Cars are to pass through the Fehmarn Belt tunnel first. Trains will follow later.
That is the assumption Sund & Bælt is working with while uncertainty remains over when the German infrastructure will be ready.
A new German plan puts the opening of the Fehmarn Sound tunnel between Fehmarn and the German mainland at no later than 2035. According to the authorities in Schleswig-Holstein, the previous expectation was 2031/2032. Sund & Bælt is, however, not aware of any decision having been made on a new timetable for the German part of the project.
- On the Danish side, we are now working on the assumption of a two-stage opening, with road traffic first and rail later, Sund & Bælt writes in a response to FemernBusiness.
The group points out that Deutsche Bahn already warned in August 2025 that the German rail infrastructure would be delayed. From a financial perspective, road traffic matters most.
- Viewed in isolation, a later opening of the railway is expected to have only limited financial consequences, as by far the majority of revenues come from road traffic, Sund & Bælt writes.
How rail traffic will be handled during an interim period, and what this means for the overall timetable, remain part of ongoing discussions between the Danish and German authorities.
