The S-Bahn main line in Stuttgart will remain closed for extensive construction work during the summer holidays. FromJuly 26th to September 5th, 2025Commuters and travelers cannot travel between the main station and Vaihingen as usual. This has an impact on various lines, which will have their services severely restricted on the above-mentioned event days.

The S-Bahn line S3 will only reachFellbachrun, while the S2 ends at Stuttgart main station and does not stop at Nürnberger Straße and Sommerrain. The frequency on line S1 will also be reduced from a fast service to just half an hour. Commuters are already used to such restrictions, as there have been similar closures in the past, which are being discussed in the region's transport committee.

Rail replacement services and extensions

Given the lockdown, theStuttgart Region Association (VRS)approximately250,000 eurosinvest in rail replacement transport (SEV). Buses will run between the stops Hauptbahnhof, Stadtmitte, Feuersee, Schwabstraße, Universität, Österfeld and Vaihingen in order to close the gap in the S-Bahn network.

In addition, additional regional express trains are used, which run between the main station and Böblingen via Stuttgart-Vaihingen. The U1 light rail line will also be extended to Stuttgart-Vaihingen during peak hours in order to offer passengers additional alternatives. A new express bus line X60 will run every 15 minutes between Leonberg and Stuttgart University.

Preparatory measures and future challenges

Preparatory construction sites will be set up in June and July in anticipation of the S-Bahn main route closure. In order to keep the systems modern, theDigital nodes Stuttgartwith theEuropean Train Control System (ETCS)equipped. A modernization of the S-Bahn tunnel is also planned, which affects all lines.

However, the construction work is not limited to the main route. Additional track renewals on the airport route as well as work on the Gäubahn and on the control and safety technology in Stuttgart-Feuerbach are also planned. The railway also informs passengers about the possible use of electronic timetable information and the DB Navigator.

For the coming year 2026, experts expect a further, probably tighter main route closure, which is already being planned. A special task force for the Gäubahn and the S-21 project will be created to minimize the impact on rail traffic and optimize passenger information.

Overall, this is a comprehensive project to modernize the S-Bahn infrastructure, which is of great importance for the future of the transport system in the region. The measures are intended to help improve safety and efficiency for all users.
