Major Delays Plague Hamburg-Berlin Rail Line Post-Renovation
Hamburg, Germany, September 5, 2026 – The rail line connecting Hamburg and Berlin, which underwent a comprehensive ten-month renovation, continues to be plagued by massive delays and cancellations, according to figures released in response to a parliamentary inquiry by the Green Party.
Since its reopening on June 14, 2026, the route has experienced anything but smooth operations. Between June 14 and July 26, a total of 3,150 long-distance train journeys were recorded. Approximately 74% of these journeys were delayed by at least six minutes, and 219 trains suffered delays of more than 90 minutes. Additionally, 172 scheduled long-distance trains operated by Deutsche Bahn (DB) were cancelled during this period.
Initial Weeks Marked by Significant Disruptions
The situation was particularly dire immediately following the reopening. From June 14 to June 30, only 239 out of 1,272 recorded long-distance trains departed the route with a delay of less than six minutes. On June 27 alone, 28 out of 51 planned DB long-distance trains were cancelled. While the situation improved in July, it remained significantly below the desired service level.
The federal government acknowledges that punctuality targets have not been met post-renovation. Cited causes include extreme heat days, such as June 27, which led to high rail temperatures, local storms, and the ripple effects of other construction work at the Berlin railway hub. Frequent specific causes of delays also included already delayed preceding trains, issues with the control and safety technology, and irregularities during construction work. Furthermore, some parts of the new technology were not fully operational immediately after the reopening.
Deutsche Bahn Reports Improvements, Ongoing Work
Deutsche Bahn, in a statement to rbb, reported a recent positive trend, admitting that operational quality in the initial weeks was “unsatisfactory for various reasons.” They noted numerous incidents in the Altmark region, in addition to local storms. However, DB now observes increasing punctuality and fewer disruptions compared to the period before the renovation.
The work on the line is not yet entirely complete. Restorations are currently underway, and the requirements for a high-speed line are particularly stringent. Some errors and optimization needs only become apparent “after several weeks of regular load.”
Most of the line has been capable of speeds up to 230 kilometers per hour since June. Further sections near Nauen were also cleared for high-speed operation early this week. However, additional nocturnal closures of partial sections will be necessary in the coming weeks for further commissioning.
DB had previously announced that acceptance tests and rework would be necessary after the official reopening. In mid-June, they stated that acceptance drives and speed restrictions would initially be required on certain sections.
Pro Bahn Criticizes Explanations and Demands Action
The passenger association Pro Bahn considers the explanations for the difficulties insufficient. They argue that heat and storms are not unique to the Hamburg-Berlin connection and have affected other rail lines. The association points to structural problems in the modernization of the railway, including a lack of planning and testing capacities for the new control and safety technology.
Pro Bahn also criticized Deutsche Bahn’s “hasty and chaotic” planning for the re-commissioning. From their perspective, the line should have remained closed for an additional week or two to rectify deficiencies before reopening. Therefore, Pro Bahn is calling for a joint summit involving the federal government, DB, and the rail industry to develop a strategy for ensuring sufficient personnel for planning, construction, and technical approvals.
The federal government itself has acknowledged difficulties in the acceptance of control and safety technology. Extensive technical verification processes make the time required for assessments and approvals difficult to predict. For future corridor renovations, individual tasks and approvals are to be shifted more to before or after the main construction phase.
Green Party Criticizes Passenger Information
Green Party Bundestag members Linda Heitmann and Katharina Beck, who were involved in the parliamentary inquiry, highlighted the plight of commuters. After the long closure, “even low expectations regarding functionality were unfortunately still undercut.” They also criticized passenger information during disruptions, demanding that travelers be informed earlier about the reasons for delays, their expected duration, and alternative travel options.
The problems on the Hamburg-Berlin route could also impact future general renovations. The Federal Ministry of Transport is currently reviewing its strategy for so-called corridor renovations. According to the federal government, this review will specifically investigate why promised deadlines for re-commissioning were not met and why the incidence of disruptions did not decrease as expected afterward.
