Tatra T3
T3 is the name of a tram series of Czechoslovak manufacturer Tatra CKD. The T3 is a further development of the constructed according to the American system PCC T2. The T3 was built between 1960 and 1990, a total of 13,991 railcars and 122 sidecar. So the series competes with the Russian KTM -5 to the rank of the built in greatest quantity tram car in the world.
Types
T3
To the T3 following demands were made: While the car should have the same capacity as the vehicles of the predecessor type T2, but be easier. To achieve this goal, thinner walls and vehicle cushion seats made of plastic were installed, for example. The T3 has been delivered to all street railway companies of the former Czechoslovakia, the most he was represented in Prague with more than 1,000 vehicles. The T3 forms, now often modernized in various forms, in the Czech companies are still the backbone.
T3SU
Similar to the T2SU the first T3SU two were instead supplied with three doors per car. Later, the cars were, however, delivered with a third door. The vehicles had a separated cab and were adapted to the weather conditions. A total of 11,368 T3SU were delivered, which is the world's largest quantity of a single tram car.
The T3SU was delivered in 1963, first to Moscow and later in 33 other Soviet cities.
T3SUCS
In 1976, the production of T3 has been set and built newer vehicle types. 1980 was formed with two railcars for the Slovak city of Košice a first exception. From 1985 the production of the KT8D5 should start. Since this was delayed, were needed other vehicles. A production of T3 was not possible at this time, vehicles were instead re-imported and adapted by type T3SU. The closed cab was maintained, all cars have three doors and differ from the original T3 only in a few details. Traction education with the same vehicle is possible and has been and is being practiced.
T3D
In the GDR, the first three sample wagon type inverted T3 ( railcars and trailers ) in 1964 and 1965, first in Dresden. Since there due to their width of 2.5 m was the limited operation is possible, the production cars came later only with the transport companies Schwerin and Karl- Marx-Stadt used. Here it wrong as a solo railcar or in traction (Tw Tw Tw Tw Bw ) or as a mini train (Tw Bw ). The ability to sidecar resulted from the fact that with the same engines (TE 022) as the Czech original T3 equipped railcars suitable for sidecar electrical equipment and a different gear ratio received, so that the maximum speed while at 55 km / h - instead of the normal 65 km / h - decreased, but on the other hand, the pulling force is increased, which allowed to carry a sidecar.
In addition to the Yugoslav companies only German factories were equipped with a Beiwagentyp. This was referred to as B3D and corresponded in large parts of the car structural design to the T3D.
By 2005, Chemnitz sold over 40 of his old T3D into Russian Ufa The rest of the Tatra inventory was 1992/1993 extensively modernized. Currently (as of 2013) is still 10 trains (Tw Tw) in regular service.
T3YU
The vehicles produced from 1967 for Yugoslavia differed from the models of type T3 with a different arrangement of pantographs, here on the rear bogie, and partly also reduced bogies. Moreover trailers were also as in the GDR, delivered. In addition to two Czechoslovak and a Soviet operation, the vehicles were also the only narrow gauge cars of the type. They were delivered to the tram Osijek in Croatia today.
T3R
Through the CMEA Romania has also moved in the late 1960s to order Tatra cars. The first cars arrived in 1967 at the tram Galaţi and differed to the Czechoslovak vehicles by altered electrical equipment operating at 750 volts DC. Since the bodies of the other farms were built too wide, they remained in Galaţi.
