The Karlsruhe-Basel line extension is of strategic significance to cross-regional, European and international rail traffic. Because of its geographical position, it is part of Europe’s most important freight traffic corridor, Rotterdam-Cologne-Basel-Milan-Genoa.
At over 150 years old, the line between Karlsruhe and Basel, also known as the Rhine Valley line, is one of the oldest and most frequently travelled railway lines in southwest Germany. Over 250 local, long distance and freight trains travel daily along the 182 km double-track line between Karlsruhe and Basel. It has therefore reached its capacity limit. Adapting the lines to meet the demands of current and future traffic is urgently required in light of existing bottlenecks and the resulting quality constraints, as well as the increased traffic expected in years to come.
The Karlsruhe-Basel line extension and new constructions have been conceived with a four-track extension in mind, in order to significantly increase line capacity and reduce travel and transport times.
