S-Bahn tunnel between Frankfurt and Offenbach open again from Monday!

After six weeks of construction, the time has finally come: From Monday, August 16, 2025, commuters and travelers will be able to travel on the S-Bahn between Frankfurt and Offenbach again during the day. The City Tunnel, which connects the two cities, will be opened in time for the new school year. This is particularly pleasing to students and their parents who rely on a reliable connection. Loud hessenschau.de Lines S1, S2, S8 and S9 will then run regularly again between the Frankfurt Mühlberg station and Offenbach Ost.

But it won't go completely smoothly. The construction work has not yet been completed, which is why there are disruptions and diversions at night. Especially between 8:20 p.m. and 12:20 a.m., only one track between Offenbach-Ost and Mühlberg is in operation. The tunnel remains completely closed from 12:20 a.m. to 4:20 a.m. Replacement buses are available to accommodate travelers during these times.

Sanitation and security measures

The Frankfurt-Mühlheim station was completely renovated during the summer holidays. In addition, the Offenbach stations Marktplatz, Ledermuseum and Kaiserlei have received new fire protection systems. These measures are intended to increase passenger safety and strengthen the attractiveness of public transport connections. Residents of the region can look forward to better infrastructure, although construction work will last until October 20, 2025.

However, anyone planning to use the S-Bahn in the coming months should be prepared for further restrictions. The tunnel will be completely closed again during the autumn holidays. These sometimes uncomfortable circumstances require patience and flexibility from passengers, but those responsible are optimistic that the connections will soon function smoothly again.

outlook

For commuters and students, the reopening of the S-Bahn lines is a step in the right direction. The regular trips between Frankfurt and Offenbach promise not only to ease traffic, but also to be an important link for the entire region. While construction work is still ongoing, it will be exciting to see how local transport will develop in the coming months.

In the meantime, passengers can prepare to complete their daily journeys comfortably and without major detours. It is clear: local public transport in the region is on the right track, even if there are still some challenges to be overcome.
