Product Catalogue: Components


Alstom offers an extensive range of proven and modular components for all types of railway vehicles. Continuous research and development, combined with sound validation equipment and decades of return of experience on Alstom and non-Alstom trains, guarantee that our customers will receive both state-of-the art and validated solutions. 


At the heart of train dynamics, the bogie is the key element in wheel-rail contact and braking/traction transmission. Alstom offers a variety of bogies enabling all kind of trains to operate safely with optimised passenger comfort at speeds ranging from urban to very high-speed applications.


Motors transform the electrical power from the traction system to mechanical power to get the train moving: Alstom motors enable trains to operate at speeds of up to 574.8 km/h (World rail speed record set by Alstom/SNCF and RFF on April 3, 2007).

Traction systems

Tramways, tram-trains, metros, regional trains, high-speed trains and locomotives. For over 50 years, Alstom has been manufacturing traction systems for both its trains and those from other manufacturers


Alstom offers a wide range of state-of-the-art, high quality switchgear components and associated services: contactors, isolators, DC high-speed circuit breakers, 22CBNG AC vacuum circuit breakers, vacuum contactors, changeover switches, multifunction units and energy metering systems.

Auxiliary converters

Alstom manufactures state-of-the-art auxiliary converter systems for its metros, regional trains, high-speed trains and locomotives for both its trains and those from other manufacturers.

Traction transformers

With a 50-year history and more than 5,000 liquid filled on-board transformers and inductors produced, Alstom has developed a solid track-record in designing tailor made transformer equipment for high-speed trains, regional trains and locomotives.

Cariboni feeding systems

Alstom, through its Cariboni feeding systems offer, is a leading European player in the design, development and manufacturing of components for the electrification of rail and road transport and in the market of products related to the transmission of electrical energy, particularly busbar ducts for electrical power plant, HV/MV connectors and fittings for substation, feeding system for mobile machines.

Dispen dampers

Dampers are essential to master train dynamic behaviour both for the safety and comfort of passengers. For more than 30 years, Alstom has provided customised railway dampers for bogies and carbodies suitable for all kind of trains.
