Together for Hamburg–Berlin.
General overhaul of the metropolitan connection
General overhaul Hamburg–Berlin: With a length of 278 kilometres, this railway line is one of the most important axes in German and European rail transport. More than 470 trains a day make this route the most frequently used direct connection between two cities in Germany. Intensive use, combined with maximum speeds of up to 230 km/h, causes considerable wear and tear on the infrastructure. Regular and comprehensive maintenance measures are therefore essential to ensure reliable and safe rail operations in the long term. The heavily used Hamburg–Berlin line will now undergo comprehensive renovation from August 2025 to April 2026, following the example of the first general overhaul on the Riedbahn line.
The general overhaul will be carried out in three phases:
- Lot 1: Hamburg–Büchen
- Lot 2: Büchen–Dergenthin
- Lot 3: Dergenthin–Berlin
Following a Europe-wide tendering process, we were awarded the contract for the work in Lot 2 last year together with LEONHARD WEISS – and in July 2025, we were also awarded three project contracts in Lot 1. We will keep you regularly updated on the current progress of the construction work here and hope you enjoy browsing our project page.

Project Updates
Update from the Large Scale Projects/Structural Engineering Division
Our teams give their all every day along a stretch of almost 150 km! Between Hamburg-Rothenburgsort and Dergenthin near Perleberg, work is underway everywhere to renew the Hamburg–Berlin railway line. Rails, sleepers and points are being replaced, and electronic signal boxes, overhead lines, signals, crossings and cable duct systems are being rebuilt.
High traffic on the Hamburg–Berlin route
In Dergenthin, Heinrich der Starke, our Track-renewal train UM-S 2001, began replacing rails and sleepers in Lot 2 (Dergenthin–Büchen) this week. The old sleepers are being recycled at our production plant in Möllenhagen and the material wagons are being loaded with new sleepers.
Work has started successfully
Following the official launch of the general overhaul Hamburg–Berlin last Friday, work is now getting underway in earnest. Under the watchful eyes of media representatives, our RM 900 S ballast cleaning machine is continuing with the track reconstruction in Lot 2 near Dergenthin today.
The starting signal has been given
Today marks the start of the nine-month general overhaul of the important Hamburg–Berlin railway line. The official start of the nine-month renovation work was given this morning at the kick-off event in Ludwigslust, which was attended by Philipp Nagl, CEO of DB InfraGO, and representatives of the five federal states involved in the project, among others.
In the starting blocks for Hamburg–Berlin Lot 1
Deutsche Bahn recently awarded the contract for the last remaining construction phase between Hamburg-Rothenburgsort and Büchen (Lot 1) – and we will also play a key role here. In addition to Lot 2 (within a consortium), we are implementing three project contracts in Lot 1. Between 1 August and 30 April 2026, a total of approximately 180 km of track and over 200 sets of points will be renewed on the Hamburg–Berlin line, and work will be carried out at 28 stations.

Hamburg–Berlin Corridor Project Lot 2: We have been commissioned
The general overhaul of the next scheduled corridor project has been finalised. Work will begin between Hamburg and Berlin in August 2025, and we will be involved once again. The contracts for the next corridor project have been signed and we have been commissioned. Following a Europe-wide tendering process, we and LEONHARD WEISS have been awarded the contract to implement the nine-month major project ‘High-Performance Corridor Hamburg-Berlin Lot 2’. Read more
