Unmatched capacity

Our light-rail solutions are highly flexible and can be configured to match changing passenger levels. Due to the vehicle modularity, it can fulfil the capacity needs of any urban environment by adding additional modules to the existing vehicles at a later point in time. The trams can also be coupled to form longer trainsets in multiple units, enabling an overall capacity of more than 20,000 passengers per hour, per direction.

A revelation for passengers

Alstom’s light-rail solutions have been designed to delight the passenger. Tall windows offer a wide view of the city, while the ergonomic seats, pleasing materials, climate control and real-time passenger information displays ensure a comfortable and convenient ride. Wide doors allow smoother passenger exchange at each stop and therefore lower dwell time, and the low floor throughout the vehicle enables both accessibility and easy movement within the vehicle.

Making cities safer: collision prevention & driver assistance for light rail vehicles

Putting safety first

Extensive experience in active and passive safety technology is reflected in the tram design, which sets new standards in safety performance. ODAS, the world’s first homologated obstacle detection assistance system, assists tramway drivers in critical situations by detecting obstacles and avoiding collisions. Developed to make urban transport even safer, it can be installed or retrofitted on Alstom and non-Alstom trams.

With Alstom’s collision and overspeed monitoring and prevention system, COMPAS, trams operate at a safe speed and brake automatically, preventing collisions. This vision-based system provides greater safety for passengers, drivers and road users.


Battery-powered version for emissions-free transport

Alstom leads the industry in offering a complete range of catenary-free solutions proven, in commercial passenger service, to be reliable and giving optimised energy consumption. The Citadis B on-board solution gives fully autonomous operation between stops and blends seamlessly into the urban environment.
