Alstom Citadis

The Alstom Citadis is a family of low-floor trams and light rail vehicles built by Alstom. As of 2017^[update], over 2,300 Citadis trams have been sold and 1,800 tramways are in revenue service throughout the world, with operations in 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, Reichshoffen and Valenciennes, France, and in Barcelona, Spain, and Annaba, Algeria.^[2]

Citadis types

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

• Citadis Dualis – four or five sections, 100% low-floor LRV (operated by the SNCF,^[5] see below)
• Citadis Spirit – three or four sections, 100% low floor LRV designed for the North American market (Ottawa's Line 1, Toronto's Line 6)^[6][7][8]

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,^[9] 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metallic hydride batteries in two large open spaces where overhead wires would be an eyesore.^[10] This has since been superseded by a supercapacitor-based energy storage system (SRS)^[11] which is in use in Rio de Janeiro (alongside APS), Kaohsiung, and along a new line in Nice.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.
