The Hungarian capital has a great tramway network operating on more than 150 kilometres of route. There is also a metro (underground) network, which consists of four routes. It´s worth to visit the metro line M1, the Millennium Underground Railway ('Földalatti'), which was opened in 1896 as Europe's second underground railway past London and has a very small tunnel profile and appropriately small trains.
The whole public transport in Budapest is operated by → BKV
