Commuters beware: Munich-Mühldorf railway line closed until September!
The railway line between Munich and Mühldorf has been closed for several weeks since August 11, 2025 in order to carry out extensive modernization work. This closure, which will last until September 15, 2025 at 7:11 a.m., affects the two regional train lines RB40 and RE4. Travelers should be prepared that trains will be canceled during this time and that replacement bus services will be set up. Loud tz.de The modernization of the signal box technology is the reason for the measure.
The replacement traffic is well organized. There are several bus services that take travelers safely to their destination. Between Mühldorf and Munich Ost/Friedenstraße the buses stop at all stops along the way. In addition, there are direct buses between Mühldorf, Ampfing and Messestadt Ost, with stops in Ampfing only to get off. There are also direct buses between Dorfen and Messestadt Ost. The MVG subway line 2 can be used for the route between Messestadt Ost and Munich East/Munich Central Station. The departure point for the buses in Messestadt Ost is Willy-Brandt-Allee, platform 5.
Technical innovations for more efficiency
The work includes replacing mechanical signal boxes with modern electronic signal boxes (ESTW). This will take place in two construction stages, with the first new systems in Hörlkofen and Thann-Matzbach scheduled to be put into operation at the end of 2025. The signal boxes in Schwindegg and Weidenbach/Heldenstein will follow in a later phase. This conversion is part of a large-scale project to improve the rail infrastructure, which was initiated by a cabinet decision of the federal government on June 25, 2025. These measures are part of investments worth around 107 billion euros intended for the renovation and modernization of existing railway lines, such as Future public transport network reported.
These major investments will pave the way for a new digital rail operating system known as the European Train Control System (ETCS). ETCS ensures greater safety and efficiency in train traffic, especially through shorter train headways, making the entire network more efficient.
Information for travelers
Deutsche Bahn asks all travelers to find out the latest information on platforms such as bahn.de, DB Navigator or the Südostbayernbahn website before their journey. This ensures that passengers are well informed about any changes and alternatives.
Modernizing the rail infrastructure is an important step in increasing the attractiveness of rail transport and ensuring construction-free operations in the future. Federal Transport Minister Patrick Schnieder emphasizes that this is the beginning of ending the renovation backlog in the transport infrastructure and emphasizes that, in addition to the renovation, new rail and road construction projects are also being taken into account.
