Frankfurt’s S6 rail line gets a major upgrade with faster, more frequent trains

A major upgrade to Frankfurt’s S6 rail line has been completed, bringing faster and more frequent services. Trains will now run every 15 minutes between Frankfurt-West and Bad Vilbel. The improvements follow years of construction, including track expansions and station renovations.

Hessian Minister of Economic Affairs and Transport Kaweh Mansoori confirmed the upgrade has significantly enhanced the line’s capacity and reliability.

Work on the S6 line began in 2017 with the addition of two extra tracks between Frankfurt-West and Bad Vilbel. The expansion aimed to reduce congestion and improve service frequency. Between February 2023 and February 2024, the project required multiple full closures to complete critical upgrades.

From December 15, S6 trains will also stop at the newly built Frankfurt-Ginnheim station. This station will serve as a key transfer point, allowing passengers to switch to U-Bahn lines 1 and 9 at Niddapark station.

Renovation work at Niddapark U-Bahn station, originally set to begin in 2023, has now been delayed until March 2025. The plans include raising platforms and installing elevators to make the station fully accessible by mid-2026. Once complete, the station will function as a fully accessible interchange between U-Bahn and S-Bahn services.

The next phase of the project will focus on modernising the Bad Vilbel–Friedberg section. Further details on timelines and specific improvements for this segment have not yet been announced.

The completed upgrades mean passengers can now expect more frequent trains and better connections. The new Frankfurt-Ginnheim station opens on December 15, while Niddapark U-Bahn station will become fully accessible by mid-2026. Further enhancements along the Bad Vilbel–Friedberg route are still in planning.
