A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
A multiple-unit train is a self-propelled train composed of one or more carriages joined, and where one or more of the carriages have the means of propulsion built in. By contrast, a locomotive-hauled train has all of the carriages unpowered.
A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
Bombardier Transportation was a Canadian-German rolling stock and rail transport manufacturer, with headquarters in Berlin, Germany. It was one of the world's largest companies in the rail vehicle and equipment manufacturing and servicing industry. Bombardier Transportation had many regional offices, production and development facilities worldwide. It produced a wide range of products including passenger rail vehicles, locomotives, bogies, propulsion and controls. In February 2020, the company had 36,000 employees, and 63 manufacturing and engineering locations around the world. Formerly a division of Bombardier Inc., the company was acquired by French manufacturer Alstom on 29 January 2021.
The Alstom Metropolis is a family of electric multiple units designed and produced by the French rolling stock manufacturer Alstom. It is designed for high capacity rapid transit or metro rail infrastructure systems. Trains can be run in various configurations, the length alone varying between two and ten cars; it is also suitable for both manned or unmanned operations.
The Kawasaki Heavy Industries (KHI) C151 is the first generation electric multiple unit (EMU) rolling stock in operation on the North–South and East–West lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by a consortium led by Kawasaki Heavy Industries (KHI) under Contract 151. They were first introduced in 1987 and are the oldest trains in operation on the network.
The ICE 2 is the second series of German high-speed trains and one of six in the Intercity-Express family since 1995. The ICE 2 (half-) trains are even closer to a conventional push–pull train than the ICE 1, because each train consists of only one locomotive, six passenger cars and a cab car. The maximum speed is 280 km/h (175 mph), but this is limited to 250 km/h (155 mph) when the cab car is leading the train and even further down to 160 km/h (100 mph) when two units are coupled at the powerheads due to the forces on the overhead line by their respective pantographs.
CRRC Changchun Railway Vehicles Co., Ltd. is a Chinese rolling stock manufacturer and a division of the CRRC. While the CRV emerged in 2002, the company's roots date back to the establishment of the Changchun Car Company in 1954. The company became a division of CNR Corporation before its merger with CSR to form the present CRRC. It has produced a variety of rolling stock for customers in China and abroad, including locomotives, passenger cars, multiple units, rapid transit and light rail vehicles. It has established technology transfer partnerships with several foreign railcar manufacturers, including Bombardier Transportation, Alstom, and Siemens Mobility.
Nippon Sharyo, Ltd. , formed in 1896, is a major rolling stock manufacturer based in Nagoya, Japan. In 1996, it abbreviated its name to "日本車両" Nippon Sharyō. Its shortest abbreviation is Nissha "日車". It was a listed company on Nikkei 225 until 2004. It is listed on the Tokyo Stock Exchange and Nagoya Stock Exchange as ticker 7102. In 2008, Central Japan Railway Company became the majority shareholder (50.1%) of the financially struggling Nippon Sharyo making the firm a "consolidated subsidiary" of JR Central. In July 2012 Nippon Sharyo USA started production in their new facility in Rochelle, Illinois. The facility closed at the end of October 2018 due to a lack of orders.
CRRC Nanjing Puzhen is a Chinese railway rolling stock manufacturer, based in Puzhen, Nanjing city. It is a subsidiary of CRRC. Nanjing Puzhen has supplied trains to Shanghai Metro Line 3 and Nanjing Metro in partnership with Alstom.
The railcar couplers or couplings listed, described, and depicted below are used worldwide on legacy and modern railways. Compatible and similar designs are frequently referred to using widely differing make, brand, regional or nick names, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Transition between incompatible coupler types may be accomplished using dual couplings, a coupling adapter or a barrier wagon.
The Hitachi A-train is a family of rail rolling stock built and designed by Hitachi Rail using a common base and construction techniques. The stock is designed to facilitate a number of product life-cycle improvements including ease of manufacture, increased energy efficiency, and recyclability.
From time to time, a railway decides that it needs to upgrade its coupling system from one that is proving unsatisfactory, to another that meets future requirements. This can be done gradually, which can create many problems with transitional incompatibilities, or overnight, which requires much planning.
Taiwan Rolling Stock Company (TRSC) is a rail vehicle company. TRSC is located in Hukou, Hsinchu County, near Xinfeng railway station. It was previously a rolling stock production division of Tang Eng Iron Works before 2002. After privatization, the company received several orders from Taiwan Railways Administration and also Kawasaki Heavy Industries. For example, some vehicles of the Taipei Metro system were built by TRSC.
The MRTC 3000 class or ČKD Tatra RT8D5M LRV is a first-generation class of high-floor uni-directional light rail vehicles built by Czech tram manufacturer ČKD Tatra. The LRVs are owned by Metro Rail Transit Corporation (MRTC), operated by the Department of Transportation (DOTr) thru DOTr MRT-3, and is currently used on the Manila MRT Line 3.
Electric Multiple Units (EMU) are powered on the metro network of Athens, with five or six coaches. EMU-5s are of a former type and are limited to Line 1. On Lines 2 and 3, routes are only operated with EMU-6s. The trainsets were put into operation by STASY in 2011, with its establishment.
The LRTA 1100 class is the second-generation class of high-floor light rail vehicles of the LRT Line 1.
The Kaohsiung Metro Siemens Modular Metro (Mo.Mo) electric multiple unit (EMU) trains has operated on the heavy-rail Red and Orange Lines since its opening in 2008.
The MRTC 3100 class or CRRC Dalian 8MLB LRV is the class of second-generation uni-directional light rail vehicles built in China by CNR Dalian, now CRRC Dalian. Since its delivery, most of the trains are still being tested and undergoing final assessments, before being used on regular services on Line 3 of the Manila Metro Rail Transit System.
