Passengers across Cologne, Wuppertal and Hagen can expect months of travel disruptions as one of North Rhine-Westphalia’s busiest railways is set for serious renovations.
Starting February 6th, Deutsche Bahn (DB) is set to fully close a length of tracks between Cologne, Wuppertal and Hagen for a five‑month general renovation, scheduled to run until July 10th.
Meanwhile, passengers in Cologne can expect the start of timetable changes for local railway services from January 30th, ahead of the main closure.
The project aims to modernise a key transport artery in North Rhine-Westphalia (NRW). In the meantime, however, travellers should be prepared for major changes to their usual journeys, including months of closures, diversions and replacement buses.
How will rail passengers be affected?
Passengers using this route can expect to see changes across almost all regional and long‑distance services.
During the full closure, several regional express and S‑Bahn lines will either be diverted or replaced by bus services. These include the RE4, RE7, RE13, RE49, RB48 and S‑Bahn lines S7, S8, S9, S28 and S68.
In many cases, trains won’t run at all along the affected stretch, with DB providing a mix of express buses and others with interim stops.
Long‑distance services will also be heavily disrupted. Trains that normally run between Cologne and Dortmund will be diverted via Düsseldorf and Essen, adding travel time and omitting the usual stops through Wuppertal.

According to the plans, ICE services between Cologne and Berlin will continue to operate hourly, but will take the longer diversion via Düsseldorf, Duisburg, Essen and Bochum – extending typical journeys by about 20 to 30 minutes.
International and cross‑regional services are set to be affected as well. IC trains connecting Stuttgart, Mainz, Cologne, Hanover, Magdeburg and Dresden will operate only between Stuttgart and Cologne and between Dortmund and Dresden during the works.
Before the main closure begins, passengers in Cologne can expect changes to their normal timetable from January 30th, expected to include cancellations or diversions on S‑Bahn lines near Cologne‑Messe/Deutz and Cologne ‑ Trimbornstraße.
DB is advising passengers to plan their journeys carefully, allow extra time and check updated timetables before travelling.
More detailed route‑by‑route information is available on the Deutsche Bahn website or in the Baustellenmeldungen section of the DB Navigator app.

How long are the works expected to last?
The main closure starts on February 6th and is due to end on July 10th, amounting to just over five months. During roughly one‑third of this period, the line will be completely shut to all train traffic.
The remaining weeks will involve phased closures, diversions, and restricted operations as various parts of the project progress.
Why are the works taking place?
DB says the upcoming overhaul aims to make the line “more reliable and efficient in the long term”.
The Cologne–Wuppertal–Hagen corridor is one of the most heavily used railway sections in the region, carrying a mix of long‑distance, regional and freight trains. After years of intensive use, it’s become prone to delays due to wear.
The scale of the project is extensive. Crews will replace around 80 kilometres of track, renew 28 switches, and modernise nearly 30 kilometres of overhead line equipment.

They will also construct roughly four kilometres of new noise protection barriers, making the line quieter for local residents, and begin modernising twelve stations to improve accessibility and platform quality.
Although passengers will feel the inconvenience now, DB suggests that the benefits will be felt for years to come.
