China's Ministry of Railways (MOR) has modified its original $4bn contract with Bombardier's Chinese joint venture Bombardier Sifang, signed in 2009.
The order modification will not change the value of the contract, under which Bombardier Sifang was to deliver 80 very-high-speed (VHS) trains, which included 20 eight-car trainsets and 60 sixteen-car trainsets.
The order has been changed to 70 eight-car Bombardier Zefiro 380 trains, 46 Zefiro 250 stainless-steel trains and 60 Zefiro 250NG trains.
Bombardier said that the variation contract will provide the MOR with increased flexibility in delivering its passenger services.
The new Bombardier Flexx Speed bogie has been developed especially for the Zefiro 380 trains, which will be powered by Mitrac propulsion and control systems, as well as Eco4 energy-saving technology, with maximum attainable speeds of 380km/h.
The company launched its Eco4 technology package in 2008.
Bombardier Sifang's production plants in Qingdao, China, will be responsible for manufacturing the Zefiro 380 trains.
Bombardier Zefiro 250 design is already in service, with 115 trains that total 1,200 cars currently in operation. The Zefiro 250NG is a development of the Zefiro 250, designed to meet the future demands of the Chinese rail market.
Zefiro 250NG will feature a new aluminium car body for reduce weight, as well as improved traction systems, optimised aerodynamics and lower energy consumption.
