RB22 directly links several Potsdam stations with the airport station below Terminal 1. Weekday, starting station and current operations matter for reliable planning.
Potsdam stations
VBB lists Griebnitzsee, Potsdam Hauptbahnhof, Park Sanssouci and Golm. The route then runs via Saarmund and Ludwigsfelde-Struveshof to BER and Königs Wusterhausen.
Frequency and restriction
VBB states an hourly daily service. The Potsdam Hauptbahnhof–Griebnitzsee section runs Monday to Friday only, so weekend travellers from Griebnitzsee need another feeder connection.
At the airport station
Flughafen BER station is under Terminal 1 on U2. For Terminal 2 follow the signs via arrivals level and add walking and lift time.
When RB22 works well
It suits station access, a matching departure and luggage you can move yourself. Have an alternative for engineering works, cancellation or a tight window.
Alternatives for bags and groups
BER2 links Potsdam Hbf and towns southeast of Potsdam. Taxi and private transfer remove the station journey. Families, companies and groups may find vehicles up to 19 passengers. Check availability and total.
