Deutsche Bahn plans new Wallauer Spange rail link near Wiesbaden

The roughly four-kilometre, double-track Wallauer Spange is designed to create a direct rail link between the Cologne–Rhine/Main high-speed line and the Frankfurt branch, cutting travel time between Wiesbaden main station and Frankfurt Airport's long-distance station from 33 to 16 minutes; a new barrier-free stop with two side platforms on state road L3017 is part of the project. Revised planning-approval documents were resubmitted in April 2026, with a public hearing scheduled for Q1 2027. Planned completion/opening per the project list: end of 2029.
