EuroCity, InterCity, and InterCity Express trains connect Frankfurt with all German cities and many major European ones. The InterCity Express line links Frankfurt with Berlin, Hamburg, Munich, and a number of other major hubs. All long-distance trains arrive at and depart from the Hauptbahnhof, and many also stop at the long-distance train station at the airport. Be aware that the red-light district is just northeast of the train station.
