BVG type code

from Wikipedia, the free encyclopedia

On December 13, 1920, the Great Berlin Tram , the Berlin Electric Trams (BESTAG) and the trams of the City of Berlin (SSB) merged to form the Berlin Tram. This went on January 1, 1929 in the Berliner Verkehrsbetriebe (BVG). Since the individual tram types of the predecessor companies, but also the vehicle fleet that had been procured in the meantime, were managed differently, the BVG introduced a type code in 1934 to identify the individual motor coaches and sidecars. The key essentially provides information about the type of vehicle and the year of construction and, if applicable, the year of conversion.

Type code

This is made up of letters and numbers. The first letter indicates whether it is a railcar (T) or a sidecar (B). This could be followed by a letter or two to specify the species. The following letters were used:

  • D - bogie car
  • F - chassis car
  • M - center entry car
  • S - car of the SSB
  • G - articulated trolley
  • E - equipment trolley
  • Z - bidirectional trolley (only used on the TZ 69 )
  • O - open entry platform

In the following, the year of development or the first year of construction was shortened. Years of renovation are indicated separated by a slash. A reference to the conversion car (U) or special design (S) could be given below.

The key was not used uniformly at the time. The existing maximum railcars were initially designated as TD (later TD 07/25 ), TDS (later TDS 08/24 ) and TDO. The cars of the rifle cars previously designated as type 1927 , however, were designated as TM 33, TM 34 and TM 36, without reference to the first year of construction. Conversion wagons were either marked with the year of conversion or with the following U, whereby the following U was mostly used for de facto new buildings.

Example:

  • T 24 : railcar, built in 1924
  • TF 13/25 : Chassis railcar, built in 1913, year of renovation 1925
  • TM 31 US : Central entry railcar, built in 1931, conversion car, special design

After the BVG split up, both sides continued to use the key. In one case, BVG-West deviated from the usual form by designating its maximum motor coaches converted into steering three-axle vehicles as the T 3 F 50 type.

Although the Berliner Verkehrsbetriebe did not use the type code with the procurement of the KT4D type Tatra wagons and took over these vehicles with the manufacturer's designation, it is now used in a slightly modified form for the existing low-floor vehicles. The wagons are marked with GT (for articulated wagons ), then the number of axles and then separated by a hyphen with the year of first construction.
