Alstom is a French multinational rolling stock manufacturer which operates worldwide in rail transport markets. It is active in the fields of passenger transportation, signaling, and locomotives, producing high-speed, suburban, regional and urban trains along with trams.
The company and its name (originally spelled Alsthom) was formed by a merger between the electric engineering division of Société Alsacienne de Constructions Mécaniques (Als) and Compagnie Française Thomson-Houston (thom) in 1928. Significant acquisitions later included the Constructions Électriques de France (1932), shipbuilder Chantiers de l'Atlantique (1976), and parts of ACEC (late-1980s).
A merger with parts of the British General Electric Company formed GEC Alsthom in 1989. Throughout the 1990s, the company expanded its holdings in the rail sector, acquiring German rolling stock manufacturer Linke-Hofmann-Busch and Italian rail signaling specialist Sasib Railways. In 1998, GEC Alsthom was listed on the Paris Stock Exchange and, later that year, it was rebranded Alstom. At the time, the company was manufacturing railway rolling stock, power generation equipment and ships.
In 2003, the company required a €3.2 billion bailout from the French government. As a result, Alstom was compelled to dispose of several of its divisions, including shipbuilding and electrical transmission to Areva, in order to comply with European Union rules on state aid. In 2004, Alstom remained in financial difficulties, having incurred massive unexpected costs (€4 billion) arising from a design flaw inherited from the acquisition of ABB's turbine business, in addition to losses in other business sectors.
In 2014, General Electric (GE) announced that it reached a deal to purchase Alstom's power and grid divisions for US$17 billion (€12.4 billion). The deal came under heavy scrutiny from French regulators who saw the business as a strategically important domestic industry.

An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail.
High-speed rail (HSR) is a type of rail network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above or upgraded lines in excess of are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964. The system also became known by its English nickname the bullet train.
