Budapest cogwheel railway (Fogaskerekű vasút) is the world’s third hill railway. It is not only common public transport regularly used by Budapesters, but also a moving tourist attraction that can take you from Moszkva tér to the Buda hills and Children's Railway, a narrow-gauge forest railway operated by children (which is the other attraction worth seeing).

The buses in Budapest are frequent and fast. There is an express service on some routes, and such express buses with red numbering travel the same route as the normal ones (numbered in black), but cut out the minor stops. The super express buses travel without stopping between termini and may be recognized by red numbering followed by a red letter E. Tickets are validated in the hand- or electronic puncher on board. Don't forget to push button next to the door of you wish to alight at the next stop. If no one is waiting at the stop and no one has signaled an intention to alight, the bus will pass by the stop.

The fifty-year-old Budapest trams are still good. They squeak and groan, but keep on running on the main radial and riverside routes on both sides of the Danube and several of the bridges. The ticket is validated by a punch- or electronic machine on board. Don't forget to push button next to the door if you want to alight.

Runs between Batthyány tér on the Buda side and Szentendre, stopping at Aquincum and the camping site/baths of Római fürdő (as well as elsewhere) en route. On the Pest side it runs from Örs vezér tér to Gödöllő, from Vágóhíd to Dunaharaszti, and from Boráros tér to Csepel.
Tickets are available at the stations.

Budapest has three underground metro lines intersecting at Deák tér:

• M1, the little yellow line from Vörösmarty tér to Mexikói út. The first subway in Continental Europe.
• M2, the red line from Déli train station to Örs vezér tere.
• M3, the blue line from Újpest-Központ to Kőbánya-Kispest.
