The Frankfurt Airport Train: Fly downtown, too.
Why not skip the airport taxi lines (not to mention the expense) when the Frankfurt Airport Train is so convenient? You’ll be whisked into Frankfurt with direct service from the airport to Frankfurt Main Hauptbahnhof (also known as the Main Station) in just over 10 minutes. Travel comfortably in air-conditioned, non-smoking trains from Frankfurt airport so convenient, they have four departures every hour. Of course, you’ll find a reverse trip from Frankfurt’s main station to the airport just as practical.
As an added bonus, if you have a German Rail Pass or Eurail pass that includes Germany, you can use one of your travel days for free travel on the Frankfurt Airport Train.
