The Budapest Transportation Company (BKV) is coordinating and managing the public transportation of the Hungarian capital. The public transportation network is advanced, most points of Budapest can be easily accessed. Public transportation vehicles run often with decreasing frequency toward the suburbs and by night. Public security is good, however, thefts may happen to careless passengers and minor incidents may also occur at night. The use of public transportation vehicles instead of car traffic is highly recommended in the daytime.
Buses usually provide fast transportation except in the rush hours, when metro and tramways are more efficient. Bus stops are located closer to each other, than metro stops. Red lines are express lines not stopping at every bus stop. Tickets have to be bought in advance except for selected lines, where you can buy your ticket also from the driver, but the tickets cost more in this case. You have to validate your ticket, after you get in. There are regular ticket checks, passengers travelling without a validated ticket will be fined. Boarding is limited to front doors at night, when the driver checks passes and tickets.
There is only one funicular in Budapest running up and down the Castle Hill offering a splendid view of Pest. Its two stations are in the Castle District and on the Clark Adam ter, respectively. The Clark Adam ter is the square at the Buda bridgehead of the Szechenyi Lanchid (Chain Bridge) and it's accessible by bus or the tramway running along the Danube.
The metro is mostly the fastest transport vehicle in Budapest. There are three metro lines in Budapest, each of them running every 2-15 minutes between 4.30am and 11.15pm every day:
M1 (yellow line)
M2 (red line)
M3 (blue line)
There is one interchange station (Deák Tér - Deák Square) between the three lines. Visit the SubwayNavigator web site for a map of the metro network and a travel time calculator.
You can buy your ticket from a ticket machine or ticket office at any metro station. The ticket must be validated before entering the metro area (usually before the stairs or the moving staircase). Keep your ticket until you leave the metro area. Ticket inspectors may ask you anywhere in the metro area to present your pass or validated ticket.
The touristically two most important suburban railway lines connect Budapest with Szentendre and Godollo. Both HEV stations can be reached by the M2 (red) metro line ('Batthyanyi ter' metro stop to Szentendre, 'Ors vezer tere' metro stop to Godollo).
