BER · FEX vs S-Bahn
Since the December 2025 timetable change, FEX is exceptionally fast to Hauptbahnhof, Potsdamer Platz and Südkreuz. That still does not make it the automatic winner. If you are staying near Alexanderplatz, Friedrichstraße, Zoologischer Garten or another Stadtbahn stop, a direct S9 can save a transfer.

Price does not decide it: the fare is the same
Travel between central Berlin and BER requires a Berlin ABC ticket. From 1 January 2026, the single fare is €5.00. VBB explicitly states that the regular fare applies without an airport-express surcharge. FEX is therefore not a premium train requiring a separate ticket.
Buy the correct zones before travel and check whether your ticket needs validation depending on how it was purchased. If you already hold a valid Berlin ABC day ticket or another suitable VBB product, you do not need another ticket simply because you choose FEX.
FEX became much stronger with the Dresdner Bahn
From 14 December 2025, FEX uses a direct BER → Südkreuz → Potsdamer Platz → Hauptbahnhof route. The published journey times are roughly 14 minutes to Südkreuz, 19 to Potsdamer Platz and 23 to Hauptbahnhof. VBB describes an approximately 15-minute service in the main operating period; BER notes that until December 2026 FEX and RE20 jointly provide four services per hour on this corridor.
This makes FEX the natural baseline if your hotel is near one of those stations, if you continue on a long-distance train from Hauptbahnhof, or if the Ringbahn from Südkreuz gives you an easy final connection.
S9 and S85: slower, but sometimes more direct
S9 remains the direct S-Bahn route from BER through Schöneweide and the Stadtbahn towards central and western Berlin. VBB lists a 20-minute frequency and direct stops including Ostkreuz, Warschauer Straße, Ostbahnhof, Alexanderplatz, Hackescher Markt, Friedrichstraße and Zoologischer Garten before continuing west. S85 also connects BER with Ostkreuz and northern/north-eastern Berlin every 20 minutes.
This is why the blanket advice “take FEX” can be wrong. If your hotel is five minutes from Alexanderplatz, direct S9 may be easier than a faster FEX to Hauptbahnhof followed by a platform change, waiting and another train. Compare time to the actual address, not only minutes spent onboard.
Where is the airport station?
Flughafen BER station is directly under Terminal 1 on level U2. For Terminal 2, follow the airport signs between terminals. On the return trip, budget for more than the train time: include the walk to the correct terminal, security and any temporary transport disruption.
Four real-world scenarios
Hotel beside Hauptbahnhof
Start with FEX. A longer S-Bahn journey adds little value unless the current timetable shows disruption.
Hotel beside Alexanderplatz
Compare direct S9 with FEX plus a transfer. “Express” does not automatically mean fastest to your door.
Apartment around Ostkreuz
Check S9/S85 and regional RB24/RB32. Eastern Berlin has direct BER links, so travelling via Hauptbahnhof can be unnecessary.
Connecting to an ICE at Hauptbahnhof
FEX is the logical baseline: it reaches the main station directly and reduces city transfers with luggage.
Decide in 60 seconds
- Enter your exact address, not just “Berlin city centre”.
- Check FEX via Hbf/Potsdamer Platz/Südkreuz.
- See whether S9 or S85 stops directly closer to your destination.
- Compare transfers and walking with luggage.
- Immediately before departure, check VBB for works, cancellations and night-time changes.
Our rule: FEX for Hauptbahnhof, Potsdamer Platz and Südkreuz; direct S-Bahn when it leaves you closer to the address. Both use the standard Berlin ABC fare.
