelling will be dealt with by the International Tunnel Forum at the InnoTrans in Berlin this year. The STUVA – the Research Association for Underground Transportation Facilities Inc. – is once again responsible for the organization and content of this Forum. Different aspects and in all likelihood different views will be presented and discussed during the two days of the Forum. Every participant will consequently receive stimulation and recommendations for his own activities.
