- The Gäubahn continues to suffer significant punctuality and operational disruptions; Deutsche Bahn reports the line was not continuously passable on roughly 30% of days in 2024 and forecasts 7–8% affected days for 2025/2026.
- Construction in the second half of February 2026 increased travel times to about 90 minutes instead of roughly 50 and required replacement bus services between Böblingen and the main station.
- Nighttime engineering work around Horb causes train cancellations with substitute transportation during the period from 20 February into mid‑March, adding strain for regular travellers.
- A review of 500 Stuttgart–Zürich trips revealed severe punctuality failures—only about 15% on time in Stuttgart, roughly 20% in Singen and 40 trains not arriving—prompting SBB scrutiny, while Green transport spokesman Matthias Gastel calls for a thorough renovation and an expedited two‑track upgrade of the southern section instead of many isolated construction sites.
It is particularly important that the southern part of the Gäubahn finally be expanded to double track.— Matthias Gastel, transport policy spokesperson for the German Greens, calling for the southern section of the Gäubahn to be expanded to two tracks.
