Kassel has seven tram lines (1, 3, 4, 5, 6, 7, 8), with trams arriving usually every 15 minutes. The city also operates a light-rail Stadtbahn network called RegioTram using Regio Citadis low-floor trams which run on both tram and main line railway tracks with four lines (RT3, RT4, RT5, RT9). Moreover, a number of low-floor buses complete the Kassel public transport system. The introduction of low-floor buses led to the development of the Kassel kerb which improves the accessibility at bus stops.
The city is connected to the national rail network at two stations, Kassel Central, and Kassel-Wilhelmsh�he. The traditional central station (Hauptbahnhof) has been reduced to the status of a regional station since the opening of the Hanover-W�rzburg high-speed rail line in 1991 and its station (Kassel-Wilhelmsh�he) on the high-speed line at which the InterCityExpress (ICE) and InterCity services call.
Kassel is connected to the motorways A 7, A 49 and A 44.
The city is served by Kassel Calden Airport
