The public transport of Eindhoven consists of more than 20 city bus lines, which also serve neighbouring villages such as Veldhoven, Geldrop and Nuenen. Seven of these buslines (400–407) are marketed as high quality public transport and run with 43 electric articulated busses. Two specially built separated busways (HOV1 & HOV2) are used by lines 401 to 406. Line 401 to the airport runs almost completely on separated busways. Apart from the city lines there are some 30 regional and rush-hour lines.
