Germany's rail chaos deepens as Deutsche Bahn overhauls key high-speed routes

Deutsche Bahn (DB) is pressing ahead with major upgrades to some of Germany’s busiest rail routes. Work on the Berlin-Hamburg line, which began last year, is now due to finish this summer after earlier setbacks. Meanwhile, further disruptions loom as another key route undergoes extensive renovation later in the year.

The Hamburg-Berlin route has been under construction since August last year, forcing passengers onto replacement buses and diverted trains. Originally set to reopen in late April, the line will now resume service in mid-June after additional delays.

From October 2, attention shifts to the Hannover-Berlin line, where a large-scale modernisation project will run until December 12. Track upgrades, overhead line repairs, and signalling improvements will take place, though further postponements remain possible. During this period, ICE trains between Hannover and Berlin will face delays of up to 80 minutes, with services cut to just one per hour. The overhaul will also disrupt other connections. The ICE route via Kassel, linking Braunschweig to Frankfurt, will close entirely. Wolfsburg will lose all long-distance rail services, while Helmstedt will see a sharp reduction in connections. Travellers on the Amsterdam-Berlin route will have only one train every four hours, with journey times extended by as much as 70 minutes.

The upgrades form part of DB’s wider push to modernise Germany’s most vital high-speed rail links. Once complete, the improvements aim to boost reliability and punctuality on some of the country’s busiest routes. Passengers, however, must contend with months of reduced services and longer travel times in the meantime.
