Tatra T6A2

T6A2 is a type designation for vehicles of the manufacturer CKD Tatra tram in Prague. The T6A2 was built between 1988 and 1999, a total of 256 developed railcars and 92 sidecar (type B6A2 ).

Types

As T6A2D the car was in the German Democratic Republic (from 1990 Federal Republic of Germany ), as T6A2H delivered to Hungary as well as T6A2B to Bulgaria.

Striking for the vehicles of the T6 series is the thyristor ( TV3 ), which enables not only a spot-on acceleration and braking, but also more energy efficient than the accelerator control of the predecessor types T3 and T4. Strikingly, the chirping sounds of electronic traction and braking in the thyristor.

T6A2

The T6A2D ( the code letter "D" was awarded only after the commencement of production of T6A2H and T6A2B to distinguish ) is the last of CKD Tatra developed for the GDR type of streetcar. He comes to the family, T6, the sixth line of development of the manufacturer. The cars were offered along with the matching sidecar B6A2D. Were supplied the vehicles to Rostock, Berlin, Leipzig, Magdeburg and Schwerin. Schwerin gave his 3 big trains from without use to Magdeburg, as the local AC for 2.5 m wide trams is designed, but the T6A2 are only 2.2 m wide.

Prototypes T6A2/B6A2

The projects for the prototypes of the type T6A2/B6A2 were confirmed in early 1982 by the Ministry of Transportation. The two built Generous (Tw Tw Bw ) were first tested in 1985 in Prague and then in Dresden. A delivery of production vehicles to the city of Dresden was not, however, the city retained the two prototypes. After 1989 a Großzug for city tours was rebuilt and used. The second Großzug remained in regular service (primarily on the line 3). In 2002, the trains were scrapped. What remains of the first prototype railcars remained 226 001 (Ex - city tour), he was the Tram Museum Dresden passed and returned to the factory setting of 1986. Characteristic of the prototypes was the line number cube on the roof, on the one then abandoned in the series deliveries.

T6A2D

After Leipzig, the first T6A2 arrived on 20 October 1988. It was the. Delivered to the GDR 4000 Tatra cars. In Leipzig he was given the number 1001. Prior to the first test drive the car was repainted in cream white, the following car (Tw 1002 Bw 802) were already wearing the new Leipzig coloring olympia blue / ivory. The vehicles were converted for city tours - they were upholstered seats and carpeted floors. In 1989, followed by other vehicles, the line began operation on 14 February 1990. By early 1991, the vehicles were delivered, then came the turn of the end for the purchase of Tatra cars. Due to the status as a splinter genus began in late 2006 in favor of the older Tatra T4D -M secondment. They were modernized only slightly in their use of time. On 30 November 2007, the adoption of the line service was. The railcars 1001 and the sidecar 801 now belong to the inventory of historic vehicles. In March 2011, all T6A2 were sold to the museum cars 1001 and 801 to an intermediary and scrapped from the end of March.

Berlin received his T6A2 1988-1991. Again, the procurement was abruptly ended by the turn. 1992 began the modernization of T6A2 analogous to KT4D. They were fitted with among other things, new interior and exterior swing doors as well as the " sun yellow " paint job. The cars were adopted according to BVG ( Berlin Transport Services ) due to increased maintenance costs on 6 December 2007 from the service line. This led primarily by the passengers from the south -east of Berlin to protest, because there were the cars, which always drove previously in double traction, replaced by solo vehicle of the type KT4D, which meant that the capacity by 1/3 fell. All trailers were parked in 2002. 32 of the most recently parked Berlin railcars have been sold to Stettin and are used there since 2008.

Magdeburg received his 3 big moves in 1989, another three originally delivered to Schwerin multiple units ( initially red - painted yellow ) followed in 1990. Between 1995 and 1997, all vehicles were extensively modernized and repainted in the new MVB color scheme. Last detained after the departure of a vehicle accident or 11 railcars and 6 sidecar in scheduled service, while unneeded T4D/B4D be scrapped. 2009 were purchased from Berlin 12 modernized sidecar, of which 11 were set after extensive revision and adaptation of the electronics since March 2011 in stages. These sidecars are used exclusively with the low-floor articulated railcar NGT8D the first delivery series, so that they can be used on Großzug courses now, which were formerly frequented only Tatra cars. The T6A2 series until January 2013 in regular service in use and was formally proclaimed from the service on January 27, 2013. A Großraumzug will remain in the museum depot.

Rostock received in 1989 and 1990, the new T6A2 with the matching sidecar. 1995 to 2001 the railcars were modernized to T6A2m. The vehicles received this swing-out doors, new interior, new headlights and a new heating system. From 1996 B6A2D - trailers were parked and replaced by Niederflurbeiwagen type 4NBWE Bombardier in this context. The trailers were sold to Szeged 2005.

In Germany, the vehicles in various combinations can be used: as a solo vehicle, as double traction (Tw Tw), as a mini - (Tw Bw ) or Großzug (Tw Tw Bw ). The control also technically possible combination Tw Tw Tw was indeed used by the BVG in Berlin in the early 1990s isolated at night transfer trips, but never used in passenger service.

T6A2H

The Hungarian city of Szeged initially ordered three railcars for their tram. They fell from 1997 on through her painting. In 1998, the fleet was increased by a further ten railcars. Now they are gradually supported by Potsdam and Cottbus KT4D, also came six B6A2D from Rostock to Szeged, which were converted to guided railcars without cab and form with the T6A2H tractions.

Also on the way are the vehicles of the type T6A2 as T6A2B in the Bulgarian capital Sofia. While the new 1435 mm network run the larger T6B5 - car, first - T6A2 40 railcars were delivered for the old 1009 mm network in 1991, the design was inspired by the Budapest T5 cars. 1999 17 and seven more cars were again passed to the operation in two sections. They made the last vehicles produced this type dar.
