history
The train designed by LOWA in Werdau in 1952 was the first prototype of an open-plan car for the Berlin tram. Externally, the two cars were based on the ET 50 , which was also designed by LOWA. The railcar was given the car number 8001 II , the sidecar the number 3001 II . The car had a length over sheet metal of 14,590 mm with a pivot spacing of 6,700 mm, a width of 2,500 mm and a height of 3,055 mm. The floor height was 835 mm (center). The car had three doors, the rear double folding door (1320 mm wide, clear width 1220 mm) had two steps (380, 350 mm), the middle double folding door had three steps (380, 230, 225 mm), and the front was a single-width folding door (800 mm, clear width 710 mm) with two steps as available at the rear. The railcar was intended for 40 seats, 56 standing places and a conductor's seat .
At 2.50 meters, the combination was around 30 centimeters wider than the other Berlin vehicles. In order to still enable a test use, the bank tram was converted accordingly, with the tracks in the road surface being moved apart and a turning loop at the Grünau S-Bahn station was set up. Since their delivery to BVG-Ost on November 30, 1953, they have operated exclusively on line 86E between Grünau and Schmöckwitz . The use of the open-plan cars did not last too long due to their width. In addition, the LOWA trams were made of folded profiles and were generally not designed for a long service life, so that the two cars were parked on them for a short time and finally scrapped in 1969.
With the TDE 58 , the concept of the open-plan car was resumed in the GDR at the end of the 1950s.
