The tram cars of the type U4 , which were carried under the designation T 33 U from 1934 , were a series of 60 railcars that were designed in 1933/34 by the National Automobile Society in Berlin-Oberschöneweide . Because of the division of their passenger compartment into a larger non-smoking and a smaller smoking compartment, the vehicles were also known as “living room and kitchen” cars in Berlin vernacular .
development
The cars were designed by NAG in Oberschöneweide from 1933. They were officially referred to as conversion cars, as they were created using the motors and drive switches from the previous conversion series U3l . These represent a conversion of former Berolina wagons . In contrast to the center entry wagons of the type U3M (from 1934: TM 31 U and TM 31 US), which also emerged from this type in 1931/32 , these 60 wagons again had end entrances. The division into a smoking and a non-smoking compartment was retained here as well, which ultimately led to the nickname “parlor and kitchen”. The target sign boxes integrated into the roof were also available on the TM 31 U.
The vehicles had telescopic sliding doors at the entrances. In contrast to the existing cars, the vehicles were painted chrome yellow throughout. In the mid-1930s they were given the usual light ivory paintwork with a black trim. A buzzer system and a bell pull, which could be operated from the driver's seats, served to communicate between driver and conductor. Red signal lamps on the doors were used to communicate between the motor car and the trailer.
Seven railcars were decommissioned after 1945 as war losses. The BVG (West) received 39 railcars when the Berlin transport company was separated , and the BVG (East) received the remaining 14 cars.
In the 1950s, the wagons located at BVG-Ost received simple sliding doors instead of telescopic sliding doors. The division into smoking and non-smoking compartments was abandoned and intermediate doors to the platforms were installed. In 1963 she was in the Rekoprogramm involved with and went to the railcars 5001 II -5014 II on. The cars that remained with BVG (West) were given more powerful versions with 50 kilowatts of power instead of the 40 kilowatt motors. This allowed you to drive with two sidecars covered. They were taken out of service by 1964/65 and some were sold. It is not known to what extent vehicles of the type are still available.
