Deutsche Bahn rail corridor renovations are now underway, with DB InfraGO beginning two major infrastructure works programmes in North Rhine-Westphalia and Bavaria on the Hagen–Wuppertal–Cologne and Nuremberg–Regensburg lines, as Railway News reports.

In both cases, the plans come with full route closures, diversions for long-distance and freight trains, and large replacement bus services for regional passengers.

DB InfraGO corridor renovation projects in North Rhine-Westphalia

The Hagen–Wuppertal–Cologne works were launched at Wuppertal-Elberfeld by DB InfraGO chief executive Dr Philipp Nagl, together with Federal Transport Ministry state secretary Christian Hirte and North Rhine-Westphalia transport minister Oliver Krischer.

The programme covers renewing or refurbishing 81 kilometres of track, replacing 50 switches and upgrading 29 kilometres of overhead line equipment on the corridor between the Ruhr area, Bergisches Land and Cologne, as set out in a Deutsche Bahn press release. Nearly four kilometres of new noise barriers are also planned.

Stations are a key part of the North Rhine-Westphalia work, too. Twelve stations — including Wuppertal and Solingen main stations as well as several smaller stops — are due to be modernised, with step-free access and upgraded facilities. While the main closure covers the core construction window, station works are expected to continue beyond it and run into 2027.

Closures, diversions and replacement bus services

With the line closed for the main works, long-distance and freight trains will be diverted and some services will be cancelled on sections between Cologne and Dortmund. Journey times on diverted routes are expected to increase by around 20 to 30 minutes. Regional and S-Bahn services are being replaced by up to 200 buses, operating a mix of stopping and express routes.

Nagl said the scheme forms part of DB InfraGO infrastructure works on one of North Rhine-Westphalia’s most important local and long-distance corridors.

In his comments, he pointed to track renewal and switch replacement, overhead line equipment renewal and station upgrades as steps intended to deliver modern and attractive stations in the future, and to make the infrastructure more robust so train traffic can run more smoothly across Germany.

He also acknowledged that the renovation would be a demanding undertaking for construction teams as well as passengers, residents and businesses, but said he expects the effort to be worthwhile.

Nuremberg–Regensburg corridor renovation in Bavaria

In Bavaria, DB InfraGO has also started a full renovation of the Nuremberg–Regensburg corridor. The start event took place in Neumarkt in der Oberpfalz with DB InfraGO board member Gerd-Dietrich Bolte, Federal Transport Ministry state secretary Ulrich Lange and Bavarian transport minister Christian Bernreiter.

The Nuremberg–Regensburg line is around 88 kilometres long and carries more than 350 trains per day. It will be fully closed for construction until 10 July 2026. Works include renewal or major maintenance of 96 kilometres of track, replacement of 74 switches and upgrades across 81 kilometres of overhead line systems. Signalling and safety equipment will be upgraded, preparations made for the European Train Control System, and embankments and a bridge will be repaired. Twenty stations along the route will be modernised, with step-free access a central element.

Bolte described the comprehensive modernisation as an ambitious construction project on one of Bavaria’s most important lines, combining upgrades to tracks, switches, signalling and safety technology, as well as overhead lines, while also addressing the 20 stations on the corridor.

He added that the coming months will be demanding for construction teams and passengers, but said he is confident the work will help ensure more robust infrastructure and smoother train operations across Germany—an approach that aligns with the wider corridor renewal plan previously outlined by Railway Supply.
