The tram type TED 52 / BED 52 is a former vehicle type on the West Berlin tram . Although only two trains - each consisting of a multiple unit and a sidecar - were built, conceptual weaknesses and difficulties in the testing of these vehicles were used as a pretext for discontinuing the tram in West Berlin .
commitment
In 1952, the BVG decided to procure two test vehicles for a modern type of tram . For this purpose, two large train sets were commissioned from DWM in Berlin. The electrical equipment was taken over by AEG and SSW , who each equipped a train. The railcars had the numbers 7000 and 7001, the sidecars the numbers 2000 II and 2001 II . They were based in the Charlottenburg depot .
On February 11, 1953, the management of the Berliner Verkehrsbetriebe applied for a loan of twelve million D-Marks for the procurement of 40 large-capacity trains and 20 double-decker buses of the type D2U , which was also approved. Problems during the testing of the new tram cars, their small number of seats and the design as one-way vehicles led to a renewed meeting of the BVG supervisory body on August 28, 1953. During this meeting, those responsible decided to use the credit in full to obtain a total of 140 Using omnibuses was associated with the constant conversion from tram to bus operation in West Berlin in the years up to 1967.
The trains were only of limited use as one-way vehicles, initially on route 75 from Breitscheidplatz to Hakenfelde . With the renovation of Breitscheidplatz, the loop ride around the Memorial Church was no longer necessary, so that from April 1, 1959, it was used on line 75E between Savignyplatz and Hakenfelde or Spandau, Markt . After the closure of lines 75 and 76 on January 24, 1966, the trains ran on lines 53 and 54 between Richard-Wagner-Platz and Hakenfelde or Johannesstift . With the closure of both lines on May 2, 1967, they were parked in Charlottenburg.
After they had been taken out of service, the vehicles were to be sold to Kassel, but this did not succeed. Instead, they came into the BVG vehicle collection in the former Britz depot . After the vehicle collection was dissolved in 1993, the 7000/2000 II set came to the DVN Berlin , which has since kept it in an exhibitionable condition at the Niederschönhausen depot . Sidecar 2001 II was sold to a private person and has been at the Schmilau adventure station since 2001 . Railcar 7001 was scrapped in 1996.
construction
Compared to the usual two-axle vehicles, the cars had a capacity that was 25 to 30 more people. The trains were designed as one-way vehicles with passenger flow. The entrance at the ends of the car therefore had a triple folding door, the middle and front exit had double folding doors.
In terms of car construction, the railcar and sidecar were largely identical. Since the trains were intended as prototypes of a larger series, different electrical equipment was installed. The 7000/2000 II set was equipped by the AEG, the 7001/2001 II set by the SSW, so the two trains could not be coupled to one another. The AEG train was equipped with a Düwag drive, in which the motor installed in the longitudinal direction drives both axles of a bogie via bevel gears . The SSW train had a single axle drive in which the wheels were driven by cardan joints . The travel switches were placed under the floor between the bogies of both railcars.
The driver's cab was separated from the passenger compartment by a closed cabin. Instead of the classic crank, starting and braking was carried out using a control lever. An auxiliary drive switch with a handbrake was located at the ends of the motor coaches and sidecars for shunting. In addition, an emergency stop switch was installed at the conductor's seat to interrupt the power supply.
The passenger compartment was paneled with wood and the interior ceiling was kept white. The red upholstered seats were mainly arranged in the direction of travel; instead of the driver's cab, the sidecar had a rear, three-part bench seat. The seats were placed in the front part of the car in a 2 + 1 arrangement, in the rear in a 1 + 1 arrangement.
The lighting was carried out in the AEG train with fluorescent tubes , in the SSW train with incandescent lamps . A warm air heater was installed in railcar 7000, while a storage heater was installed in railcar 7001. The sidecars had fresh electricity heating.
With the exception of the front railcar door, the doors were operated by the conductor. The stops could be called over a loudspeaker system with microphone at Schaffnerplatz. The departure signals could be issued independently of the driver and conductor, whereby the AEG train had an acoustic signal system, the SSW train an optical-acoustic signal system.
