Germany's longest ongoing rail infrastructure project: a full four-track expansion of the Upper Rhine corridor between Karlsruhe and Basel, a key bottleneck on the Rotterdam–Genoa freight corridor. The project includes the 4.3 km Katzenbergtunnel (completed 2012) and the critical Rastatt Tunnel section. Completion of all sections is expected around 2041.
