Trams in Budapest
tram system

The tram network of Budapest is part of the mass transit system of Budapest, the capital city of Hungary. Tram lines serve as the second-most important backbone of the transit system after the bus network, carrying almost 100 million more passengers annually than the Budapest Metro. In operation since 1866, the Budapest tram network is among the world's largest tram networks by route length—operating on 174 kilometres (108 mi) of total route—and is the busiest in the world.
As of 2023, the tram network is made up of 35 regular lines (26 main lines and 9 supplemental lines) and the Budapest Cog-wheel Railway (signed as route 60). The system is operated by Budapesti Közlekedési Zrt. under the supervision of the municipal Budapesti Közlekedési Központ. Since 2016, the system uses the world's longest 9-sectioned articulated tram vehicle, the CAF Urbos 3/9, on route 1.
History
The early days
The first horse-tram line in Budapest was inaugurated on 30 July 1866 between Újpest-Városkapu and Kálvin tér, through Váci út. Over a year before, on 22 May 1865, the Count Sándor Károlyi founded the PKVT (Pesti Közúti Vaspálya Társaság (English: Pest Public Road Rail Tracks Company)). Horse tramlines in Buda proper soon followed, built by the competing Buda Public Road Rail Tracks Company (BKVT).

Why this record matters
The phrase “tram system” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 9, 2026. The linked authority identifier is Q785837. Authority coordinates are 47.500, 19.050. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1866, 2023, 2016 and 1865.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
