Deutsche Bahn Splits Munich–Rosenheim Rail Overhaul into Two Phases, Avoiding Six-Month Shutdown
Deutsche Bahn has abandoned plans for a six-month total closure of the key Munich–Rosenheim corridor, instead scheduling two shorter construction phases in 2028 and 2031 to reduce disruption for commuters and international freight.
A revised strategy for a critical corridor
The heavily used rail line between Munich and Rosenheim, one of Bavaria's most important railway connections, will be modernized in two separate phases rather than under a single prolonged shutdown. DB InfraGO, the infrastructure arm of Deutsche Bahn, announced the adjusted plan on Friday, stating the goal is to minimize simultaneous disruption to S-Bahn and long-distance services as well as restrictions on international rail freight.
The route carries regional, long-distance, and freight trains daily, along with S-Bahn services between Munich and Grafing. It is also a vital link for future traffic through the Brenner Base Tunnel. The infrastructure upgrade is now timed to deliver a more reliable and higher-capacity line before that tunnel is completed.
Preparatory work starting in autumn 2027
Before the main construction kicks off, preparatory measures will begin in autumn 2027. During this early stage, the S-Bahn line will be closed in sections. Additional restrictions and weekend closures are planned for early 2028, including during the Carnival holidays.
- Preparatory measures begin; S-Bahn line closed in sections.
- Weekend and Carnival holiday closures planned.
- Phase 1 starts: eight-week full closure of long-distance tracks for signal box replacement and track work.
- Phase 1 ends.
- Phase 2 begins: renewal of tracks, switches, overhead lines, bridges, stations, and ETCS installation.
- Phase 2 scheduled to conclude.
Phase one: eight-week closure in early 2028
The first major construction phase is scheduled to run from mid-February to mid-April 2028. For these eight weeks, the long-distance tracks will be completely closed. The primary focus will be replacing old signal boxes and carrying out work on tracks and switches. Long-distance trains will be diverted, and replacement buses will serve regional passengers.
Phase two: a broader overhaul in 2031
The second phase is slated for the first half of 2031. This stage will involve renewing tracks, switches, overhead lines, bridges, and stations. The line will also be equipped with the European Train Control System (ETCS). Details on the specific closures and diversions required for this later phase have not yet been released.
Strategic timing around the Brenner Base Tunnel
Deutsche Bahn emphasized that the revised schedule ensures the Munich–Rosenheim infrastructure will be upgraded and made more resilient in time for the opening of the Brenner Base Tunnel. By splitting the work, the operator aims to keep this essential north-south artery functioning for both passenger and freight traffic throughout the construction period.
