Eurotram

The Eurotram was an electric tramcar designed for the tram system of Compagnie de Transports Strasbourgeois (CTS). Initially produced by Socimi, after the company became bankrupt Eurotrams were manufactured by ABB Group's transportation division, later by Adtranz, and then by Bombardier Transportation, who marketed the tram as part of their Flexity Outlook range.

Eurotrams have been used on the Strasbourg tramway (France), the Azienda Trasporti Milanesi (Italy), and on the Porto Metro (Portugal).

The Eurotram light rail vehicles was originally designed for the Compagnie des Transports Strasbourgeois (CTS) specifically for use on the Strasbourg tramway; design requirements included a 100% low floor design, airconditioning, and a higher than usual power to weight ratio for the 8% gradients in the tunnel under Strasbourg's main station. The appearance was stylised by Belgian designer Philippe Neerman.

Tenders for manufacture of the tram led to contracts with ABB Group and SOCIMI (Milan, Italy); SOCIMI subsequently became bankrupt and ABB completed production alone, on the basis of SOCIMI's prototypes; the trams were manufactured at ABB's Holgate works, York and Litchurch lane works, Derby in the UK, with some parts from ABB Trazione (Italy).

The tram design was modular, consisting 2.575 metres (8 ft 5.4 in) cabs, 7.550 metres (24.77 ft) passenger units, and 2.350 metres (7 ft 8.5 in) articulation sections. The initial Strasbourg vehicles used seven modules: two cabs, three passenger units and two articulation sections, for a train length of 33.1 metres (109 ft) Each train has a mixture of powered and unpowered bogies; the bogie design used independently rotating wheels, each on a stub axle, the primary suspension was of the radial arm type, and the secondary suspension air spring type. Each wheel of a powered bogie was separately powered by bogie mounted three phase asynchronous motors, connected via a gearbox, with the wheel and motor axises of rotation parallel.
