Alstom – Leading the Way in Smart and Sustainable Mobility

Alstom is a global innovator in smart and sustainable mobility, shaping the future of transportation through a comprehensive portfolio of solutions tailored for modern rail systems. Headquartered in France and present in over 70 countries, Alstom serves national rail operators, urban transit authorities, infrastructure owners and freight businesses with cutting-edge rolling stock, signalling technologies, digital platforms and turnkey systems. The company is committed to decarbonising transport and improving urban mobility by delivering systems that are efficient, reliable and environmentally responsible.

With over 150 years of rail expertise and a deep focus on innovation, Alstom has become a preferred partner for complex transport projects across continents, including high-speed rail, automated metros, tramways and integrated mobility networks.

Rolling Stock: From High-Speed to Urban Light Rail

Alstom offers one of the most comprehensive portfolios of rolling stock in the rail industry. Its solutions span the full spectrum of rail mobility – light rail vehicles, metros, suburban and regional trains, high-speed and very high-speed trains and locomotives.

Each train is engineered for performance, comfort and energy efficiency. For example, the Avelia high-speed train family includes models like the Avelia Liberty (designed for the US market) and Avelia Horizon (for Europe), delivering lower lifecycle costs and reduced energy consumption. Meanwhile, the Coradia family of regional trains includes zero-emission options like battery-electric and hydrogen-powered trains, supporting greener mobility in non-electrified areas.

In urban environments, Alstom’s Citadis trams and Metropolis metros enable cities to meet rising demand with vehicles that are accessible, modular and highly customisable.

Signalling: Safe, Intelligent Control for All Rail Networks

Alstom designs and delivers signalling systems that increase network capacity, ensure passenger safety and streamline operations. It supports mainline, urban, freight and mining applications with solutions that meet the highest safety and interoperability standards.

For high-speed and conventional rail, Alstom deploys ETCS (European Train Control System) and national legacy systems to ensure safe, interoperable train operations across borders. In urban transit, its Urbalis CBTC (Communication-Based Train Control) enables driverless and semi-automated operations, increasing frequency and efficiency while reducing headways.

Alstom’s signalling systems also include integrated train protection, interlocking, control centres and wayside equipment – delivered with lifecycle support to ensure long-term reliability and compliance with evolving regulations.

Components: A Comprehensive Portfolio for All Rolling Stock

Alstom develops and supplies the industry’s broadest range of components, designed to support both Alstom-built and third-party rolling stock. Its offering includes bogies, traction systems, train control and information systems, interior solutions, braking systems and HVAC units.

Each component is developed with a strong emphasis on standardisation, maintainability and environmental performance. For example, Alstom’s advanced traction systems improve energy efficiency while reducing noise and maintenance needs. Modular interior designs allow operators to tailor layouts to different service levels or passenger demographics.

These components are also available as standalone products or as part of refurbishment and upgrade programmes for fleets in mid-life or end-of-life phases.

Infrastructure: Supporting the Backbone of Rail Systems

In addition to rolling stock and signalling, Alstom provides turnkey infrastructure services that cover the full lifecycle of railway assets. This includes track laying, electrification systems, power supply and electromechanical installations in stations and depots.

Whether delivering new-build projects or upgrading legacy infrastructure, Alstom ensures seamless integration between physical assets and digital systems. The company also specialises in electromagnetic compatibility (EMC) and environmental impact management, helping customers achieve operational and sustainability goals.

Digital Mobility: Connected, Data-Driven Operations

Alstom’s digital mobility solutions bring together data analytics, connectivity, automation and cybersecurity to enhance rail operations. These platforms empower operators to move from reactive to predictive maintenance and from analogue control to digital command centres.

Flagship solutions like HealthHub™ and TrainScanner™ use IoT-enabled sensors to monitor train components in real-time, reducing downtime and maintenance costs. Meanwhile, platforms like Mastria™ offer multimodal traffic orchestration, helping cities optimise passenger flows across rail, bus, and shared mobility networks.

Alstom also delivers secure cyber-resilience frameworks for rail operators, recognising the growing threat of digital attacks on critical transport infrastructure.

Turnkey Systems: Fully Integrated, End-to-End Delivery

Alstom is a global leader in turnkey transportation systems, offering the full suite of engineering, procurement, construction and systems integration services. This model integrates rolling stock, signalling, electrification and depot equipment with lifecycle support under a single contract.

Turnkey capabilities have been proven in large-scale projects such as the Riyadh Metro (Saudi Arabia), Dubai Metro (UAE) and Guadalajara Metro (Mexico). These systems are delivered on time and within budget, with long-term maintenance and service agreements to ensure sustainable operations.

Sustainability: Naturally Alstom

Sustainability is embedded into every layer of Alstom’s strategy. The company is accelerating the shift to carbon-neutral mobility through innovation in hydrogen, battery-electric, and recyclable materials. Its EcoDesign approach aims to cut emissions, reduce noise, and improve recyclability from the earliest design phase.

Alstom’s solutions help cities and regions meet their climate targets while expanding access to clean, safe, and inclusive transport. By integrating environmental responsibility into all operations and products, Alstom contributes directly to the decarbonisation of mobility worldwide.

On 29 January 2021 Alstom acquired Bombardier Transportation. Consequently, Bombardier’s portfolio of products and services is now part of the Alstom Group.
