Citadis tramways

Citadis tramways are suited to all urban environments, meeting the different expectations of passengers and cities, whether the requirement is for a new tramway network or the modernisation of existing networks.

Designing the city

Alstom has capitalised on its expertise accumulated over 15 years — based on its observation of changing demand, dialogue with elected officials and customers and in-depth analysis of feedback from user communities – to offer the Citadis range, a benchmark in the tramway market. 

It is also within this context that Alstom has designed the latest evolution in tramways: Citadis X05.

A standardised solution…

Citadis is built on a platform of thoroughly proven standardised components, delivering record availability while facilitating maintenance operations (up to 11% cost reduction).


The size of the tramsets can be tailored to operators’ needs: length from 24 to 44m, the number of modules from 3 to 7 and the width from 2.4m to 2.65m.

… and customisable

The tram’s external livery, nose and interior can be customised. Citadis tramways offer maximum comfort to passengers (accessibility, ergonomic seats, cosy materials, onboard passenger surveillance and information systems, double doors at the ends improving the exchange ratio by 27%).

With or without catenaries

The Citadis can be equipped with several electric power systems. Alstom proposes APS*, its proven catenary-free solution and its new full onboard autonomy management system, Citadis Ecopack (with latest generation batteries and supercapacitors).

* APS - ground power supply, by the addition of a third rail, makes it possible to do away with overhead lines thereby preserving the city’s architectural heritage

Proven expertise

Alstom holds a strategic position in the tramway market with around 15 years of return on experience, more than 50 customers, over 2,300 Citadis trams sold and 1,800 tramways in revenue service throughout the world.

Tramways built around environmental and social concerns
