e.V (DRF) and HDM Flugservice air rescue services which operate a rescue helicopter and an intensive care helicopter, respectively. Furthermore, several ADAC air ambulances and Flight Ambulance International (FAI) are based in Nuremberg. Airlines and destinations The following airlines operate regular scheduled and charter flights at Nuremberg Airport: Annual Traffic Ground transportation Metro The U-Bahn (Metro) line U2 serves the airport at the Flughafen station. Trains connect the airport with the centre of the city every 10 minutes. The ride to the Hauptbahnhof (Central Railway Station) and the nearby Altstadt (historic old town) only takes 13 minutes. Nuremberg Airport is the only airport in Germany to be served by U-Bahn rather than S-Bahn, Tramway or Deutsche Bahn. Car Nuremberg Airport is located north of the city centre. It is accessible via nearby Autobahn A 3, which connects to Autobahn A 9 as well as Motorways A 73 and A 6. Longstanding plans for a more direct access from A3 (which runs north of the runway) were abandoned by all relevant local political factions in the run-up to the 2020 local elections. Bundesstraße 4 runs just to the West of the runway and is connected to the airport by local roads. Access for private automobiles is via Marienbergstraße and Flughafenstraße whereas public transit buses can use a slightly more direct route (see below). Bus Bus number 30 connects the airport with bus and Tram line 4 stop "am Wegfeld" before continuing to Erlangen. Since December 2015 new bus line 33 was installed, allowing passengers from Nuremberg's west-neighbouring city Fürth getting to the airport quicker without taking a detour via Nuremberg Central Station. Since the extension of Tram Line 4 from Thon to am Wegfeld, Bus line 30 which formerly terminated in Thon has been rerouted to the airport, thus offering a direct connection to downtown Erlangen from the airport for the first time. The bus takes a route through local neighborhoods which predate the airport and makes use of streets which are otherwise closed to motorized traffic, including a short stretch through the airport parking lot. During much of the day lines 30 and 33 overlap between "am Wegfeld" and the airport for a ten minute headway. Walking or cycling Because of the airport's close-in location and its direct connections to local streets, it is also possible to walk or ride a bicycle from nearby neighborhoods right up to the terminal.
