Alstom Citadis - Citadis Types

Citadis Types

The Citadis family includes both partially low-floor and 100% low-floor trams, in versions with three, five, and seven sections.

The Citadis family comprises:

• Citadis 100 – three section, 70% low floor, designed and manufactured in Alstom-Konstal plant in Chorzów for the Polish market (Katowice, Gdańsk)
• Citadis 202 – double articulated 100% low floor (Melbourne)
• Citadis 301 – also three section but with 70% low floor (Orléans and Dublin).
• Citadis 302 – five carbody sections, 100% low floor (Adelaide, Lyon, Bordeaux, Paris T2, Valenciennes, Rotterdam, Buenos Aires, Madrid, Melbourne, Nice, Murcia, Barcelona, Jerusalem and Le Havre)
• Citadis 401 – five sections, 70% low floor (Montpellier and Dublin)
• Citadis 402 – seven carbody sections, 100% low floor (Bordeaux, Dublin, Grenoble, Paris T3)
• Citadis 403 – seven sections, with modified end bogie design (Strasbourg)
• Citadis X-04 – three sections, 100% low floor, designed for Central and East Europe and built in Alstom-Konstal plant (Istanbul)
• Regio-Citadis – three sections, 70% low floor (Kassel, The Hague, Salzgitter)
• Citadis-Dualis – derived from the Citadis series and adapted both to tramway lines and regional railway tracks, it will be operated by the SNCF (see below)
• Citadis Compact – 22m long, wide doors (Aubagne)

The 70% low-floor “Regio-Citadis” variant allows for tram-train operation, in which trams run also on mainline railway tracks; it is used in the German city Kassel, and has been delivered for The Hague. This train type is having possibilities of duo-powering (diesel/600 VDC, 600 VDC/1,5 kV 16 Hz or 600 VDC/Bioenergy/diesel).

The Regio-Citadis model has now been superseded by “Citadis-Dualis”, redesigned to operate on the same lines as regional trains (on the TER (Transport express régional) network) and intended for running at up to 100 km/h (62 mph), compared to 70 km/h (43 mph) for the Citadis tram), and for stop spacings ranging from 0.5 to 5 km (0.31 to 3.1 mi). 31 have been ordered (plus 169 on option ) by the SNCF at an average cost of €3.2 million per car (about $4.94 million or £2.5 million).

Like most trams, Citadis vehicles are usually powered by overhead electric wires, but the trams in Bordeaux (and in the future Angers, Reims and Dubai) use the “Aps” (ground-level power supply), a 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. In outer areas, the trams switch to conventional overhead wires.

Competitors to the Citadis include Bombardier Transportation's Flexity family (Outlook, Swift, Classic, and the Link tram-train), Siemens Combino and Avanto trams, Škoda ForCity, Ansaldo Sirio and TMK 2200 from Crotram.
