Bucharest Articulated Tramcar
The Bucharest Articulated Tramcar series is a series of tram vehicles produced between 1971 and 1990 by the main workshops of the Bucharest Transit Company.
Members
The tramcar "family" features its following members:- V3A is the flagship of this series, and was the first one to be produced. Overall this was the most produced in the series and the only one in usage today.
- V3B/V3A-2S is a variation of the V3A type, which features doors on both sides and cabs at both ends, unlike the V3A with only door on one side and cab at the front. The type appeared in the mid 1980s when construction works in Bucharest frequently disrupted the traffic, so the URAC converted a few V3As into V3Bs as prototypes for future usage.
- V2A was the second standard tram of the series, appearing in the early 1980s for lines with lower passenger numbers. They were deemed surplus after 25 years of usage and later scrapped.
- V2B/V2A-2S was the 2-section variant of the V3B, at first being exclusively used for the what is now light rail line of tram 41, because at the beginning it terminated at Crângași, where a loop could not be built due to the ongoing reconstructions in the area. Eventually they suffered the same fate as the V2As, serving their last years on line 44 in Giulești that was disrupted due to works at the Basarab Overpass.
History
Soon after communism in Romania came to power, the authorities wanted to modernize the Bucharest tram network, that at the time used ancient V09 trams from the 1920s. For a while the only solutions they could come up with were the V54 trams introduced by Electroputere and the V56 trams made by the URAC. However they were not enough for Bucharest's quick expansion in the 1960s. It soon became apparent that a new type of tram was needed for the growing network. In 1968 an agreement was reached with Linke-Hoffman-Busch from Salzgitter-Brunswick, Federal Republic of Germany, that the following year a 3 section tram would be delivered and a licence would be agreed upon. Indeed, the prototype was delivered in 1969 and tested in revenue service the following years, until it was scrapped in 1991. In 1970 the tram was dismantled for an inspection, where the designers for the project would modify some of its technicalities for the V3A project. The V3A prototype was manufactured in 1971, and was presented that same year on 4 May 1971, at the 100 year anniversary of the tram operation, where it ran on the newly operated tram line 30 in the Titan neighborhood. Series production ultimately started in 1972. By 1992, the following vehicles were produced:| City | Total | Years | Numbers |

However, the V3A prototypes' fate was not as happy as it was thought. The original agreement included the local assembly of 100 CKD kits received from LHB, with the prototype to be possibly returned, should that idea had worked. However the LHB accused the ITB of having illegally dismantled and copied the designs of their tram, and that the V3A was nothing but a pirate-copy of the LHB 3501 tram. Eventually the dispute was settled and both trams could continue working in the ITB's fleet.
The most noticeable modifications made was removal of lightweight fibreglass material from the trams, thus increasing their weight from 15 to 25 tonnes, moving the third door's location in the second section of the articulated tram, the less-aerodynamic design which gave the tram a boxy-shape, compared to the round shape of the 3501 prototype, modified destination display and minor interior modifications. The axles were made by Grivița Auto Repair Works, which specialized in producing tram axles.
Eventually by the end of 1979 a total of 293 vehicles were made, and the V3A became the flagship of the ITB fleet, slowly replacing the V54s that were now modernized with electric equipment coming from the V3As and the V56s that were slowly withdrawn thanks to the introduction of the Tatra T4R trams from Czechoslovakia.
However, with the early 1980s, these trams would soon be introduced in other cities in Romania. The huge debt that had been accumulated by the Romanian government between 1977 and 1981 meant that imports were tightly restricted, meaning that importing Tatra trams was not allowed any more and fuel import restrictions meant that buses were becoming less efficient. The local authorities then turned to electrification of public transport in cities as a solution, which included the addition and expansion of trolleybus and tram networks. At the same time the Timiș 2 made in the Banat town of Timișoara had more success than the V3A, however some city councils desired to have articulated trams instead of a traction car-trailer car formation.
In 1982, a tram car named V2A was introduced, being designed for lines with smaller number of passengers, such as the tram lines in the Giulești, Berceni and Colentina neighborhoods of Bucharest. To counter the success of the Timiș 2 trams, in 1984 the V3A and V2A were finally adapted for export to other cities, the exports starting that very same year to Constanța's newly founded tram network. However the same year, Bucharest's network was soon being faced with mass demolitions that threatened the disruption of most tram lines, and the solution of temporary track relocation was not possible like the previous times when the metro works forced tram lines to detour. To answer to this issue, ITB modified a few V3A trams that were made in 1974 and 1978, and added doors on both sides and cabs at both ends. The result was called V3B or V3A-2S. The experiment was successful, however no new trams would be produced from this. In 1986, new V2B trams were produced which were similar to the V2A trams but had the same defying characteristic as the V3B did: double cabs and double doors. In 1987 the 500th V3A tram left the factory. The last tram to leave the factory was number 362 which was made in 1990.
By the 1990s, in Bucharest however, the series was becoming outdated, so a modernization project started, called "V3A-93". The prototype was finished in 1993, in time for the 100 year anniversary of electric trams which featured a parade. By the early 2000s they quickly replaced the EP/V3A trams and the Rathgeber and Duwag trams from Munich and Frankfurt, brought second hand from 1992 to 1997. The last of the original V3A trams were retired in 2007, however they were replaced with a newer tram type that was known as V3A-CH-PPC. The V3B trams were also quickly replaced with V3B-93 trams, being the last trams from the 1993 model to be made, thus making the oldest PPC trams older than the newest 1993 model trams.
The modernization was not only done by RATB's workshops, however. Because the RATB workshops were too small to modernize a lot of trams in such a short time, this meant that an agreement was reached with FAUR, which helped with the modernization between 1995 and 2004. Not only that, but various types of modernizations were experimented. For example, a special type of modernization, known as M2000 was developed for the reconstruction of the light rail line 41. These featured bumpers, a red front paint and high-speed pantographs. Electroputere modernized a few trams between 1997 and 2002, 3 of them featuring Holec electric equipments, etc.
The end of the V2A trams started officially in 2004 when a few older trams were retired, however starting from 2008 the official withdrawal began due to their age and old technology they used, being replaced with V3A-CH-PPC trams, with the last ones' operation ending in 2010. Also in 2010 the last V2B trams were retired, being replaced with a V3B-10 variant what was not much different from the V3B-93 variant, featuring the same body as the 93 variant however featuring electrics from the 10 variant.
However, by 2013, it became clear that the modernization introduced in the 1990s was starting to show its age too. The main problem was the fact that these trams are all high floor vehicles, and despite being easy to maintain, they would have to be retired from service anyway due to non-compliance to EU transportation rules. So the same year two units were retired and modernized. The modernization is very similar to the CH-PPC variant, however the main modification was in the electric part. Here, the traction motors work on AC instead of DC, giving them the designation CA-PPC. They were trialed in 2013 and introduced in 2014. From 2016 to 2017, the official modernizations started, marking the beginning of the end of the V3A-93 era. In 2019, air conditioning systems began to be installed on 46 V3A-CH-PPC units.
Operation in other towns
Starting from 1984, the V2A/V3A family has operated outside Bucharest too, with their operation ending in 2008.Constanța
was the first beneficiary of this tram series. Their operation started in 1984, with deliveries continuing till 1990 and totalling up to 75 vehicles. They would be joined in the late 1990s by Tatra KT4D trams from Berlin. However, due to the slow closure of the network in the 2000s during Radu Mazăre's tenure as mayor, they were slowly withdrawn, with the last one being retired in 2008. Until 2012, they could still be noticed in the depot, however since then they have been scrapped.Ploiești
got these trams in 1987 and in 1988, along with a fleet of Timiș 2 trams. An interesting aspect of the fleet of Ploiești trams was that their numbers alternated, as noticed above. They were retired in the mid 2000s, replaced by Tatra KT4Ds from Potsdam.However another V3A tram exists at Ploiești. This tram was manufactured in 1998 by FAUR, and was given to the public transport company, in consideration to replace the older V3As. Eventually the plan was dropped, and the tram was kept as a unique vehicle, currently being stored due to lack of parts.
