On the important connection between Cologne and Aachen, train cancellations and diversions continue due to two damaged switches. Affected are RE1, RE9, RB38 as well as ICE trains between Brussels and Frankfurt am Main.
Quick overview
This report is particularly relevant for rail travelers because it may have concrete effects on planning, connections or infrastructure. The focus is on Deutsche Bahn, NRW, Koelnaachen, Re1, Re9, Rb38, construction site, commuters and long-distance traffic. The key points are summarized compactly below.
Key points
- Two switches on the Cologne–Aachen line were damaged by a construction train, according to Deutsche Bahn, and must be repaired.
- RE1 and RE9 continue to be partially cancelled between Cologne Hauptbahnhof and Düren; the RB38 is restricted between Horrem and Köln Messe/Deutz.
- As an alternative, Deutsche Bahn recommends the S19 between Düren and Köln Messe/Deutz; replacement buses run between Aachen Hbf and Düren as well as between Aachen Hbf and Cologne Hbf.
- ICE trains on the Brussels–Aachen–Cologne–Frankfurt am Main route are being diverted, journey times are extended and the stop at Düren is suspended until further notice.
- The construction work that has been ongoing since the end of June was originally scheduled to be completed on 24 July – completion is now delayed again.
What this means for travelers
For travelers, it is worth taking a close look at the time period, route and booking conditions. The key question is whether the report already triggers concrete timetable changes or initially describes a political or strategic development.
Context
Extensive construction work has been taking place on the Cologne–Aachen route since the end of June 2026. The originally planned completion on 24 July 2026 was pushed back by new switch damage caused by a construction train, extending the restrictions for commuters and long-distance travelers.
What to watch now
- Check concrete timetable or construction notices only once travel dates are set.
- Allow more generous connection times for international journeys.
- Keep an eye on the source and operator information in case dates are still provisional.
