Movia cars arrive in Guangzhou

01 Jan 2003

The first of 154 Movia metro vehicles being built for Guangzhou Line 2 were flown to China in November

DECEMBER 29 is due to see the formal 'first trip' on Guangzhou metro Line 2. The 23 km route from Jiangxia to Bazhou is now expected to open for revenue service in April 2003, almost a year ahead of schedule. The line will be worked by a fleet of 26 six-car Movia modular trainsets, which were ordered from the Changchun Bombardier Railway Vehicles joint venture in August 2000 at a cost of 1·5bn yuan.

The first two sets are being built at Hennigsdorf near Berlin, which supplied the 21 first-generation trains for Guangzhou Line 1. The remaining 24 sets will be assembled in Changchun. The vehicles are constructed using Bombardier's 'flat-pack' technique, where the roof, floor and sidewall assemblies are completed before being joined to form the main structure. Bogies are supplied from Bombardier's Derby plant in the UK, and the traction equipment from Västerås in Sweden.

The initial German-built vehicles were rolled out in Berlin during November, and flown to China as planned to meet the delivery schedule. On November 26 the first two cars were moved by low-loader from the Bombardier plant at Hennigsdorf to the airfield at Parchim in Mecklenburg-Vorpommern, to be loaded on board an Antonov AN124 heavy-lift transporter.

After 12h the load was secure and the plane was off. Three refuelling stops and 36 h later, the flight was welcomed on arrival in Guangzhou by Deputy Mayor Li Zhoubin. Rauno Boga, Vice-President,Sales, of Bombardier Metros officially presented the vehicles to the representatives from the city.

Two further flights took place during December to deliver the remaining four cars of the initial trainset, ready for the launch run at the end of the year.

High capacity

Each trainset is formed from two matching half-sets, comprising a 24m driving trailer, 23m motor car with pantograph and another intermediate motor car. The 3·1m wide cars are connected by 1·5m gangways, making it easy to move along the entire train. Each vehicle can accommodate 56 seated passengers and 310 standees at 6 per m2. Crushload for a six-car train has been calculated as 2592 passengers at 9 per m2.

The vehicle bodyshells are made from welded aluminium profiles, having aluminium intermediate ends covered with a composite moulding. The cab ends have a steel structure supporting a composite cover. Each vehicle has five 1·4m wide doorways, with external sliding doors. The cabs are accessed by a single-leaf door sliding into a recessed pocket.

The 2·5m wheelbase H-framed bogies have conical rubber primary springs and secondary air suspension. All axles on the four motor cars are powered, with resiliently-mounted 220 kW three-phase motors driving through single-stage gearboxes. The maximum speed in service is 80 km/h. Both rheostatic and tread brakes are fitted. Wheel diameter can vary from 840mm new to 770mm worn. Floor height is 1·13m above rail, giving level boarding from the station platforms.

Although a driver will be carried, the trains are designed to run in ATO mode, in common with the Line 1 fleet. The 1·5 kV DC overhead supply is taken to four Mitrac
