Stable alternative transportation between Hamburg and Berlin as railway undergoes renovation
Renovation of Hamburg-Berlin Railway Line Underway
Germany's major rail corridors, including the "40 corridor," are undergoing extensive renovation as part of Deutsche Bahn’s (DB) extended general refurbishment program. This program, scheduled to complete by 2036, focuses on upgrading tracks, signalling, stations, and other infrastructure to modernize the overloaded and dilapidated track network.
The Hamburg–Berlin railway line is one of the key routes affected by this renovation. From August 1, 2025, to April 30, 2026, the line will undergo a full closure and intensive renovation, lasting nine months. The line, spanning 278 kilometres, carries around 230 trains daily and approximately 30,000 passengers.
The renovation involves three construction sections: Hamburg–Büchen, Büchen–Dergenthin, and Dergenthin–Berlin. Over 180 km of track and 200 switches will be renewed, six new transfer points built for better traffic management, along with upgrades to signal boxes and control systems. A total of 28 stations will be modernized. Surrounding sections will also be affected due to signal and control system upgrades.
During the closure, long-distance trains will be rerouted with detours of around 100 km or more, and regional connections will be replaced by 170 buses daily to maintain service for intermediate towns. The replacement buses are longer than the regional trains that would otherwise run on the route. Passengers in regional traffic are reliant on buses during the renovation. Real-time travel information will be provided through digital platforms.
However, the renovation is not affecting long-distance traffic. ICE and IC trains are still being rerouted via Stendal and Uelzen since Friday evening. These trains are running less frequently and taking around 45 minutes longer than usual due to the renovation. Replacement buses run to and from Wittenberge, with services usually every half or full hour.
The construction trains are transporting rails, sleepers, and ballast from approximately 130 construction sites along the line. The work has begun, involving the dismantling of cables and switch drives, and the removal of magnets for controlling signals.
The renovation of the Hamburg-Berlin line is part of more than 40 corridor renovations aimed at updating the overloaded and dilapidated track network by 2036. Beyond Hamburg–Berlin, the ongoing "Generalsanierung" covers approximately 4,000 km of heavily used railway lines across Germany. The renovation timeline from 2026 to 2027 includes corridors like Hagen–Wuppertal–Cologne, Nuremberg–Regensburg, Rosenheim–Salzburg, and Lehrte–Berlin. Post-2027, work will continue on routes such as Cologne–Mainz, Munich–Rosenheim, and Lübeck–Hamburg. Some project timelines, like Lübeck–Hamburg and Frankfurt–Heidelberg, are deferred to later years.
Despite the disruption caused by the renovation, the railway company reports that the replacement traffic is running smoothly. The journey from Wittenberge to Berlin's main station will take three and a half hours during the renovation, compared to the usual one and a half hours. Employees of the railway company and Ecovista will be adjusting routes in the coming days.
