Budapesti Közlekedési Zrt.

All of the BKV buses are wheelchair accessible. There are also a few small-sized special BKV buses, which can be reserved by phone to transport a person using a wheelchair. Metro line M4 has public lifts installed in every station. Most of line M2's stations only have escalators, excluding Puskás Ferenc Stadion, Pillangó utca and Örs vezér tere. Before its major renovation, line M3 only had elevators at Kőbánya-Kispest, but during the renovation, elevators were installed at every station. Line M1 is planned to be renovated, and equipped with elevators at every station.

Currently available regular service line with handicapped-compatible low-floor vehicles:

Metro

• line M1: Only stations Deák Ferenc tér, Széchenyi fürdő, Mexikói út (a disabled person has to ask for the operator of the wheelchair lift; lifts non-functional since at least 2009)
• line M2: Only stations Puskás Ferenc Stadion, Pillangó utca, Örs vezér tere
• line M3: All stations
• line M4: All stations

Tram

• 1: all vehicles at weekends (33-50% at weekdays)
• 3: most of the vehicles
• 4, 6: all vehicles
• 17, 19: half of the vehicles
• 24G: some vehicles in the after morning and evening peak times

Since November 2022, every bus line has low-floor buses, with trolleybus lines having low-floor buses most of the time.

• Ikarus 412: Hungarian made, 12 meters (39.4 ft) long, entirely low-floor buses; age of fleet between 20 and 22 years. The type is a serious failure, manufactured during the final decline of the Ikarus company; literally no two vehicles are identical in the 412 fleet. A number of vehicles have been already refurbished since 2009. Several engine compartment fires forced BKV to rebuild the propulsion cells and the chassis is still prone to fracture. Suffers from narrower rear door and gangway. The reduced size of the rear passenger doors can cause problems during peak hours. All of which are painted in a light shade of blue.
• Ikarus V187: One Hungarian made, 18.75 meters (61.5 ft) long, entirely low-floor, articulated bus, built in 2010. The longest bus in BKV's fleet, and also the most environmentally friendly one, fitted with a Euro-5 engine. Currently on a 3-year lease to BKV by Ikarus, though the company is considering purchasing the vehicle after the lease period ends.
• Volvo 7700: Polish made, BKV bought 38 used Volvo 7700 vehicles in 2012 to replace Ikarus 412's in the hilly routes of Buda, where they ran unreliably. (The 412's were reassigned to generally flatter areas in Pest.) These Volvos finally entered service in early 2013 and are painted in a light shade of blue officially termed "sky blue". They are equipped with automatic climate control.

  Volvo 7700A: Polish made 17.9 meters (58.7 ft) long articulated buses, based on Swedish B7LA chassis. Considered a technological marvel by experts for cramming four double doors and a usable gangway into a fully low-floor vehicle with vertically mounted engine. Current fleet of 150 arrived in three batches of fifty in 2004/2005/2006; the latest model is extremely advanced. Some passengers do not like them because of the cramped standing areas (low floor design causes slimmer standing areas), and slower run times (due to poor road conditions, especially on route 7). During their service years, they have become liked vehicles because of their higher comfort level and quietness. All of them have automatic climate control, (the first 50 was equipped with it later), which is unique to BKV's bus fleet.
• Van Hool A300: Belgian made 12 meters (39.4 ft) long low-floor buses, 13 of them built in 2000-2001 and bought by BKV in 2011. At BKV they were equipped with automatic climate control, Unlike the AG300, these have been repainted in BKV's signature blue livery. A further 49 Van Hool newA330 buses were purchased from Dijon and Lausanne, with these being powered by CNG and equipped with automatic climate control.
• Van Hool AG300: Belgian-made 18 meters (59.1 ft) long articulated bus, the articulated version of the A300. The AG300 is a special type of fully low-floor buses - the engine is located between the first and the second axles, so the third axle can be steered. 32 of them were bought by BKV in the summer of 2009 to ease the lack of modern vehicles. They were built in 2000-2001 and used in Brussels. At BKV they were equipped with automatic climate control, and were repainted into standard colors in 2013. 25 more were purchased in 2015 from Utrecht, these being the newer newAG300. Passengers noticed them for narrow inner space of the fore part, although the back has rather a large standee place.
• Mercedes-Benz Citaro: Purchased and entered service in 2012, these buses were bought used from various Western-European cities. All have been retrofitted with larger windows and the standard BKV colors. Similar buses are also owned by Volánbusz. 150 brand new Citaros were purchased in 2013, and were operated by ArrivaBus until the end of their contract, when apart from a few instructor buses, all of them were taken out of service.

• Ikarus 260: Hungarian made, 11 meters (36.1 ft) long, entirely high-floor buses; age of fleet between 28 and 36 years. Considered the "workhorse", it negotiated poor road conditions and heavy use easily, but passengers suffered a lot of noise and vibration from the under-floor mounted engine. Their age often caused concern both among laymen and experts, but their exceptionally sturdy and serviceable build allowed them to reach an age of approximately 30 years. The last remaining vehicles were taken out service in November 2022.
• Ikarus 263: Hungarian made, 12 meters (39.4 ft) long, entirely high-floor buses. A longer and more modern version of Ikarus 260.
• Ikarus 280: Hungarian made articulated version of the Ikarus 260; age of fleet between 27 and 34 years. Some of the fleet were entirely rebuilt in 1997 and painted in red-blue livery for use on 7-173 express routes, but from 2008 onwards, some of them were repainted in the standard blue. The last remaining vehicles were taken out service in November 2022.
• Ikarus 405: Hungarian made and without rear passenger doors, 7.3 meters (24 ft) long, partially low-floor midibuses for weight-restricted routes, such as the Castle District and Gellért Hill. The design was extremely compact, which resulted in a cramped passenger compartment. Equipped with fragile independent front suspension, it was prone to roll, but was still expected to run on hilly routes, for lack of a replacement. The reduced size of the front passenger doors could cause problems during peak hours. Most Ikarus 405 vehicles had tilted, 3 shade green striping painted at the front and back, except for those rebuilt in 2011 and 2012, which had blue-grey two-tone paint schemes instead. The majority had been replaced by the Turkish made Karsan Atak, partially low-floor buses. The last remaining vehicles were taken out service in November 2022.
• Ikarus 415: Hungarian made, 11.4 meters (37 ft) long, entirely high-floor buses, age of fleet between 27 and 34 years. Their rear-mounted DAF diesel engines were famous for their terrible roar, scaring passers-by, but the cab was quieter. The reduced size of the rear passenger doors on the later models could cause problems during peak hours. Almost all Ikarus 415 vehicles originally had tilted, 3 shade green striping at the front and rear, though the stripes had been removed from many of them during recent maintenance.

• Ikarus 435: Hungarian made, 17.9 meters (59 ft) long articulated version of Ikarus 415; age of fleet between 25 and 29 years. Initially equipped with pusher-type articulated drive, they suffered a lot of technical problems and struggled with chassis weaknesses until the end. The reduced size of the last pair of passenger doors could cause problems during peak hours. They were generally liked by passengers, as their 735 mm (28.94 in) high floor was lower than the Ikarus 200 series' 960 mm (37.8 in) very high floor level. Along with the Ikarus 280 and Volvo 7700A, the Ikarus 435 was the workhorse of the BKV bus fleet. It was common to see rebuilt versions around the city. These vehicles had tilted, 3 shade green stripes at the front and back, which was gradually being phased out in recent repaints, as with Ikarus 415. The last remaining vehicles were taken out service in November 2022.
• Renault Agora: Branded as "Ikarus Agora" by the manufacturer Renault-Irisbus (the owner of Ikarus at the time of purchase), this 18 meters (59 ft) long low-floor, articulated bus is not really an Ikarus, but rather a French-made vehicle rebranded to improve public perception. Only one bus is in service, given to BKV by Irisbus as compensation for delayed shipments.

ArrivaBus (formerly known as VT-Transman, later on VT-Arriva) is one of BKK's contractors running some routes with their own vehicles, but those vehicles have blue-grey painting like BKV's, and they are completely integrated in BKK system. Volánbusz and its subcontractors runs suburban lines. But they are members of Budapest Transport Organization (BKSZ), so their lines can be used by regular tickets inside the city (300s, 600s, 700s, 800s and 2000s lines).

  Solaris Trollino 4th Gen articulated trolleybus on Line 75
  Ikarus 280T: Ikarus 280 articulated body equipped with Ganz chopper-based electronics. As of July 2023, there are only 10 of these trolleybuses left in service.
• Ikarus 411/412T: The 412T is a 12 m (39.4 ft) long low floor Ikarus 412 body equipped with Kiepe electronics. Limited fleet, resulting from the collapse of Ikarus and BKV's lack of funds during the late 1990s. The similar-looking, 11 m long 411T is, however, a unique vehicle which is a couple of years older: it was an Ikarus test trolleybus, and later it was transferred to BKV as a compensation for delayed shipments.
• Solaris Trollino: Polish-made fully low-floor 12-meter (39.4 ft) buses designed as genuine ETB vehicles. They do surprisingly well on bad Budapest roads, but the fleet is limited: BKV operates only 16 of them. Following the fiscal collapse of the Ganz Transelektro Group, the local co-manufacturer the delivery of the 2nd series was delayed for several months, and was finalized by Skoda, the new owner of Ganz Transelektro. In 2015, 36 new trolleybuses arrived. 12 of them are 18 meters long, with articulated body, the others the 12-meter long version. In 2019, 21 new trolleybuses arrived.

• ZiU-9: Withdrawn from service in late 2012, these 11.8-meter (38.7 ft) Soviet-made vehicles had partial semi-low floor at the rear. The age of fleet was 28–34 years, and the vehicles suffered from rust as well as degraded insulation of the electric drive system.
• Ikarus 435T: Ikarus 435 articulated body equipped with Kiepe electronics. The last remaining vehicles were taken out of service in March 2023.
• Gräf&Stift MAN NGE-152: Low-floor, articulated trolley buses bought used from the city of Eberswalde to replace the aging ZiU fleet. The last remaining vehicles were taken out of service in March 2023.

• ICS: Abbreviation of Ipari Csuklós (English: Industrial Articulated), built by Ganz between 1967 and 1978 in Hungary, 26 meters (85.3 ft) long, high-floor, double-articulated, 8 axle tram. Nowadays, they run exclusively single, but before the modern Combino trams, they ran in pairs on lines 4 and 6. Similarly narrow-bodied as the UV type, they can be used on any BKV tram route.[5] The name "Industrial" was used to distinguish the trams from the earlier "Home-made" articulated trams (commonly known as "Bengalis", no longer in service), which were built domestically.
• KCSV-7: 30 ICS trams were re-bodied and rebuilt by Ganz-Ansaldo between 1997 and 1999, with passenger compartment heating and modernized engines. KCSV stands for Közúti Csuklós Villamos or Korszerűsített Csuklós Villamos (English: Articulated Tram for Public Road or Modernized Articulated Tram)[6]

Siemens Combino Supra tram on Elizabeth Boulevard

• ČKD Tatra T5C5: Made in Czechoslovakia from 1978 to 1984, 14.7 meters (48.23 ft) long, high-floor trams. They mostly run in pairs, apart from lines 1 and 14, where they run in triples. They are comfortable but their wider superstructure limits the lines they can serve. Nowadays, there are only a small number of these trams in their original form as most have been refurbished throughout the years. The original trams only operate on line 1.
• ČKD-BKV T5C5K, T5C5K2, T5C5K2M: From 2002 to 2004, 80 T5C5 trams went under refurbishment and were suited with up-to-date electronics, the white interior was repainted orange, and domestically made FOK-GYEM displays (flip-disc technology) were installed on the front of the trams. These displays were also installed inside the trams, and were equipped with an audible information system. Additional door opening buttons were installed inside, and on the outside of the tram. The model number of these trams became T5C5K, (the "K" stands for "korszerűsített", in English: modernized) and were not compatible with older T5C5 trams. From 2009 to 2013, these refurbished trams began to be equipped with automatic door closing, which was especially useful during winter to keep the trams warm. These trams became T5C5K2, and were neither compatible with T5C5 or T5C5K trams. Starting in 2014, the majority of the original, not yet refurbished trams, and the already refurbished, but outdated trams started to be refurbished. The electronics were improved even more from the original T5C5K, and T5C5K2, the interior was repainted in favor of a more tame, white-yellow color scheme. The outdated and often buggy FOK-GYEM displays were replaced by somewhat more modern dot-matrix displays. The trams were also equipped with BKV's FUTÁR system, which allowed the tram to communicate with BKK, and replace the displayed information on-the-fly, if needed. These newly refurbished trams became T5C5K2M, and were compatible with the older T5C5K2s, but not with the T5C5Ks or the T5C5s. The trams continued to be refurbished, and from 2016 onward, tinted windows were installed. Finally, from October 2022, apart from four trams reserved for historical purposes, all trams will be refurbished to be T5C5K2Ms. [7][8]
• Duewag TW 6000: Manufactured in West Germany between 1972 and 1973, very high floor trams, purchased in 2002 refurbished from the city of Hannover. These 28 meter (91.9 ft) long vehicles only run as singles and are noted for their extremely quiet run (which did cause some minor accidents initially). Originally designed to serve as light-rail trains, the TW6000 vehicles have a variable door-well feature, which could serve tram stops in a step-free entry configuration. This feature is much appreciated by pregnant mothers and the elderly, but so far no money has been found to build the elevated platforms required to support it.[9]
• Siemens Combino Supra: Redesigned (constructed of steel instead of the originally proposed aluminium) version of the previously controversial Siemens Combino, made in 2005–2007 in Austria, fully ultra low floor trams of a special, 54 meter (177.2 ft) long, six module design (intended only for Budapest). Up until the arrival of the newer, CAF Urbos 3 trams of Budapest, they were the longest passenger trams of the world. Currently servicing lines 4 and 6, with some servicing line 1 but only on weekends.[10]
• 

  CAF Urbos tram on Line 19
  CAF Urbos 3: After a dispute over the contract for new Budapest trams between Škoda and CAF, the latter company won the tender to supply the trams for Budapest. 37 were originally ordered, but this was increased to 47. There was also an option of a further 77 trams. 35 of the trams are 5-section 34 metre long trams for lines 3, 17 and 19, while 12 are 56 metre 9-section trams for line 1. The first arrived in Budapest in March 2015, and all were delivered by Summer 2016. The first 34-meter version entered service on line 3 in September 2015, with the first 56-meter version to entering service in March 2016 on line 1. In 2019, 26 new trams arrived, five 56-meter versions for line 1 and 21 34-meter versions, originally intended to be on lines 50 and 59/59A, but later operated on lines 17 and 19 instead. In 2022, of the remaining 51 trams, 20 were purchased, and will arrive starting summer 2024. Finally in February 2023, a government decision led to BKK purchasing the remaining 31 trams.[11] The 54-meter versions currently operate on line 1 exclusively, with the 34-meter versions operating on lines 3, 14, 17, 19, 42, 50, 59, 59A, 61 and 69, as of July 2023.

• UV, (Series "U", remote controlled "távVezérelt"): built domestically during 1956–1965, based on pre-World War II designs and without heating. These cars were quite popular among tram enthusiasts of the world. When BKV celebrated its 50 years of service, an elaborate "UV Day" parade was one of the items. They usually ran in pairs, or pairs sandwiching a trailer (some of which were built in 1939). These cars were narrower than many of the later types, so that they fit the whole network including some tunnels. Despite this, they were taken out of service in 2007, as the new Combino trams replaced the ICS trams operating on lines 4 and 6, which freed them and allowed them to operate on lines where the very outdated UV trams ran.

Cogwheel train in the Buda hills

• Cogwheel Railway: 1970s era red carriages built by SGP of Austria are currently in service, but civil organizations are pushing for their replacement as well as the reconstruction of the entire track, which is unlikely to happen in near future, because of the cost.
• MFAV (Milleniumi Földalatti Vasút, in English: Millenium Underground Railway): Domestically built double-articulated carriages from 1973 that run exclusively on line M1. Loosely based on the above-mentioned ICS tram technology, they feature three small carriages per set, in a fully low floor configuration. Likely to be replaced in the near future, MFAV vehicles are noted for high maintenance requirements, dictated by the cramped engine nacelles (needed to fit the tiny 100-year-old tunnel).
• Underground: Until 2013, both lines M2 and M3 were served by 81-717/714 and Ev/Ev3/EvA[12] 5- or 6-carriage trains of Soviet origin. These Mytishchi Factory-built metro vehicles were noisy, consumed too much power and showed a lot of wear after 25+ years of service. Nine trains were refurbished from 2000 to 2003, which gave these carriages a pink interior and aforementioned FOK-GYEM displays inside, and on the carriages, but this did not significantly improve passenger comfort. As a result, BKV bought 37 Alstom Metropolis carriages for the lines M2 and M4. There were some problems about the delivery, and in March 2010, BKV CEO István Kocsis declared that BKV may cancel the contract with Alstom because of so many delays and problems (the new carriages should have been serving on line M2 since February 2009, but they weren't yet). All soviet trains older than 30 years old (in total 43 carriages) were withdrawn from service after a serious fire broke out on line M3 which had no fatalities, but the first two carriages of the train were destroyed. (A peculiarity is that most of the withdrawn carriages were of a different type than the destroyed train, and a large quantity of them were already refurbished.) The Alstom Metropolis trains soon got the go ahead begin testings in the summer of 2012. The first train entered service on September 7, 2012 on line M2. All of the old Soviet-built metro trains on line M2 were taken out of service on April 30, 2013. Some of these were transferred to line M3 to increase capacity, but most were scrapped. All Soviet-built trains were heavily refurbished from 2016 to 2017 by Metrowagonmash. They were repainted black and white, earning the nickname "Panda", the original bench-style seats were replaced in favor of separate seats, the interior was repainted from green to white, the door-opening mechanism was replaced with a more modern one, digital LED screen were installed that display the next stations and transfer options, the control panel was also replaced completely, separators were installed between the carriages and the front of the trains were redesigned. These trains got the model number 81-717.2K/714.2K. The trains barely resembled the original ones and were originally criticized if they were even refurbished or if Metrowagonmash had just sent back new trains. In the beginning of the refurbished carriages' operation, they were very problematic. As a result, in June 2017, BKV announced, that they had submitted a severance pay demand fee of 800 million HUF ($2,343,454 USD as of 07/23). They demanded the immediate fix of said problems. In February 2019, with no result, BKV filed a lawsuit against Metrowagonmash, now demanding 6 billion HUF ($17,575,902 USD as of 07/23). In January 2020, one of the first carriages that was refurbished had to be taken out of service, as the floor panel had gotten so rusty, that BKV was afraid it was going to give in. This had to be repaired free of charge, with compensation paid by Metrowagonmash, but as they didn't pay, the lawsuit continued. The documents regarding the lawsuit were sent out in 2019 to the Russian Ministry of Justice, but Metrowagonmash only received it in June 2023. With this, BKV will be demanding 14 billion HUF ($41,020,832 as of 07/23) from Metrovagonmash.

• Massive yellow-blue trucks and orange-painted lorries are used by BKV to repair overhead wires. They are equipped with blue rotating lights and sirens and are thus authorized to ignore road traffic regulations when dealing with an emergency.
• Orange minivans and white Renault trucks are used to repair buses on site, these only have orange warning lights.
