Researchers in Shanghai have developed China-patented metro trains which will probably see commercial use beginning in 2006, according to Tongji University.
Since last September, Tongji's rail transportation research center has been cooperating with the Shanghai Electric Group on a train development program. Progress is reported to be smooth.
The China-patented technology, which is more adapted to the country's conditions, is expected to reduce the production costs of the trains, researchers said.  Trains currently running on China's rail lines are imported or domestically produced products based on foreign technologies.
