High speed trainsets take shape

01 Aug 2005

Chinese Railways has ordered three fleets of high speed trains for operation of 200 km/h regional inter-city services

TO OPERATE its emerging network of dedicated passenger routes (p479), Chinese Railways expects to put into service by 2015 a fleet of 1000 trainsets designed to operate at speeds of 200 km/h or more.

Tenders are to be called next year for the very high speed trains to operate on the 300 to 350 km/h routes, but work is already underway on three fleets of 200 km/h trainsets to operate intermediate services on regional corridors and the three inter-city networks.

To support the high speed fleet, the Ministry of Railways is planning to develop four major depot and workshop complexes in Beijing, Shanghai, Wuhan and Guangzhou, each with a capacity of around 250 trainsets.

As part of the ongoing speed-up programme, CR and the China Academy of Railway Sciences have been working for several years on developing a range of locally-built 200 km/h trainsets to work on existing lines. In addition, the China Star trainset (RG 6.03 p344) was developed by a consortium of Chinese manufacturers at a cost of 100m yuan for operation at up to 300 km/h on the Beijing - Shenyang high speed line.

However, when the present Minister of Railways Liu Zhijun took office in mid-2003, the ministry's focus changed from developing domestic technology to addressing rapidly the growing bottlenecks on the railway network.

Faced with the need to build up a large fleet of high speed trains in a relatively short timescale, the Ministry of Railways decided to call international tenders for the supply of 140 trainsets, split into seven batches of 20 units. On October 9 2004 technology transfer contracts were awarded to three international consortia.

Shinkansen success

A ¥140bn contract for 60 eight-car trainsets was awarded to a consortium of Japanese companies led by Kawasaki that includes Hitachi, Itochu Corp and Mitsubishi Corp, Mitsubishi Electric and Marubeni Corp, working with the Nache Sifang subsidiary of the China Southern Locomotive & Rolling Stock Industry Co. As consortium leader, in charge of managing the overall design and manufacture of the 480 vehicles, Kawasaki's share of the contract is worth ´80bn.

The Japanese trainsets will be based on the E2-1000 Shinkansen design used by JR East for its premier Tokyo - Hachinohe Hayate services launched in December 2002. The first three trains will be supplied complete from Japan and the following six in knocked-down form. The remaining 51 sets will be assembled in China by Nache Sifang over the next two years under the terms of the technology transfer deal.

An improved variant of JR East's E2 design, the E2-1000 achieved 362 km/h during a high-speed test run on the Joetsu Shinkansen between Urasa and Niigata on April 6 2003. The design features a double-skin carbody structure and 25 kV 50Hz traction equipment. The E2-1000 driving trailers and first class car have active suspensions for 275 km/h operation, whilst semi-active suspensions are used on the remaining vehicles (Table I). VVVF traction controls and three-phase motors are fitted.

The Japanese sets have a 10-car formation with two driving trailers and eight motor vehicles, seating 814. The Chinese sets will be shorter, as an eight-car formation has been selected as standard. Two trainsets will be able to operate in multiple.

Wide-bodied Pendolino

Another 60 trainsets are being supplied by Alstom in conjunction with China Northern's subsidiary Changchun Railway Vehicles. Other Chinese companies such as Yongji are supplying subsystems for the trains which are expected to enter commercial service in 2007. Based at Beijing, the units will run on the northern routes around Beijing and Harbin.

In a similar breakdown to the Kawasaki contract, the first three Alstom trains are due to be completed in France, with parts for the next six being shipped to China for local assembly. The remaining 51 sets will be built at Changchun. Components will be sourced from Alstom's plants at Savigliano and Sesto San Giovanni in Italy and from Tarbes and Ornans in France.

The design is derived from the wide-bodied Finnish variant in Alstom's tilting Pendolino family, with bodyshells formed of extruded aluminium profiles. There will be no provision for tilt. Maximum width of the Chinese sets will be 3200mm (Table II). The air-conditioned trains will be sealed to cope with pressure pulses from two trains passing at 200 km/h in double-track tunnels. The trains are being designed to operate in temperatures ranging from -25°C to +40°C.

Each eight-car trainset will be powered by 10 underframe-mounted asynchronous traction motors, giving a total continuous rating of 5500 kW. The 6·5 kV IGBT traction controls will be water-cooled, with three transformers and five converter sets to offer a degree of redundancy. Rheostatic and regenerative braking will be fitted, and two units will be able to operate in multiple.

Styling has been placed in the hands of Giugiaro Design. Seating will be arranged 2+2 in first class and 2+3 in second class. An eight-car set will have 622 seats. There will be a mix of face-to-face seating with tables and airline-style face-to-back seats. For improved circulation, the internal and external doors will have a clear width of 800mm, as will the internal gangway and inter-car connections. Retractable steps will be fitted at each doorway.

Each trainset will include an area for passengers with reduced mobility, including a wheelchair-accessible toilet. There will also be a bar-cafe area and catering service facilities including hot water dispensers for tea making. The passenger information system includes audio and visual displays, plus external announcement facilities. As well as automated announcements, there is provision for manual broadcasts by driver or train crew members. On-train entertainment will be provided, with the first class cars featuring armrest-mounted headphone controls and drop-down ceiling-mounted video monitors.

Regina variant in the south

The remaining 20 trainsets in the initial tranche are coming from the established Bombardier Sifang Power joint venture in Qingdao, which is already building loco-hauled inter-city stock for CR. Under the US$424m order, the C2008 trainsets are due for delivery between July 2006 and July 2007, and are expected to be used on routes in the south of the country.

On June 27 this year the Ministry of Railways signed a 'strategic co-operation framework agreement' with Bombardier which provides for the purchase of additional trainsets, starting with an option for 20 more eight-car sets for delivery in 2007-08.

This accord also includes an agreement for the consortium to develop and support the Guangzhou maintenance depot able to service up to 250 high speed EMUs. The ministry will provide land for the depot, which will be designed and equipped by Bombardier. The company will also supply maintenance management services, spare parts, technical support and training over 20 years.

The C2008 trains are being designed at Västerås in Sweden, where some of the propulsion equipment will be manufactured. Bogies will come from Bombardier's Siegen plant, and the trains will be assembled by BSP at Qingdao. The design is a development of the wide-bodied Regina EMUs now in widespread use on regional services in southern and western Sweden.

Electrically, each train will be split into three units. Two will be formed with a driving motor, pantograph trailer and non-driving motor car, and the middle section will pair another non-driving motor and trailer car. This will give 20 powered axles out of 32 (Fig 1).

With a body width of 3 328 mm, the C2008 can easily accommodate the required 2+3 seating for standard class and 2+2 in first class, giving a total of up to 760 seats in an eight-car train (Table III). Seating will be a mix of face-to-face with tables and face-to-back airline style. Each vehicle will have a single wide doorway offset from the centre of the car, opening into a large vestibule area with toilets and related services. A bistro area will be included in each trainset.
