Hamburg-Berlin rail line reopens after corridor overhaul

Deutsche Bahn has reopened the Hamburg-Berlin rail corridor after a six-week delay to its planned return to service, restoring full traffic on one of Germany’s most important intercity routes.

The first long-distance train left Hamburg Hauptbahnhof for Berlin early on June 14, while freight trains had already begun using the freshly renovated line the previous evening, according to reporting from WELT. DB had originally aimed to finish the work by the end of April, but winter weather and frozen ground pushed the restart back.

A long closure, then a delayed reopening

The corridor had been closed since August 1, 2025 for a major overhaul. During the shutdown, long-distance trains and freight traffic were diverted via Stendal and Uelzen, and passengers used replacement bus services on disrupted sections.

Regional service between Hamburg and Schwerin and Hagenow Land resumed earlier, on May 15, giving commuters a partial return before the full line reopened.

The reopening matters because the Hamburg-Berlin route is one of Germany’s busiest rail links and a key connection between the country’s two largest cities. Its return also restores freight capacity on a corridor that had been unavailable for months.

What DB changed

The overhaul covered major infrastructure work along the line. Reporting says the project included 165 kilometers of renewed track, 61 kilometers of refurbished track, 249 switches and 28 modernized stations.

A separate pre-opening report said DB expected the line to be back in regular operation on June 14, though long-distance trains could still run a few minutes late during final test and acceptance runs tied to new signaling and interlocking technology between Hagenow Land and Berlin-Spandau.

WELT said DB was warning passengers to check departures before traveling because some initial teething problems were possible after the restart. That leaves the first days of service under close watch for punctuality and any residual restrictions.

What to watch next

The immediate questions are operational: whether long-distance services stabilize, whether any temporary speed limits or other adjustments remain in place, and whether the corridor avoids further knock-on delays after the restart.

The reopening also places DB’s wider corridor-renewal program back under public scrutiny. The Hamburg-Berlin line is a high-profile test case because it carries heavy passenger traffic, supports freight movement and affects commuters and towns along the route, including Wittenberge.
