Citadis

Family of low-floor trams and light rail vehicles From Wikipedia, the free encyclopedia

Citadis is a family of low-floor trams and light rail vehicles built by Alstom. As of 2025, over 8,000 Citadis trams have been ordered, with operations in over 140 cities on all six inhabited continents.[1] An evolution of Alstom's earlier TFS vehicle, most Citadis vehicles are made in Alstom's factories in La Rochelle and Valenciennes, France,[2] and in Barcelona, Spain,[3] and Annaba, Algeria.[4][a]

Types

The Citadis family includes both partial and fully low-floor trams and LRVs. Several versions are of the multi-articulated design, with alternating wheeled and suspended sections. These are built with three (20x), five (30x), seven (40x), and nine (50x) sections. The whole line-up includes the following standard variants:

  • Citadis X01 (first generation)
    • Citadis 301 – three section, 70% low floor (Orléans)
      • Citadis 301 CIS – 100% low floor version with IPOMOS bogies on 1,524 mm (5 ft) gauge (Moscow, Saint-Petersburg[5]). Also designated 71-801 according to the Russian unified system of rolling stock classification (71=trams, 8=manufacturer code (Alstom), 01=model code).
    • Citadis 401 – five sections, 70% low floor (Montpellier and Dublin, some converted from 301s)
  • Citadis X03 (third generation)
    • Citadis 403 – seven sections, 100% low floor (specially ordered for Strasbourg)
  • Citadis X04 (fourth generation)
    • Citadis 304 – 100% low floor, next generation design for Central and Eastern Europe (Istanbul)

Light-rail transit vehicles

Power supply

Like most trams, Citadis vehicles are usually powered by overhead electric wires collected by a pantograph, but the trams in several places do not use pantograph current collection entirely.

The most popular solution is Alstom's proprietary ground-level power supply (APS, first used in Bordeaux and subsequently in Angers, Reims, Orleans, Tours, Dubai, Rio, Barcelona, and Sydney), consisting of a type of third rail which is only powered while it is completely covered by a tram so that there is no risk of a person or animal coming into contact with a live rail. On the networks in France and in Sydney, the trams switch to conventional overhead wires in outer areas,[12] but the Dubai vehicles are the first to employ APS for its entire passenger length (although they are still equipped with pantographs for use in the maintenance depot).

Another option is to use on-board batteries to store electrical power, allowing brief periods of catenary-free operation without the need to install special infrastructure. The Citadis trams in Nice operate off a set of nickel metallic hydride batteries in two large open spaces where overhead wires would be an eyesore.[13][14] This has since been superseded by a supercapacitor-based energy storage system (SRS)[15] which is in use in Rio de Janeiro (alongside APS), Kaohsiung, and along a new line in Nice. The Regio-Citadis can also be built as a dual-voltage or electro-diesel vehicle with various configurations.
