Two-rooms-and-a-bath car (or multi-articulated tram) [1] is a type of tram or streetcar with one or more suspended sections. The shortest examples consist of three sections; so called car bodies. The sections at the ends each have two axles or four wheels. The centre section is suspended between the end sections, spanning like a bridge. The centre section has no wheels and appears to be floating or suspended. [2]
In 1892 a patent was registered by inventors Brewer and Krehbiel. The next year one streetcar was built for Cleveland. Only starting in 1912, a series was built for Boston. [3]
The first city in Europe to use this type of tram was Gothenburg: ten were used in service from 1922. Other cities followed but with only one or two pieces: Oslo (1924), Dresden and Leipzig (both in 1928), Amsterdam and Milan (both in 1932). In Milan and later also in other Italian cities several series were put into service. Whereas in the United States the high floor version was only built before the Second World War, it became a success in Europe and mostly in Germany. [3]
The ′classic trams/streetcars′ (with a regular high-floor and steps at the doors) came in at least three variants: the end sections can each be supported by two, three or four axles. The last variant was used twice in Düsseldorf during the 1960s. [4]
The low-floor trams come in two variants: the end sections can each be supported by two or four axles. Most low-floor trams have more than three sections. Trams/streetcars with five sections—of which three with wheels and two sections floating—are most common. Though less widespread, this type can consist of seven or nine sections: nine section trams only run in Budapest and Dublin.
A bogie is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached or be quickly detachable. It may include a suspension component within it, or be solid and in turn be suspended ; it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung, or held in place by other means.
The PCC is a tram design that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design, and many remain in service around the world.
The Siemens Combino is a low-floor tram produced by Siemens Mobility. The first prototype was produced in 1996 at the Duewag works in Düsseldorf; the trams are now made in Krefeld-Uerdingen.
The Siemens Avenio is a low floor tram family produced by Siemens Mobility, a subsidiary of the German conglomerate Siemens. It is the successor to the Combino family. The first generation was sold as the Combino Supra, Combino MkII, or Combino Plus. With the introduction of the second generation in 2009 the Combino brand was dropped and Siemens have referred to Combino Plus trams in Almada (Portugal) and Budapest (Hungary) as part of the Avenio range.
A low-floor tram is a tram that has no stairsteps between one or more entrances and part or all of the passenger cabin. The low-floor design improves the accessibility of the tram for the public, and also may provide larger windows and more airspace.
The Socimi Eurotram (later sold as the Bombardier Flexity Outlook (E)) was an electric tramcar designed for the tram system of Compagnie de Transports Strasbourgeois (CTS). Initially produced by Socimi, after the company became bankrupt Eurotrams were manufactured first by ABB Group's transportation division, then by Adtranz and finally by Bombardier Transportation, who marketed the tram as part of their Flexity Outlook range.
The ADtranz low floor tram was introduced in the 1990s as the world's first tram with a completely low floor design. This tram was developed by MAN for the Bremen urban transport system. The prototype, tram number 3801, was first publicly introduced on 9 February 1990. From 1991 to 1993, it was being tested in many European cities. Ten German cities have purchased this type. Adtranz took over the rail division of MAN in 1990.
Jacobs bogies are a type of rail vehicle bogie commonly found on articulated railcars and tramway vehicles.
Germany has an extensive number of tramway networks. 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.
The Tramway Français Standard (TFS) is a type of tram designed and manufactured by Alstom for use on various tramway systems in France. The TFS is no longer in production, having been superseded by the Alstom Citadis range of tramcars.
The Tram 2000 is a type of tram vehicle that was originally designed for the Verkehrsbetriebe Zürich (VBZ), the municipal transport operator of the Swiss city of Zürich, and first introduced in 1976. Other variants of the type were subsequently built for the VBZ, for other Swiss operators, and for the Italian city of Genoa. The last vehicles to the design entered service in 1994, but the type is still in front line service with all its original users.
The Munich tramway is the tramway network for the city of Munich in Germany. Today it is operated by the municipally owned Münchner Verkehrsgesellschaft and is known officially and colloquially as the Tram. Previous operators have included Société Anonyme des Tramways de Munich, the Münchner Trambahn-Aktiengesellschaft, the Städtische Straßenbahnen and the Straßenbahn München.
Inekon Trams, a.s. is a manufacturer of trams, or streetcars, located in the Czech Republic, and has supplied new trams to several cities in the Czech Republic and the United States. The company also carries out modernisation and repair of trams, as well as track reconstruction. It is a joint-stock company.
The CAF Urbos is a family of trams, streetcars, and light rail vehicles built by CAF. The Spanish manufacturer CAF previously made locomotives, passenger cars, regional, and underground trains. In 1993, CAF started building trams for Metrovalencia, with the delivery of 16 trams until 1999. This was a variant of a Siemens design and some components were delivered by Siemens, including bogies and traction motors. This design was also sold to Lisbon Trams in 1995; CAF then decided to design and build the Urbos in-house.
The Green Mover Max was the first 100% low-floor articulated Light Rail Vehicle (LRV) to be built entirely in Japan. It was developed jointly by Kinki Sharyo, Mitsubishi Heavy Industries, and Toyo Denki, and introduced first in Hiroshima by the Hiroshima Electric Railway Company (Hiroden). It replaced Hiroden's ailing fleet of Siemens Combinos in 2005.

The Inekon 12 Trio is an articulated low-floor tram manufactured by Inekon Trams in the Ostrava factory. Production is performed in cooperation with the city transport company of Ostrava. The 12 Trio is a double-ended (bi-directional) version of the Inekon 01 Trio tram. The 01 Trio is conceptually based on the Škoda 03 T developed by Škoda Transportation and Inekon Group. While the 01 Trio Tram is operated on the local market in the Czech Republic, the 12 Trio model was designed for export. The standard model is designated as 12 Trio, but in 2012–13 Inekon introduced a variant that is capable of limited operation on batteries only, and this is designated 121 Trio. As of 2016, the 121 model has only been purchased by Seattle.
