Germany’s rail infrastructure company DB Netz has indicated that work is set to start on repairing the tunnel bore that collapsed at Rastatt in August.
The eastern bore of the twin tunnels failed causing subsidence to a rail line above and was later backfilled with concrete to allow the surface rail route to be repaired and reopen earlier this month.
DB Netz has issued a number of contract variation notices to its joint venture contractors Hochtief and Züblin in the Official Journal of the European Union suggesting that work to progress the tunnel scheme is underway.
The notices cover issues relating to bentonite contamination issues, managing groundwater flows at the site and further drainage work around the platform structures which were built to support the surface rail route.
DB Netz has not yet made any comment on the investigation into the cause of the collapse.
