BOMBARDIER FLEXITY SWIFT

The Bombardier Flexity Swift is a series of urban and inter-urban tram, light rail and light metro vehicles manufactured by Bombardier Transportation. 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.

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

 

Review

Vehicles in the Flexity Swift family vary in length, but are all articulated, usually with three sections. In most cases, the center section is very short, but can be replaced with a longer section in order to increase capacity. The trams can also be coupled together into trains. Nevertheless, they are all bi-directional with cabs at both ends and doors on both sides. An emphasis is placed on speed with units capable of safely reaching speeds of 80 km/h (50 mph) when running on dedicated lines.

Most vehicles typically weigh between 38.6 and 44.1 tons (35 and 40 tonnes or 34.4 and 39.4 long 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.

The Flexity Swift family comes in two distinct versions with a 70% low-floor version to allow access to those in wheelchairs without requiring the construction of high platforms in city streets and a high-floor version with level boarding at raised platforms, generally to retain compatibility with stations built for older trams or trains. 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.

Both the low and high-floor models were originally developed for use on the Cologne Stadtbahn in Germany. Other uses of Flexity Swift vehicles include London Tramlink, Manchester Metrolink, 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. The scrapped Merseytram plan for Liverpool in Merseyside planned to use the same model as London.

The Flexity Swift's closest competitors are the Alstom Citadis family (particularly the RegioCitadis, Citadis Dualis, and Citadis Spirit variants), Siemens's S70/Avanto, SD100/SD160, SD400/SD460 and S200, and Sirio from AnsaldoBreda. Compared to Bombardier's other Flexity vehicles, these vehicles are not designed for streetcar operation with extensive mixed-traffic operations, although they do operate as such on a number of systems such as in London, Manchester, and Melbourne.

Since the only example of use in the USA are the models used by Metro Transit in Minneapolis, MN, we have excluded the models used in Europe, etc.
