The S-Bahn (suburban rail network) line S1 operates every 10 minutes between Hamburg Airport and Hamburg’s central railway station, Hauptbahnhof, a journey of only 25 minutes. The “Hamburg Airport (Flughafen)” S-Bahn station is directly in front of the terminals and is easily reached by lift, escalator or stairs.http://www.airport.de/en/subway_suburban_rail.html
