Deutsche Bahn (DB) has awarded the first construction contracts for its comprehensive overhaul of Germany’s busiest direct city rail connection between Hamburg and Berlin.
The nine-month project, set to begin on 1 August 2025, aims to modernise infrastructure and enhance the passenger experience on the 278-kilometre route, which serves approximately 30,000 travellers each day.
The first contracts have been awarded to SPITZKE SE, Leonhard Weiss GmbH und Co. KG, STRABAG SE and the group subsidiary DB Bahnbau Gruppe.
Project Highlights
- Track and Switch Upgrades: More than 180 kilometres of track and approximately 200 switches will be replaced.
- New Transfer Points: Six additional transfer points will be added to allow faster passenger trains to overtake slower freight trains, increasing operational stability.
- Digitalisation with ETCS: Sections near Hamburg and Berlin will be equipped with the European Train Control System (ETCS) for improved capacity and operational efficiency. Additional ETCS upgrades between Büchen and Nauen are planned for 2030/31 to avoid interim costs of analogue-digital double signalling.
- 28 Stations Renovated: Upgrades will include new weather shelters, improved accessibility, modern toilet facilities, and enhanced wayfinding systems across five federal states.
- Enhanced Mobile Connectivity: The route will feature gigabit-capable mobile communication infrastructure, supported by newly built masts for the Future Rail Mobile Communication System (FRMCS).
To facilitate passenger and freight movements during construction, DB will implement diversion routes and bus replacement services.
This project contributes to DB’s Strong Rail strategy and aligns with Germany’s climate and transport policies by improving rail infrastructure and encouraging a modal shift from road to rail.
Upon completion, the corridor will offer five years free of major construction, efficient infrastructure, and modernised stations for passengers and freight operators.
