S-Bahn tunnel closure and replacement services July 29 – Sept. 9

The Stuttgart S-Bahn’s central trunk route and tunnel will be closed for six weeks — from 1:30 a.m. on July 29, 2023 until the morning of Sept. 9 — to accommodate track modernization/maintenance and the renovation of stations along the segment.

During this time, S-Bahn trains will not serve the stations at Stadtmitte, Feuersee, Schwabstrasse, Universität, or Österfeld, and will stop on the upper (oben) level of the main station/Hauptbahnhof (Hbf) instead of the usual underground platform (tief). The S-Bahn will also be running a modified route network during the closure, which takes place during the traditional summer vacation period in Germany.

The way to the replacement (SEV) bus stops serving stations affected by the tunnel closure are clearly marked with directional lines on the ground and bilingual signs. Photos by Bardia Khajenoori, USAG Stuttgart Public Affairs.

Two replacement bus services will offer regular connections between affected stations:

  • SEV 1 runs between Stuttgart Hbf and Vaihingen, with stops at Stadtmitte (Wilhelmsbau/Büchsenstraße), Feuersee, Schwabstraße, Westbahnhof, Universität and Österfeld (Alter Friedhof).
    • Service is approximately every 10 minutes, or 15 minutes on Sundays.
  • SEV 2 runs between Stuttgart Hbf and Westbahnhof with stops at Stadtmitte, Feuersee, and Schwabstrasse.
    • Service is approximately every 10 minutes during peak hours (6 – 10 a.m. and 3 – 7 p.m.), Monday – Friday.
  • Bus stops are marked in English and German with the line and direction the bus serves, and the way to the temporary stops are marked with colored lines on the ground from S-Bahn station entrances.

A third replacement bus, SEV 3, offers an early morning airport connection once a day, Monday-Friday, departing Stuttgart Hbf at 4:50 a.m. and arriving at the Flughafen/Messe stop at 5:18 a.m.

A double-decker shuttle train between Stuttgart Hbf, Vaihingen, and Böblingen runs approximately every 30 minutes.

The U34 U-Bahn line will also be extended from Südheimer Platz to Vaihingen during rush hour to offer additional connections. Aside from this, and additional connections being offered on some routes to meet expected demand, the U-Bahn and bus systems are not affected by this closure.

Some regional trains may have alternate start/end points due to limited capacity at the main station and on above-ground tracks not normally used by the S-Bahn.

Community members are highly recommended to use mobile apps such as DB Navigator, SSB Move, and VVS Mobil during the closure period. These apps will use the adjusted routes and schedule when determining the best way from one location to another, and also provide live information about any temporary closures or adjustments on a particular day.

The work is part of a multi-year project centering on digitizing and improving the decades-old tunnel segment to increase capacity. Summer closures began in 2021 and will also occur in 2024 and 2025.

Schönbuchbahn replaced by buses

The Schönbuchbahn will also be undergoing work from Aug. 19 – Sept. 10, and rail replacement buses will be offered.

Timetables for the replacement buses are linked here but will also be reflected in transit apps.
