Arabelle Solutions, formerly GE Alstom Nuclear Systems, or GEAST, for ‘GE Alstom’, most of which was spun off from GE Steam Power, is a French multinational specialising in nuclear activities related to steam turbines (Arabelle) for the turbine islands. It is present in nearly 16 countries including China, Finland, India, Romania and the United Kingdom, and headquartered in Nanterre, France. At Belfort, it is developing the Arabelle nuclear turbine, the most powerful in the world.

Historically based in France, notably at its Belfort site, it has been a subsidiary of EDF since 31 May 2024. Originally a joint subsidiary named GE Alstom Nuclear Systems (GEAST) between General Electric and Alstom, it became an 80%-owned subsidiary of General Electric, then of GE Vernova, in October 2018. The French state held a 20% stake in GEAST. Headed by Frédéric Wiscart, GE Alstom Nuclear Systems also brought together GE Steam Power's nuclear activities, resulting from the acquisition of Alstom Power in 2015, through its two subsidiaries GE Steam Power Systems (formerly Alstom Power Systems) and GE Steam Power Service (formerly Alstom Power Services).

Bełchatów Power Station is a coal-fired power station near Bełchatów, Poland. It is Europe's largest coal-fired power station as well as the most toxic one. The power station is owned and operated by PGE GiEK Oddział Elektrownia Bełchatów, a subsidiary of Polska Grupa Energetyczna.

In 2011, a new 858 MW unit was commissioned. increasing the station's total capacity to 5,053 MW. The new unit has an efficiency rating of approximately 42%, contributed to reduction of both fuel consumption and emissions compared to the older units. The unit has been built by Alstom. Alstom also has modernized the low pressure parts in all 12 turbines and, in 2009, PGE and Alstom signed a contract to modernise unit 6. After modernization of other units, the total installed capacity reached 5,420 MW in 2015. In 2017, the electrical capacity of Elektrownia Bełchatow was increased to 5,472 MW. The plant's current achievable capacity is 5,102 MW. In the second half of 2019, the achievable capacity was reduced due to the decommissioning of the oldest unit (unit No 1).

The Maryland Area Rail Commuter (MARC) is a commuter rail system in the Washington–Baltimore area. MARC (reporting mark MARC) is administered by the Maryland Transit Administration (MTA) and operated under contract by Alstom and Amtrak on track owned by CSX Transportation (CSXT) and Amtrak. In 2024, the system had a ridership of 4,187,100, or about 19,300 per weekday as of the third quarter of 2025, less than pre-COVID-19 pandemic weekday ridership of 40,000.

With trains on the Penn Line reaching a maximum speed of 125 miles per hour (201 km/h), MARC has the highest top speed of any commuter railroad in the United States.

Thalys (French: [talis]) was a brand name used for high-speed train services between Paris Gare du Nord and both Amsterdam Centraal and German cities in the Rhein-Ruhr, including Aachen, Cologne, Düsseldorf, Duisburg, Essen and Dortmund, both via Brussels-South.

Thalys was created out of a political ambition formalised in October 1987 to establish a network of international high-speed railway services between the cities of Paris, Brussels, Cologne and Amsterdam. The Thalys name was created in January 1995. The company procured a fleet of Alstom-built TGV trains to operate its services as they were viewed as the only existing rolling stock suitable to the task.

The Régiolis is a category of multiple unit train built by Alstom coming from the Coradia family. The first train was presented on July 4, 2013, in Aquitaine, and the first commissioning took place on April 22, 2014, on the TER Aquitaine network, more than a year behind the initial schedule.

AirTrain JFK is an 8.1-mile-long (13 km) elevated people mover system and airport rail link serving John F. Kennedy International Airport (JFK Airport) in New York City. The driverless system operates 24/7 and consists of three lines and nine stations within the New York City borough of Queens. It connects the airport's terminals with the New York City Subway at the Howard Beach station in the eponymous neighborhood, and with the Long Island Rail Road and the subway in the Jamaica neighborhood. Alstom operates AirTrain JFK under contract to the airport's operator, the Port Authority of New York and New Jersey.

A railroad link to JFK Airport had been proposed since the 1940s. Various plans surfaced to build a JFK Airport rail connection until the 1990s, though these were not carried out because of a lack of funding. The JFK Express subway service and shuttle buses provided an unpopular transport system to and around JFK. In-depth planning for a dedicated transport system at JFK began in 1990 but was ultimately cut back from a direct rail link to an intra-borough people mover. Construction of the current people-mover system began in 1998. During construction, AirTrain JFK was the subject of several lawsuits, and an operator died during one of the system's test runs. The system opened on December 17, 2003, after many delays. Several improvements were proposed after the system's opening, including an unbuilt extension to Manhattan. AirTrain JFK originally had ten stations, but the Terminal 2 stop was closed in 2022.

Italo - Nuovo Trasporto Viaggiatori S.p.A. (Italian for 'New Travellers' Transport') is an Italian open-access train operating company operating in the field of high-speed rail transport under the brand name Italo (IPA: [ˈiːtalo]), stylized as .italo.

Commencing services in early 2012, it became Europe's first private open access operator of 300 km/h (190 mph) high-speed trains. NTV was created in 2006 as a privately owned high-speed rail operator. In January 2008, the company ordered 25 Alstom Automotrice à grande vitesse (AGV) trainsets, which formed NTV's initial fleet. Despite intentions to begin services in late 2011, the launch of passenger operations was postponed to April 2012 due to lengthy certification processes. On 28 April 2012, NTV conducted its first service. In its first year of operation, 2 million passengers used NTV's trains. By 2016, annual ridership reached 11 million, taking market share from competing airlines and state-owned incumbent Trenitalia. Further trainsets of Alstom's Pendolino family have also been procured, as well as coordination with bus operators, as measures to expand NTV's service coverage.

The TGV (French: [teʒeve] ; train à grande vitesse, [tʁɛ̃ a ɡʁɑ̃d vitɛs] , 'high-speed train') is France's intercity high-speed rail service. With commercial operating speeds of up to 320 km/h (200 mph) on the newer lines, the TGV was conceived at the same period as other technological projects such as the Ariane 1 rocket and Concorde supersonic airliner; sponsored by the Government of France, those funding programmes were known as champion national ('national champion') policies. In 2023 the TGV network in France carried 122 million passengers.

The state-owned SNCF started working on a high-speed rail network in 1966. It presented the project to President Georges Pompidou in 1974 who approved it. Originally designed as turbotrains to be powered by gas turbines, TGV prototypes evolved into electric trains with the 1973 oil crisis. In 1976 the SNCF ordered 87 high-speed trains from Alstom. Following the inaugural service between Paris and Lyon in 1981 on the LGV Sud-Est, the network, centred on Paris, has expanded to connect major cities across France, including Marseille, Lille, Bordeaux, Strasbourg, Rennes and Montpellier, as well as in neighbouring countries on a combination of high-speed and conventional lines. The success of the first high-speed service led to a rapid development of lignes à grande vitesse (LGVs, 'high-speed lines') to the south (Rhône-Alpes, Méditerranée, Nîmes–Montpellier), west (Atlantique, Bretagne-Pays de la Loire, Sud Europe Atlantique), north (Nord, Interconnexion Est) and east (Rhin-Rhône, Est). Since it was launched, the TGV has not recorded a single passenger fatality in an accident on normal, high-speed service.
