Trams in Germany

Germany has an extensive number of tramway networks (Straßenbahn in German). Some of these networks have been upgraded to light rail standards, called Stadtbahn in German. Straßenbahn and Stadtbahn schemes are usually operated on the legal foundation of the BOStrab, the Tramways Act of Germany.

Tramways served as the primary means of urban transport in Germany until the early 1960s when they were systematically replaced by buses. However, in the 1980s tramways began to reappear; experts spoke of the 'renaissance of the tramway'. In the 1990s tramways had again become a modern means of public transport. Popular notions of fashion have been used by scholars to explain this cycle of acceptance rejection and restoration.  Tramways were a highly visible manifestation of commodity culture and people projected onto them not just travel destinations but more broadly their desires, ideas and beliefs.

Stadtbahn 

The Stadtbahn is a concept dating back as far as the late 1940s, when city councils were considering Unterpflasterstraßenbahn (lit. below-pavement tramways) as part of rebuilding the city centres devastated by World War II. Some cities, like Hanover, reserved extra wide medians in their city's ring roads, though in most cities these plans never made it past the planning stage. However, seeing the success of the Berlin and Hamburg U-Bahn systems, cities started considering such schemes again in the 1960s and 1970s. Munich and Nuremberg  decided to fully abolish their trams and started constructing a full-scale U-Bahn system (although to date, neither of these has abolished their tram system and likely never will - both are in fact re-expanding their tram systems) whilst other cities, like Hanover or Stuttgart, went for a scheme of city centre tunnels and special right-of-way arrangements with the prospect of converting their tramway networks to a full-fledged U-Bahn over several decades. By the 1980s, however, virtually all cities had abolished these plans due to the high costs involved with converting the tramways, and the most common Stadtbahn systems now are a mixture of tramway-like operations in suburban and peripheral areas, and a more U-Bahn like mode of operation, featuring tunnel stations, in the city centres.

The Stadtbahn scheme is not to be confused with the S-Bahn, which commonly is a suburban railway operating under the Railways Act, while the Stadtbahn typically is an urban railway operating under the Tramways Act.

Vehicles 

The most common vehicle type currently in use in Germany is the articulated tram, either in its high floor or low floor variant. Articulated trams are tram cars that consist of several sections held together by flexible joints. Like articulated buses, they have an increased passenger capacity. These trams can be up to forty metres in length, while a regular tram has to be much shorter.

Articulated trams

History 

From 1918 on, a few prototypes were built in Germany, for example a trailer car for Dresden in 1918 and two tramcars with Jacobs bogies for Duisburg in 1926. However, interest for these cars was low and the concept of articulation fell into obscurity.

It was only after World War II that articulated cars were manufactured again; the first, small series of GT4 Jacobs bogie cars was deployed for Stuttgart in 1953 by Maschinenfabrik Esslingen.
From 1956 on, Duewag manufactured large numbers of articulated tram cars for operators in Germany and abroad to replace old pre-war models.

Starting in 1959, Maschinenfabrik Esslingen and Hansawaggon, the latter mainly in Bremen and in Munich, tried to get into the market with their Kurzgelenkwagen construction — however, in West Germany their market share remained small compared to the Jacobs bogie cars made by Düwag.
The Hansawaggon design was copied later by CKD Tatra, which manufactured large numbers of KT4D tram cars based on this design for use in the GDR.

Apart from the larger series, small numbers of cars were rebuilt for operators with odd requirements, for example the Bremer Straßenbahn AG received a series of 3-axled and Augsburg bought several 5-axled cars.

In the 1970s, the first urban railway cars were developed in the Federal territory. In some cases, tried and tested tram types were modified in such a way that they were also suitable for elevated platforms; While long-distance articulated wagons with a trajectory of curves were built for Frankfurt and Hanover, the Stuttgart tram was followed by the opposite route, although a number of Stuttgart lines were also used as a conventional tram. In their first versions, the new Stuttgart double-wagon consisted of two four-axle single-wagons without a transition, and their bogies were much further apart than with classic streetcar trucks.

In the 1990s, high-pressure low-floor trains were developed. In part, considerable changes were noticeable after large numbers of units were already in use. Also some older articulated cars were improved after 1990 with a low-floor segment. In order to avoid problems with low-floor technology, there are also new designs that are not completely low-floor, such as the Flexity Swift, developed for Cologne since 1995, whose axle distribution with four wheels is firmly developed underneath a short middle segment from a conventional articulated carriage type of the Zurich tram, the middle segment of which, however, has an exterior door. A pioneer in the development of Regiotram is Karlsruhe.

Since 2000, the low-floor technology have been increasingly improved. Since 2001, the market leader Bombardier has been producing eight-axle three-piece rather than six-axle single-axle engines. And as successor model of the ADtranz low floor tram, is the Flexity Berlin. Particularly long-range low-floor articulation trains are built for the Dresden transport companies. At a time when low-floor technology is already almost standard, on the other hand the railways as RegioTrams also use railways, tramway vehicles (increasingly known as tramway vehicles) have to fulfill contradictory requirements.

Kurzgelenkwagen 
Kurzgelenkwagen is a German term for articulated cars that require exactly one bogie per carbody. These are mostly of the GT4 type; a German acronym for an articulated (G for Gelenk = "joint") motorized (T for Triebwagen) tramcar with 4 axles. Two different models of these have been deployed:

Type Stuttgart 

The GT4, developed by Maschinenfabrik Esslingen in 1959 for the Stuttgart tramways' steep lines connects the two bogies with a girder. The car bodies support themselves by resting on their bogie and on the girder. It therefore is not possible to separate the vehicle's individual cars. 380 cars were built in total, of which 350 were delivered to Stuttgart. Further cars were in use in Freiburg im Breisgau, Reutlingen, Neunkirchen as well as Ulm and Augsburg (which bought them used from Stuttgart), after German reunification used GT4 vehicles were also used in Nordhausen, Halberstadt and Halle.

Type Bremen 

The  GT4 cars, designed and built for Bremer Straßenbahn AG, rest on the individual carbody's bogie only. The joint is not supported, and sections can be added and removed in the workshop. Hansawaggon delivered articulated power cars and trailers to the tramways of Bremen and Bremerhaven, the Munich-based manufacturer Rathgeber bought these cars under licence for the Munich tramways.

Tatra KT4 

The Czechoslovakian company CKD Tatra developed the KT4D tram car based on the same joint and bogie concept and delivered it in large numbers to the GDR from 1976. These cars, used in East Berlin and a number of other cities, were only manufactured as power cars, however they can run as multiple units.

This concept found another use in three- and four-part low floor trams built since 1989, however a special track layout is necessary for these trams, as they have the tendency to swerve in curves.
MAN and Adtranz delivered these vehicles to Bremen, Berlin, Munich and Nuremberg; Duewag built a series of 40 for Frankfurt am Main (Type R).
