Deutsche Bahn expands Rhine Valley Railway sections near Basel

The roughly 5 km PFA 9.2 section between Haltingen and Weil am Rhein is being expanded to six tracks (two each for long-distance, freight and regional traffic) with modernized stations at Haltingen and Weil am Rhein; construction began in 2011 and, per Wikipedia, completion is planned for end of 2028. The roughly 3.1 km PFA 9.3 section in Basel, entirely on Swiss territory (border to Badischer Bahnhof), has been under construction since June 2021 and is due to be completed mid-2028. A combined planning/construction budget of about EUR 400 million was agreed for both sections in 2010; the overall Karlsruhe–Basel project is estimated at roughly EUR 14.2 billion (as of May 2020).
