New digital era: S-Bahn traffic in Munich restricted during Pentecost!
A major project is in the starting blocks at Deutsche Bahn: a new electronic signal box (ESTW) will be put into operation at Munich's Ostbahnhof next Friday, June 7th. The commissioning will have a major impact on S-Bahn traffic, and passengers will have to prepare for restrictions during the Whitsun holidays. These extend until June 13th at 4am, like tz.de reported.
The changeover to the new signal box is no easy task: around 8,000 acceptance hours were necessary to put the system into operation. The work includes a software change and the coordination of the control and safety technology, which ensures that the switches and signals in the S-Bahn network work smoothly. The old system, which was based on relay technology from the 1970s, is being replaced by modern technology designed for stability and efficiency. The 2nd main route also benefits from these innovations, like that Bavarian Radio highlights.
Timetable changes: what does this mean for travelers?
The restrictions begin in three phases: First, there will be a software change from Friday evening to Saturday morning, which means that the main route and areas around Ostbahnhof will be temporarily closed. The S-Bahn lines must end early and replacement buses will be provided every 10 minutes between Pasing and Ostbahnhof.
- S 1: Freising/Flughafen – Leuchtenbergring; Züge halten nicht an der Hackerbrücke und enden am Hauptbahnhof.
- S 2: Petershausen/Altomünster – Erding; Züge beginnen/enden am Isartor und am Ostbahnhof, fahren von/bis Riem ohne Halt.
- S 3: Mammendorf – Holzkirchen; Züge enden am Isartor bzw. in Giesing.
- S 8: Herrsching – Flughafen; Züge beginnen/enden in Johanneskirchen, auch hier gibt es einen Ersatzverkehr.
- S 20: Verkehrt gar nicht zwischen Pasing und Höllriegelskreuth.
In phase two, which lasts until Friday, June 13th, the S-Bahn tracks in the area of the new signal box will not be accessible. The replacement service will then be offered between Isartor and Ostbahnhof every 5 minutes, while the timetables of the S-Bahn lines continue to be adjusted. From Monday, June 15th, the tracks will be accessible again, but S-Bahn traffic will be reduced by around a quarter, as Deutsche Bahn explains in detail ( deutschebahn.com ).
Information measures for passengers
Deutsche Bahn has taken comprehensive information measures to make the transition easier for travelers. Information steles at train stations, QR codes for quick orientation and first-hand information from employees on site ensure clarity during this transition phase. There are also announcements and banners that draw attention to current developments.
Overall, the commissioning of the new signal box offers great opportunities for stabilizing and improving S-Bahn operations in the Munich area. The hope is that the new system will improve reliability and punctuality in S-Bahn traffic - a hope that the Pro Bahn passenger association shares, even if they point out the challenges on the external routes.
