It's one of the easiest ways to reach Alexanderplatz and Berlin city center if you are traveling via Berlin Schonefeld airport. The single ride ticket price is around EUR 3, and you can buy them at vending machines in tunnel connecting airport to railway station. Make sure you composter them on platform before entering the train.
