Alstom (originally Alsthom) is a French multinational transportation systems developer and manufacturer in the field of rail transportation. The company is headquartered in France and employs 32,800 people across 60 countries. The company is diverse in that they are active in fields of public transportation, freight transportation and signalling systems.


Alstom (originally as Alsthom) was formed from a merger between Compagnie Française Thomson Houston and the Société Alsacienne de Constructions Mécaniques in 1928.

significant acquisitions included the Constructions Electriques de France (1932), shipbuilder Chantiers de l'Atlantique (1976), and parts of ACEC SA (Belgium, late 1980s). A merger with parts of the General Electric Company plc (UK) formed GEC-Alsthom in 1989.

In 1958, Alstom won its first railway project in 1958, supplying 25 locomotives to Baocheng Line, the first electrified railway in China. It is one of the first western companies, which started business in China, much earlier than the diplomatic relationship between China and France (in 1964).

In 1997, Alstom acquired Amerail - American Passenger Rail Car Company and established its US operations in Hornell, New York.

The company became, simply, Alstom in 1998. Additionally, merger of Railway Products India Limited (RPIL) into Alstom resulted in establishment of Bengaluru engineering centre operations.

In 2000, Alstom acquired Italian train manufacturer Fiat Ferroviaria, a manufacturer of trains with tilting capabilities.

In 2004, Alstom was in financial crisis due to massive inherited unexpected costs (€4 billion) arising from a design flaw inherited from the acquisition of ABB Group's turbine business, in addition to losses in other areas of the business. The company required a €3.2 billion state-backed bailout in 2003 – and as a result was required to sell several divisions including shipbuilding and electrical transmission to Nikhanj Power, in order to comply with EU rules on state aid.

In 2014, Alstom and General Electric (GE) announced that a US$17 billion (€12.4 billion) bid for the company's power and grid divisions had been made and provisionally accepted. After modification of the deal following political controversy in France relating to the take over by a foreign company of a strategic player in heavy industry, GE's bid was modified; to include joint ventures in power generation and electrical transmission, and the sale of its own rail signalling business to Alstom. The GE acquisition deal for the power and grid division was accepted by EU and US anti-competition authorities in mid 2015, subject to the sale of Alstom's heavy gas turbine business. The acquisition was finalised on 2 November 2015, with GE acquiring Alstom's power generation and electricity transmission business (combined as GE Power) leaving the Alstom company operating solely in the rail transport market.

In 2017, Alstom announced a proposed merger with rival company Siemens division Siemens Mobility, creating a new company named Siemens Alstom. If approved, the merger would be completed at the end of 2018.[1] In 2019, the European Union (EU) blocked the merger over the concerns that it could challenge EU competition rules.Amaro, Silvia.

Alstom announced in February 2020 that it had signed a Memorandum of Understanding with Bombardier and the Caisse de dépôt et placement du Québec (CDPQ) regarding the acquisition of Bombardier Transportation.[3] On January 29, 2021, Alstom announced the completion of the acquisition of Bombardier Transportation.[4]
