Improved orientation: New line number S7 introduced with the timetable change

From December 2025

Starting Sunday, 14 December 2025, we will introduce the new line designation S7 – not a new S-Bahn line, but a new name. The advantage for you: You can immediately see which S-Bahn runs on which route.

The trains between Bergedorf/Aumühle and Altona, which travel towards Altona via the City Tunnel and Jungfernstieg and return via Holstenstraße, Sternschanze and Dammtor (on the connection line), will in future carry the line number S7.

The S2 will run from Bergedorf via the connection line towards Diebsteich and back along the same route.

Why are we introducing the line number S7?

Up until now, all S-Bahn trains on the Bergedorf route had the line number S2, even though they served different routes and destinations. One travelled through the City Tunnel via Jungfernstieg to Altona, while the other went via the connection line through Dammtor to Diebsteich.

With the new line designation S7, you can immediately identify the route by the train number, making it easier to find your way around the S-Bahn network.

When does each train run?

The number of trains and the frequency on the route between Bergedorf/Aumühle and the city centre will remain the same.

In future, the S7 will be the main line on the Bergedorf S-Bahn route. From Monday to Friday during peak times, the S2 will provide additional services for the five-minute intervals.

A tip for night owls:

Night services at the weekend will continue to be operated by the S2, as you know it. It will run every 20 minutes in both directions via Dammtor, Sternschanze and Holstenstraße. One operable track between Altona and Holstenstraße is sufficient for this.

Wish of many passengers

The reason for the change in the route is the closure of the track from Holstenstraße to Altona since this summer. DB InfraGO is currently conducting investigations at the Holstenstraße railway overpass.

To ensure stable and reliable S-Bahn operations, we have responded to the changed situation and to the wishes of many passengers by adapting the route.

With the S2 and S7, there is now a clear designation of which S-Bahn takes which route. This is not a new line, but a new designation for the existing routes.

From 14 December, the S7 will be shown on train and station displays as well as in digital timetables and apps. New signs and notices will gradually be introduced at the stations.

What happens next?

As long as the track between Holstenstraße and Altona remains closed, the numbering of the Bergedorf S-Bahn with S2 and S7 will be maintained.

We will keep you updated on developments and inform you in good time when there is any news.

If you have questions, then we have the answers:

Here we have compiled the most important questions and answers for you.

1st question

The S7 (from 14.12.2025) is not a new line, but a new designation for the route between Bergedorf/Aumühle and Altona. The reason for the changed route is the closure of the track from Holstenstraße to Altona since this summer.

2nd question

Many passengers requested a clear designation for the different routes on the Bergedorf S-Bahn line. With the new line designation S7, you can see the route directly from the train number and therefore have better orientation in the S-Bahn network.

3rd question

The S7 runs from Aumühle/Bergedorf towards Altona via the main station through the City Tunnel, stopping at all tunnel stations (Jungfernstieg, Stadthausbrücke, Landungsbrücken, Reeperbahn, Königstraße). From Altona, it continues on the connection line, stopping at the stations Holstenstraße, Sternschanze and Dammtor.

The S2 serves as additional capacity: it runs during peak times from Bergedorf to Diebsteich via the connection line (Dammtor, Sternschanze, Holstenstraße) and back along the same route.

4th question

When we introduced the new S-Bahn network in December 2023, we discontinued two-digit line designations and are maintaining this rule.

5th question

Due to the longer route through the City Tunnel, the timetable for the S2 was already adjusted in the summer. The new S7 will adopt this timetable exactly. The changes compared to the previous timetable (before the Holstenstraße closure) – usually departures two minutes later – apply in both directions between Aumühle and Altona. This offset remains in place all day from Aumühle. Departure from here and in Bergedorf is always at minute 8.

From Altona to Bergedorf/Aumühle, the S7 will run from Monday to Friday between 05:54 and 19:44, with the additional two minutes. At other times on weekdays and at weekends, the S7 will depart from Altona at the old timetable on minute 2. This ensures that transfer times between S-Bahn and bus services remain unchanged, especially during off-peak hours.

6th question

Due to the two-minute shift in the S7 timetable in both directions, some direct connections from the S7 to U-Bahns and buses during the day will no longer be possible. However, since the connected lines run at short intervals, there will only be minimal increases in journey times.

Outside peak times from Monday to Friday and at weekends, the S7 can run towards the suburbs with its old timetable, so connections, especially in the Bergedorf/Reinbek area, will still be met. The change towards the city centre is due to the train order in the City Tunnel, where the S1 and S2 lines run one after the other.

7th question

The new routes and the S2 and S7 designations will remain in place until the track from Holstenstraße to Altona is once again available for S-Bahn services.
