Most regional fast trains bypass Potsdam on their way to Berlin. Generally, we recommend getting off at station ‘Berlin Hauptbahnhof’ and taking the regional train RE1 to ‘Potsdam Hauptbahnhof’ (Potsdam main station), which takes approximately 20 minutes.

How to get to the Research Unit in Potsdam
The AWI Research Unit Potsdam is located on the Telegrafenberg, the historic science campus ‘Albert Einstein’, South of Potsdam's city centre. From the railway station ‘Potsdam Hauptbahnhof’, a 20 minute walk takes you to the campus on the Telegrafenberg. Alternatively, a taxi takes less than 5 minutes and costs approximately 5 Euro. Local public transport in Potsdam (bus and tram), does not service the Telegrafenberg directly. There are two AWI buildings on the campus. The old one (A43) is located on the right-hand side, about 50 m from the entrance of the campus, and the new laboratory building (A45) is located about 100 m left of the campus' gateway.

Potsdam is located just southwest of Berlin, within the ‘Berliner Ring’, a circular motorway surrounding Berlin. From nearly all directions, the simplest way to Potsdam is via the ‘Berliner Ring’ (A10), exit 17 ‘Potsdam-Süd/Michendorf’, subsequently following the road B2 to Potsdam.

600 metres past the ‘Potsdam’ city limit sign, turn right into ‘Brauhausberg’ street, also signposted for ‘Landtag’. After 1.2 km, turn right again into ‘Albert-Einstein’-street (signposted ‘GeoForschungsZentrum’), which will lead directly to the entrance of the campus.

Berlin has two airports: Tegel (TXL) and Schönefeld (SXF). From any of these airports, Potsdam can be reached by public transport (see below).

Tegel (TXL) airport
From Tegel (TXL) airport take bus line X9 or 109 to station ‘Zoologischer Garten’ in Berlin, follow the signs to the regional train station, then take the regional train RE1 to Potsdam main station (‘Potsdam Hauptbahnhof’).

Schönefeld (SFX) airport
From Schönefeld (SFX) airport take the regional train RB 22 to ‘Potsdam Hauptbahnhof’. Alternatively, take the suburban train (S-Bahn) line S9. Change trains at station ‘Westkreuz’, from where the S7 goes to ‘Potsdam Hauptbahnhof’.
