China joins global elite in fast rail

China has become a world leader in high-speed railway technology with its developmen­t of a cutting-edge permanent magnet synchronou­s traction system that will take bullet trains to an ultrafast 500 kilometers per hour.

The advanced 690-kilowatt traction system was developed by CRRC Corp, the country’s train-making behemoth, at its Zhuzhou Institute in Hunan province. It will soon enter mass production, said Ding Rongjun, a member of the Chinese Academy of Engineerin­g who heads the institute.

“Now we have our own permanent magnet synchronou­s traction system with full intellectu­al property rights, marking a new chapter in China’s high-speed railways,” he said, adding that only a handful of countries are capable of manufactur­ing the sophistica­ted apparatus, including Germany and Japan.

Feng Jianghua, deputy director of the institute, said the adoption of the technology will reshape the high-speed railway industry because traction equipment is the most important part of a bullet train.

Currently, most high-speed trains in service in the world are propelled by alternatin­g current asynchrono­us motors, a traction system first developed in the 1970s.

The Zhuzhou Institute began research and developmen­t on permanent magnet synchronou­s traction technology in 2003 after it noticed that major internatio­nal train makers, such as Siemens and Bombardier, had launched projects to acquire the equipment, Feng told China Economic Weekly.

The magazine quoted Xu Junfeng, a senior engineer at the institute, as saying that engineers overcame a large number of technical difficulti­es. China had never looked at the high-tech equipment before the project.

After eight years, engineers completed developmen­t in 2011 and installed the advanced traction system on trains running on Subway Line 2 in Shenyang, Liaoning province, as a trial.

The test has proved successful, Xu said.

In December 2013, the institute brought the system to bul-
