History

The first double-deck coaches in Görlitz were produced in 1935 by the wagon and machine Görlitz for the double-decker streamlined Wendezug the LBE. Three of the eight cars were from this company. After the Second World War, two - and four-part double-deck units modeled after the LBE vehicles and five -piece double-decker articulated trains were each developed in several versions. Adjustable from the experience of the poor to fluctuating demand, as not separable in operating multi-part units was begun in 1970, a new type of car, the " two-tier standard seat car ". Two prototypes were built in 1971 and introduced at the Leipzig Spring Fair in 1972 to the public. In these two cars, the entrances were for the first time in the lower floor. This resulted in a platform height of 550mm, a stepless entry, at 380 and 760 mm, only one stage is overcome. In addition, outside sliding-doors were provided. The possible thereby waiving kick boxes and door pockets simplified the box construction combined with increased rigidity and reduced susceptibility to corrosion. 1974 began series production of intermediate and driving cars. In the production period they were continuously evolving, for example, received the German Reichsbahn from 1986 car with disc brakes. The cars were also exported to Czechoslovakia, Poland and Romania in larger numbers.

After German reunification in Görlitz wagon, now as part of the German wagon AG ( DWA), working on the successor generations.

Since 2009 the cars under the name TWINDEXX be marketed. 2010 ordered the Swiss Federal Railways with the TWINDEXX Swiss Express Triebzugvariante one of the trains.
