The articulated car trains (from 1934: TG 29 , most recently TG 29/38/51 ) were two articulated cars with a floating middle section that were procured for the Berlin tram . Of the two examples, car 6212 was taken out of service after the Second World War, car 6211 was still in use in the West Berlin sub-network of the Berliner Verkehrsbetriebe (BVG) until 1967 and was still able to be exhibited. Similar vehicles were delivered to Dresden (car 2501 and 2502) and Leipzig (car 1400, later Dresden 2503) in 1928 . The two wagons were the first articulated wagons to be used in Berlin and also the longest vehicles in operation during their service life.
development
To reduce the need for conductors, the BVG ordered the two articulated multiple units from Christoph & Unmack in Niesky shortly after it was founded . In terms of their capacity, the cars corresponded to about a train each with a two-axle motor car and a sidecar and, since they were continuously accessible, they should only carry one conductor. The designed as bi-directional vehicles cart possessed the platforms each have two sided sliding with an internal diameter of 750 millimeters and a double-sided sliding door 1400 millimeters clear width in the center part. In the front and rear part there were 30 seats each in the longitudinal direction and 2 + 1 in the transverse direction. The middle section had no seats due to the doors.
The cars were driven by four cardan motors, two of which were located in a rigid chassis below the front and rear sections. The pantographs were located on the front or rear part, given the length of the vehicle, two collectors were installed.
The use of the two vehicles began on February 25, 1930 on line 177 between Zoo station and Teltow (Tw 6212) and from February 26, 1930 on line 74 between Kniprodestrasse and Lichterfelde (Tw 6211). However, due to the large number of passengers, it was not possible to save a conductor, which is why the two copies remained. As the passengers were let in through the wider central door, there was a conductor in each half of the car. The technical difficulties with the cardan motors also meant that further construction was not carried out. Both cars were therefore converted for the first time in 1939, in which the cardan motors were exchanged for conventional center- bearing motors and the dual control of the TM 33 and TM 36 was taken over. After the conversion, the cars were continued as TG 29/38.
After the Second World War, car 6212 was taken out of stock due to war damage. After the separation of the BVG, car 6211 came to BVG-West in two independent administrations. In 1952, after the delivery of the two one-way TED 52 railcars, it was also converted for one-way operation in the main U-Bahn workshop on Seestrasse. The rear driver's cab was removed, the doors on the left-hand side blocked and covered with running boards, and the two pantographs reduced to a front pantograph. After the renovation, the BVG continued to run it as TG 29/38/51. Similar to the TED 52, the passenger flow in the vehicle should be optimized in the one-way vehicle. Admission should now only take place via the rear door, and passengers should be handled by a seat conductor. Since complications were expected due to the large number of passengers, which were already evident with the TED 52, the car did not initially enter regular passenger service. It was only after the conductors' seat was dismantled that it was used on line 75E from 1957, which was suitable for the use of one-way vehicles. As before, two conductors were deployed, one for each half of the car.
The vehicle remained in use until the tram was discontinued in West Berlin in 1967 and was then included in the BVG-West's historic vehicle inventory. In 1993, the Berlin Historic Transport Preservation Association took over the railcar and reserves it as an exhibit.
