On 5 October 2026, Deutsche Bahn began boring the approximately 700-metre-long Wartberg Tunnel. The structure is part of the P-Option, which is preparing the northern approach for the Deutschlandtakt with additional tracks between Stuttgart Hauptbahnhof and Stuttgart-Feuerbach.
Quick overview
This report is primarily relevant for rail passengers, as it can have specific impacts on planning, connections or infrastructure. The focus is on Stuttgart 21, Wartberg Tunnel, Deutsche Bahn, Deutschlandtakt, P-Option, Baden-Württemberg, infrastructure and rail project. The key points are summarised concisely below.
Key points
- Boring of the Wartberg Tunnel (approximately 700 metres) began on 5 October 2026; of this, around 600 metres in conventional mining and around 100 metres in cut-and-cover construction.
- The tunnel is part of the P-Option with two additional tracks between Stuttgart Hauptbahnhof and Stuttgart-Feuerbach (total length approximately two kilometres).
- Branching structures in the Cannstatt Tunnel have been completed since spring 2026; construction was approved by the Eisenbahn-Bundesamt in summer 2026.
- Connection to the existing Pragtunnel (approximately 680 metres), which is being comprehensively modernised for modern rail traffic.
- Financing of the P-Option has been agreed within the federal programme under the Municipal Transport Financing Act (GVFG) between the federal government, the state of Baden-Württemberg and Deutsche Bahn (agreement in July 2022).
What this means for travelers
In the short term, little usually changes for travelers, but in the long term such projects can deliver more stable timetables, better connections and more capacity. During construction phases, diversions and temporary restrictions are possible.
Context
With the Wartberg Tunnel, a central element of the P-Option for Stuttgart 21 is being created. The additional track section between the main station and Feuerbach is intended to increase capacity in the Stuttgart node and upgrade the northern approach for the planned Deutschlandtakt.
What to watch now
- Only check specific timetable or construction notices once travel dates are confirmed.
- Allow more generous connection times for international journeys.
- Monitor the source and operator information in case dates are still provisional.
