SHANGHAI Shentong Metro Group has awarded Alstom and its local joint venture Shanghai Alstom Transport Electrical Equipment (Satee) a €37m contract to supply new traction equipment for trains operating on Shanghai Metro lines 3 and 4. The work is due to be completed by 2014.

Alstom and Satee will equip 210 metro vehicles used on both lines with its Optonix traction system which utilises the latest IGBTs as well as lightweight motord all of which is housed in a single roof-mounted unit. The system is designed to maximise energy returned to the grid through regenerative braking, reducing the need to use mechanical over electrical brakes, and offering acceleration of 1m/s² up to 40km/h. Alstom says that Optonix is a generic platform that can be tailored to an individual customer's needs and will be the standard traction equipment in its next-generation metro platform. It can also be retrofitted to its own and other manufacturers' vehicles.

Line 3, which runs for 40.2km and has 29 stations, is operated with Alstom's Metropolis trains which were built in cooperation with CSR Puzhen and are fitted with its previous Onix traction platform. Line 4 is a 33.7km circle line with 26 stations which is operated using rolling stock supplied by a joint venture of Siemens and CSR Zhuzhou.

Alstom and Satee also won a €26m contract in December 2011 from Qingdao Metro to equip 144 vehicles for Line 3 with Optonix when it opens in December 2014, while the system has been operational on Beijing Line 15 since December 2010. Elsewhere, Alstom has sold the system to metros in Buenos Aires and Montreal.
