context_page_description: Rocar was a van, light truck, bus and trolleybus manufacturer based in Bucharest, Romania. The firm also produced light offroad vehicles and later heavy road vehicles. During its existence, the company produced over 350,000 vehicles.
context_section_description: T12 (1955–58) – reconstructed version of old trolleybuses.
  T.V. 2E; T.V. 20E – Mainly the same vehicle, however different in appearance. Built between 1958 and 1968 ( TV 2E) and 1968 and 1975 (TV20E). Were replaced starting in 1974 by more modern MAN based vehicles. Their technical specifications are mainly the same, but they are different in the exterior aspect. Both were 10 metres long, 87+1(T.V. 2E) passengers or 90+1(T.V. 20E) passengers capacity including the driver, 2 doors, and a 75 kW motor; top speed was 40–45 km/h. Last vehicles T.V. 20E were also built with an 85 kW motor, speed increased to 50–55 km/h. However they were modified in some cities where they were operated in parallel with DAC 112 E ROMANIA, with 125 Kw motors . It was not equipped with pneumatic suspension, it was instead equipped with leaf springs and 2 rigid axles ( however it was built on a truck chassis). The compressor was working intermittently, not continuous, as it was used solely for braking and door actuating. 15 articulated versions of this trolleybus (T.V. 2E based) were also built in 1964 (presumably by URAC- ITB) and rarely operated until 1967 by ITB but withdrawn from service, probably because of some deficiencies, high costs of manufacturing and low production capacities.  Named T.V. 2E-A, 15 metres long. About 120 passengers capacity . T.V. 2E and 20E were withdrawn from operation between 1975 and 1982, however in some cities, they continued to be used as service or driver school vehicles until early to mid 1980s.
  DAC 112 E ROMANIA – sometimes mistakenly called ROMAN 112E, was a trolleybus based on ROMAN 112UD body. Same technical specifications as Rocar DAC 212E. ROMAN 112 E name is used to differentiate it from classical DAC 112 E. Manufactured between 1975 and 1982. No articulated version. Operated in the past in : Constanta, Bucuresti, Brasov, Cluj, Timișoara, Cities with trolleybus system before 1980. They were withdrawn from service in the late 1980s and during 1990s. Built with TN76 125 kW motor, but also with a lower power version of this motor, producing 110 kW, probably economical versions.
  DAC 112 E – Trolleybus version of DAC 112 bus; Different body from DAC 112 E ROMANIA. Same specifications as DAC 212, however, DAC 112E was one of the first models, usually low height. It was available both with TN76 125 kW and TN81 150 kW motor, but also a 110 kW economical version was available. Pneumatic suspension. DAC 112 E were built in fewer exemplars than DAC 117 E which had a higher demand. Some 117E were transformed in 112 E. Some of these busses were having a contact and relays big box behind the driver, but these models were rare, however causing crowding between passengers. Top speed: 60 km/h. As a result of the harsh economy in the period it was manufactured, some of these models were not fitted with power steering, although originally designed to have power steering. Some of them were retrofitted with power steering after 1990.
  DAC 117 E/EA – Articulated, 17 m version of DAC 112E. First models were equipped with TN76 125 kW motor, but also TN81 150 kW versions existed. No 110 kW motor fitted. Many of them were low height. 36+112+1 passengers. Pneumatic suspension Some of them were later fitted with electronic choppers. Some of them were fitted with 180 KW motors, but these were modified at the owning garage, the motor being imported. Slightly lower number of passengers, because many of these vehicles were having a big contacts and relays box inside the saloon behind the driver. This is one of the particularities of DAC 117 which makes it easy identifiable. However, this big contact and relays box was also specific to some DAC 217, but to a lower extent. Top speed : 55–60 km/h.  As a result of the harsh economy in the period it was manufactured, some of these models were not fitted with power steering, although originally designed to have power steering. Some of them were retrofitted with power steering after 1990.
  DAC 122E or 123E – Double articulated trolleybus based on DAC 117E. It could transport more than 170 passe
