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.
