New signal box in Munich: S-Bahn is now running on time and smoothly!

Berg am Laim, Deutschland - A new milestone for the Munich S-Bahn is set! At the Munich Ostbahnhof, the old signal box was replaced and a modern electronic signal box (ESTW) was put into operation. Together with a second signal box at the Leuchtenbergring, this will revolutionize traffic control in the Bavarian capital. The changeover took place between June 6th and 18th, 2023 and went, as reported, such as Augsburger Allgemeine. Only slight adjustments had to be made afterwards.

The new signal box replaces a relay park that has been in use since 1971 and was one of the most frequented people in Germany. With over 150 signals and 60 soft, the ESTW Munich Ost now controls the signals and gives way to the first S-Bahn line, which is known to be the densely used railway line in Europe. The Leuchtenbergring signal box is also used and is currently heading for the section between Leuchtenbergring and Berg am Laim; The second S-Bahn line will take over in the future.

investments in the future

Deutsche Bahn has invested significant resources in the two signal boxes. So far, the federal government has pumped 195 million euros into these new technologies, and that is also necessary! Every day, around 840,000 passengers benefit from the new high-tech brain, which should not only increase the punctuality and reliability of S-Bahn traffic, but is also a prerequisite for the construction of the second S-Bahn master route. This was confirmed by Deutsche Bahn.

The modernization is part of the DB program "S3", which is supposed to make the train more punctual and reliable. And this is not only worth it for the commuters: The rail infrastructure is also prepared for future challenges by these measures. Finally, the stable journeys have shown that the measures have fruits.

new trains in view

The future of the Munich S-Bahn does not only look promising at the infrastructure level. Siemens Mobility has announced the delivery of 90 new S-Bahn trains with an order value of over two billion euros. These trains, which should go to passenger operation from the end of 2028, will offer more space, better comfort and numerous technical innovations. These new acquisitions are another step to modernize S-Bahn traffic in Munich and to meet the demands of passengers, as Siemens.

Overall, it can be said: Munich is well on the way to not only optimizing the existing infrastructure in S-Bahn traffic, but also investing in the future. So there is a lot of reason for joy and commuter traffic could soon become even more pleasant and efficient!
