Berlin S-Bahn Airport Disruption: Alternative Routes to BER Until August

Introduction

If you are flying in or out of Berlin Brandenburg Airport (BER) before the end of August 2025, your usual S-Bahn journey to the airport is currently not an option. Engineering and construction works have suspended S-Bahn services on the airport route, causing disruption for commuters, travellers, and expats across the city. While this is a temporary situation, it requires some advance planning — particularly if you have an early flight or are arriving late at night. The good news is that reliable alternative train options exist and are clearly signposted. This guide explains what is disrupted, what alternatives are available, and how to avoid unnecessary stress at the start or end of your journey.

What Exactly Is Disrupted?

The S-Bahn lines that normally provide a direct rail connection between central Berlin and BER Airport — primarily the S9 and S45 — are not operating on the airport section due to ongoing track or infrastructure works. These lines are a popular choice for travellers because they connect directly to key central stations and run frequently throughout the day.

The disruption is in place until the end of August 2025. After that point, normal S-Bahn services are expected to resume. Deutsche Bahn and the BVG (Berlin's public transport authority) are managing the works and have communicated that alternative services are in place for the duration.

Alternative Trains to BER Airport

The disruption to S-Bahn services does not mean you are stranded. Two regional train services continue to operate normally to BER and serve as the primary alternatives:

• RE7 (Regional Express 7): Runs between Berlin Hauptbahnhof and BER Airport Terminal 1-2, stopping at key stations including Berlin Ostbahnhof and Berlin Südkreuz. Frequency and journey times are comparable to the S-Bahn for many travellers.
• RB14 (Regional Bahn 14): Also serves BER Airport and connects through central and eastern Berlin stations.

Both services are covered by the standard BVG/VBB zone AB+C ticket (the same ticket zones required for the S-Bahn airport journey), so you do not need to buy a special ticket if you already have a valid zone ticket. The Deutschlandticket is also valid on these regional services.

Bus replacement services (Schienenersatzverkehr) may also operate on parts of the S-Bahn route, but for airport journeys the RE7 and RB14 are faster and more reliable choices.

Practical Tips for Travellers

• Add extra time: Regional trains can be busier than usual during the disruption period. Allow at least 15–20 extra minutes compared to your normal travel time.
• Check live departures: Use the BVG app, DB Navigator app, or the BER Airport website for real-time departure information before you leave home.
• Buy tickets in advance: If you do not have a Deutschlandticket or monthly pass, buy your airport ticket via the DB or BVG app to avoid queues at the station.
• Early flights: If you have a very early morning flight, double-check that your chosen alternative train departs early enough. Night bus services (Nachtbus) from BVG also serve the airport when trains are not running.
• Taxi and rideshare: As a backup, taxis and rideshare apps (Uber, FreeNow) are available at all major Berlin stations and throughout the city.

Who Is Most Affected?

This disruption is particularly relevant for:

• Expats commuting between Berlin and other cities via BER on a regular basis.
• Newcomers to Berlin who are not yet familiar with the alternative rail network and may default to S-Bahn out of habit.
• Families travelling with luggage, for whom a smooth, direct rail connection matters most.
• Anyone arriving at BER for the first time who has pre-planned an S-Bahn connection from the airport.

If you are picking someone up from the airport, make sure to share this information with them before they land — the disruption affects arrivals as much as departures.

Frequently Asked Questions

Is the Deutschlandticket valid on the RE7 and RB14 to the airport?

Yes. Both the RE7 and RB14 are regional train services operated within the VBB network, and the Deutschlandticket is valid on all regional and local public transport across Germany, including these routes. You do not need to buy a separate airport ticket if you hold a valid Deutschlandticket.

When will S-Bahn services to BER resume?

According to current information, S-Bahn services to BER Airport are expected to resume at the end of August 2025. Check the BVG website or DB Navigator for the exact restart date as it approaches, as engineering works can sometimes be extended.

Conclusion and Next Steps

The S-Bahn disruption to BER Airport is an inconvenience, but it is entirely manageable with a little forward planning. Stick to the RE7 or RB14, leave a few extra minutes, and check live departures before you set off. Normal S-Bahn service is expected to return by the end of August. In the meantime, keep the DB Navigator or BVG app on your phone and bookmark the BER Airport transport page for updates.
