Innovation first

Specifically designed to meet local railway standards wherever they are used in the world, Alstom’s bogies integrate the latest technological advances, combining operational efficiency with passenger comfort. Examples include the Flexx Urban™ bogie fitted to the 100-km/h Citadis light-rail vehicle in North America or the best-in-class lightweight Flexx Eco™ inboard bearing bogie used in metro, commuter, regional and high-speed trains. This technology enables best-in-class ride performance, optimised lifecycle cost, and provides tilting capability to the Avelia high-speed platform.

Additionally, Alstom offers innovative systems (Flexx Smart™) for level access, improved track friendliness, track monitoring (Flexx Monitor™) as well as the development of customer-optimised wheel profiles (Flexx Consult Wheel-Rail Interface Study). Innovations are driven by our two bogie competence centres, located in France and Germany.

Fulfilling customer requirements

Alstom puts a specific focus on optimising the total cost of ownership of its bogies. Its light-rail bogies are the lightest on the market, leading to reduced track wear and energy consumption, thereby allowing savings on related operations and infrastructure maintenance costs. Alstom’s bogies are easy to maintain, in particular thanks to a wide range of spare parts as well as tailored maintenance and repair services. Alstom supports customers throughout the full lifecycle of its bogies, enabling them to concentrate on their core business. Furthermore, Alstom’s network of component manufacturing centres on all five continents ensures unparalleled proximity with clients.
