Karlsruhe - Basel HSR

Objective

To untangle severe capacity constraints along one of Europe’s busiest rail corridors, allowing international freight and high-speed passenger trains to pass through southwestern Germany without delaying local commuter networks.

Description

A major four-track expansion along 182 kilometers of the highly traveled Rhine Valley railway, constructing new high-speed passenger bypass tracks alongside dedicated freight corridors. Designated in the Rhine-Alpine Work Plan as a mandatory quadruple-track upgrade to eliminate severe cross-border freight congestion between Germany and Switzerland. Major bottleneck relief project on the German-Swiss border corridor; DB Netz / CEF targets.

History

Formalised by a state treaty between Germany and Switzerland in 1996, the quadrupling of this Rhine Valley line faced massive delays in Germany. Pre-construction turned into a 20-year dispute over noise mitigation and track routing, forcing Deutsche Bahn to accept expensive local demands for underground bored tunnels (such as the Offenburg tunnel) before final planning permissions were secured.
