The Katzenberg Tunnel between Efringen-Kirchen and Bad Bellingen is almost 10 km long and is a twin-tube rail tunnel operated by DB Netz AG. It is part of the Karlsruhe-Basel expansion and new construction line (northern access route to the NEAT) and was put into operation at the timetable change in December 2012. The two single-track tubes are equipped with a fixed track for maintenance and rescue vehicles and can be used by trains traveling at speeds of up to 250 kilometers per hour. The Katzenberg Tunnel will serve to increase capacity and speed on the Rhine Valley Railway and to relieve the communities along the old line of freight and high-speed traffic.
