The Bombardier C20 is a type of subway train used in the Stockholm Metro, Sweden. Between 1997 and 2004, 270 cars were delivered to Stockholm (No. 2001 to 2270) by the former Kalmar Verkstad, owned by Adtranz, later acquired by Bombardier Transportation. The C20 is a completely new design and therefore is not compatible with other train types in the system. At 46.5 metres (153 ft), each carriage is longer than the previous train types. To save cost and weight, each unit has only four bogies. The middle car has two bogies. The end parts consist of one bogie each and are connected to the central portion via a semi-trailer-direction. Trolley subframes are made of stainless steel, and are less susceptible to corrosion.

Rapid transit or mass rapid transit (MRT), also known as heavy rail, metro, subway, tube, U-Bahn or underground, is a type of high-capacity public transport generally found in urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in tunnels or on elevated railways.

Sweden, formally the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million of which 2.4 million has a foreign background. It has a low population density of 22 inhabitants per square kilometre (57/sq mi). The highest concentration is in the southern half of the country.

Kalmar Verkstad AB (KVAB) was a Swedish train and automobile manufacturer in Kalmar, Sweden that made the Tjorven and Terminal. KVAB was founded in 1902 and closed 2005 by Bombardier.

Birger Jarl (help·info), or Birger Magnusson, was a Swedish statesman, Jarl of Sweden and a member of the House of Bjelbo, who played a pivotal role in the consolidation of Sweden. Birger also led the Second Swedish Crusade, which established Swedish rule in Finland. Additionally, he is traditionally attributed to have founded the Swedish capital, Stockholm around 1250. Birger used the Latin title of Dux Sweorum which in English equals Duke of Sweden, and the design of his coronet combined those used by continental European and English dukes.

C20F

The C20F is a related prototype, built with "FICAS" technology – a highly innovative modular construction that uses a stainless steel skin bonded to a rigid composite core. This construction results in an extremely thin wall (25mm instead of the 100mm in a C20), thereby creating a more spacious interior without altering the outer profile.

The C20F has air conditioning in both the driver's cab and the passenger compartments, whereas the C20 has air conditioning in the driver's cab only. The exterior of the C20F differs by having smooth trolley sub-frames instead of the corrugated trolley sub-frames present in the C20.

Air conditioning is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals; however, air conditioning is also used to cool/dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and even to display and store some delicate products, such as artwork.

The C20F car assigned the carriage no. 2000 and originally christened Incognito. On 22 May 2012, the C20 carriage no. 2012, previously named Elvira, was renamed the Estelle on the occasion of Princess Estelle's baptism.^[1] The C20F was then renamed Elvira, and currently no car is named Incognito.

Princess Estelle of Sweden, Duchess of Östergötland, is the elder child and only daughter of Crown Princess Victoria and Prince Daniel, Duke of Västergötland. She is the eldest grandchild of King Carl XVI Gustaf, and is second in line of succession to the Swedish throne.

The C20F operates on the Green Line of the Stockholm metro.

A railcar, in British English and Australian English, is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach, with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles "railmotors".

The Stockholm Underground is a rapid transit system in Stockholm, Sweden. The first line opened in 1950, and today the system has 100 stations in use, of which 47 are underground and 53 above ground. There are three coloured main lines on the tube maps. These do however form seven actual routes. Routes number 17, 18 and 19, 13 and 14 and 10 and 11 all go through Stockholm City Centre in a very centralized metro system. All seven actual lines use The T-Centralen hub station. Apart from this central station for the metro, there exists just one other junction, the Fridhemsplan station, although both the green and red lines are mutually accessible at the Slussen and Gamla Stan stations.

The Hitachi was an electric multiple unit that operated on the Melbourne suburban railway network between 1972 and 2014. Electrical equipment was supplied by Commonwealth Engineering to designs by Hitachi of Japan, leading to their official name today, though no actual Hitachi-supplied components were used in their construction. They were the last suburban trains in Melbourne with no air conditioning, and with windows that could be opened. A total of 355 carriages were built between 1972 and 1981, including a replacement carriage for one written off while the fleet was still being delivered.

Bombardier Movia is a family of metro train built by Bombardier Transportation. The structure and body shell are fully customisable for the needs of each system that orders it. Unlike most traditional metro trains, they usually have full-width gangways between carriages, allowing passengers to walk the entire length of the train. The design was developed by Adtranz which was acquired by Bombardier in 2001.

The Pioneer III railcar was a short/medium distance coach designed and built by the Budd Company in 1956 with an emphasis on weight savings. A single prototype was built, but declines in rail passenger traffic resulted in a lack of orders so Budd re-designed the concept as an electric multiple unit (m.u.). Six of the EMU coach design were purchased by the Pennsylvania Railroad with the intention of using them as a high-speed self-contained coach that could be used for long-distance commuter or short-distance intercity travel in the Northeast U.S. The 6 production Pioneer III units were the first all stainless steel bodied EMU railcar built in North America and at 90,000 pounds (41,000 kg), the lightest.

This article outlines the history of the 24 Corten steel vehicles with corrugated sides, constructed by the South Australian Railways and primarily used on the East-West Express from Adelaide to Port Pirie. The South Australian Railways broad gauge system had been extended north in 1937 to meet a southern extension from Port Augusta on the Commonwealth Railways' standard gauge system, creating Port Pirie as a break-of-gauge and transshipment point. To encourage passengers to use the line despite the inconvenience of changing trains, in 1947 the Cafeteria Car was constructed and used on the services to and from Adelaide, in conjunction with the mid-1930s Steel carriage fleet. In 1964 the first airconditioned sitting cars entered regular service on the East-West Express, and construction of those continued through to 1967 with a total of nine sitting cars and fourteen vans.

The Type DT5 is an electric multiple unit (EMU) train type operated by the Hamburger Hochbahn AG on the Hamburg U-Bahn system. It is the first type of rolling stock on the Hamburg U-Bahn that has air conditioning and gangways between the individual cars.
