German parliamentary committee approves new Hamburg-Hannover rail line alongside 250 million euro track upgrade

Committee decision and compromise

The Bundestag transport committee voted on Wednesday morning to advance planning for a new rail line between Hamburg and Hannover, while concurrently ordering upgrades to the existing corridor. The draft resolution permits Deutsche Bahn to continue development of its preferred route through its infrastructure division, DB InfraGO. Lawmakers paired the new track construction with roughly 250 million euros in dedicated funding to modernise the current railway line via Lüneburg, Uelzen, and Celle by 2034 at the latest. The decision followed two weeks of delay after coalition partners previously postponed the vote over regional concerns. Isabel Cademartori, transport policy spokesperson for the Social Democratic Party (SPD) parliamentary group, described the resolution as a balanced solution to persistent bottlenecks.

We are ending years of standstill on Hamburg-Hannover and finally bringing new construction and improvements to the existing line together.

Overcapacity and network constraints

The existing rail link connecting Hamburg and Hannover is among the most congested corridors in the German rail network. According to data from Deutsche Bahn, track capacity utilisation along the route reaches up to 147 percent, causing routine delays for long-distance, regional, and freight operations. A report submitted by the Federal Ministry of Transport to the committee identified the corridor as a critical bottleneck for freight transit between northern German ports and southern industrial centres. Christoph Ploß, a Christian Democratic Union (CDU) member of parliament, stressed that new track capacity is necessary to address structural traffic shortages. Additional funds for the existing line will target enhanced noise protection, operational modifications, and potential new regional stations.

The new line is a central component to create additional capacity and permanently resolve existing bottlenecks between Hamburg and Hannover.

Political reactions and regional concerns

The proposal for a new line through Lower Saxony has faced local political resistance for decades, leading to internal divisions within the federal black-red coalition. CDU parliamentarians from Lower Saxony had raised objections during earlier committee sessions, while SPD co-leader and Vice Chancellor Lars Klingbeil has long argued against new construction cutting through his constituency in the Lüneburger Heide. In contrast, officials in Hamburg welcomed the committee vote as a step toward relieving commuter strain across the southern metropolitan area. Hamburg Transport Senator Anjes Tjarks welcomed the vote as a step toward addressing capacity issues in northern Germany, while demanding rapid progress on planning.

Therefore, clarity is also needed quickly regarding financing.

Tjarks also noted that Germany should maintain the ambition to complete construction well before 2050.

Implementation timeline and corridor refurbishment

The full Bundestag is scheduled to debate and vote on the draft resolution late on Thursday evening, where approval by coalition lawmakers is considered a formality. In addition to planning the new line, transport authorities are preparing a comprehensive corridor refurbishment of the existing tracks, initially slated for 2029. Under that overhaul concept, high-traffic corridors are closed completely for several months of concentrated maintenance. Federal Transport Minister Steffen Bilger is currently reviewing the broader nationwide schedule for corridor renovations following technical disruptions on recently reopened lines, which may reduce the number of track overhauls conducted each year. Further planning will proceed based on the preferred variant submitted by DB InfraGO as federal officials seek final legislative endorsement.
