New Delays for Stuttgart 21 Project Push Opening to 2026

Deutsche Bahn (DB) has announced further delays for the Stuttgart 21 project, a significant overhaul of the rail infrastructure in Stuttgart, Germany. Initially planned for earlier completion, the project is now expected to be fully operational by the end of 2026.

The Stuttgart 21 project, excluding the Gäubahn connection via the airport, has undergone significant timeline changes. According to the latest information from Deutsche Bahn, all major elements are expected to be functional by the end of 2026, with comprehensive testing beginning in late 2025.

Starting from late 2025, all systems related to Stuttgart 21 will enter an intensive testing phase. The new main station is scheduled to open in December 2026, ensuring full operational status of all components from day one. This decision was made to avoid partial commissioning, which was previously planned for late 2025. The goal is to provide stable and reliable timetables for passengers from the very beginning.

In March 2024, DB informed its project partners that the existing terminal station would remain in operation until 2026 due to delays in the nationwide Digital Node Stuttgart (DKS) pilot project. The current infrastructure will thus serve as the basis for the network timetable until the end of 2026.

The new main station and the transport hub in the Bonatz building will replace the old terminal station, with passenger trains starting to use the new platforms throughout 2026. The long-distance train station at Stuttgart Airport is also set to be operational by December 2026, serving trains from Stuttgart, Ulm, and Tübingen. Digital technologies will be integrated by September 2026 for the main S-Bahn line, and the Gäubahn embankment necessary for the new S-Bahn connection will be dismantled in spring 2026.

Upon completion, Stuttgart 21 will set new standards for railway hubs with its advanced technologies and improved connections. The phased implementation of this project aims to ensure a smooth transition to a modern rail infrastructure, benefiting passengers and enhancing the overall efficiency of the German rail network.
