It is part of the Bombardier Flexity family of rail vehicles, and like the others, Flexity Swift vehicles can be customized to suit the needs and requirements of customers including legacy designs from its acquisition of Adtranz.

[citation needed] Railly News reported that, by the end of 2015, more than 1,000 Flexity Swift vehicles had been sold.

Most vehicles typically weigh between 35 and 40 tonnes (34.4 and 39.4 long tons; 38.6 and 44.1 short tons), though the ones made for the Minneapolis line are heavier due to stricter crashworthiness requirements in the United States (particularly buff strength) and the vehicles in Rotterdam and Karlsruhe are also heavier due to their use on a full, high-capacity rapid transit network and on mainline railway tracks, respectively.

While they typically use DC overhead lines for power collection, the Rotterdam vehicles are also equipped with third rail power capability for use on the central sections of the network, while the Karlsruhe tram-trains are compatible with AC electrification which is used on the mainline railways.

Other uses of Flexity Swift vehicles include London Tramlink, Manchester Metrolink,[4] the tram networks in Istanbul and Melbourne, Rotterdam Metro, Karlsruhe Stadtbahn, Bonn Stadtbahn, Stockholm light rail lines 12 and 22, and the Metro Light Rail in Minneapolis-Saint Paul, Minnesota.
