New high-speed train set for trial run

China Daily (Canada) - - CHINA - By ZHAO LEI zhaolei@chi­nadaily.com.cn

A trial run of China’s new high-speed bul­let train, which uses a cut­ting-edge trac­tion sys­tem, will start soon, ac­cord­ing to the head of the high­speed rail­way in­no­va­tion pro­gram.

The per­ma­nent­mag­net syn­chro­nous trac­tion sys­tem was de­vel­oped by CSR Corp Ltd, one of the coun­try’s two ma­jor lo­co­mo­tive mak­ers, at its Zhuzhou In­sti­tute in Hu­nan prov­ince. It has passed pre­lim­i­nary ex­am­i­na­tion by na­tional rail­way test au­thor­i­ties and has been in­stalled on a new bul­let train pro­duced by CSR Qing­dao Si­fang Co Ltd in Shan­dong prov­ince, said Jia Limin, a pro­fes­sor at Beijing Jiao­tong Univer­sity who heads China’s high-speed rail­way in­no­va­tion pro­gram.

“If ev­ery­thing goes well, we will be­gin a trial run in a short time and then im­prove the equip­ment based on the tests,” he said. “I think the new train will be­come fully op­er­a­tional by 2018.”

Com­pared with the al­ter­nat­ing cur­rent asyn­chro­nous mo­tors that are com­monly used for a bul­let train’s trac­tion sys­tem, the per­ma­nent mag­net syn­chro­nous trac­tion boasts high power, a sim­ple con­fig­u­ra­tion and low fuel con­sump­tion, Jia said.

He added: “The new sys­tem has fewer parts than the cur­rent trac­tion ap­pa­ra­tus, so it is more re­li­able and ef­fi­cient. Other ad­van­tages in­clude oc­cu­py­ing a smaller space on the train and pro­duc­ing less noise dur­ing op­er­a­tion.”

Xu Jun­feng, who over­saw the trac­tion sys­tem’s de­vel­op­ment, said: “Cur­rently, six out of eight cars of a bul­let train need to have en­gines. Us­ing the new trac­tion sys­tem will al­low only four cars to be fit­ted with en­gines, which will sub­stan­tially re­duce costs and main­te­nance pro­ce­dures.”

The CSR Zhuzhou In­sti­tute launched the project in 2011 and has been in charge of all core tech­nolo­gies for per­ma­nent mag­net trac­tion, which will be the main­stream of trac­tion de­vices for next-gen­er­a­tion bul­let trains, Xu said.

Na­tions with strong tech­no­log­i­cal ca­pa­bil­ity in high­speed rail­ways, such as Ger­many and Ja­pan, be­gan re­search­ing per­ma­nent mag­net syn­chro­nous trac­tion about eight years ago. China is still at the ini­tial stage but has made big strides, Jia said.

Ear­lier re­ports said a sub­way train in Shenyang, cap­i­tal of Liaon­ing prov­ince, was fit­ted with the per­ma­nent mag­net syn­chro­nous trac­tion sys­tem to test its re­li­a­bil­ity.

China has been striv­ing to de­velop and man­u­fac­ture all ma­jor com­po­nents used on its high-speed bul­let trains.

Sheng Guangzu, the gen­eral man­ager of China Rail­way Corp, has pledged to speed up thede­vel­op­mentofkey tech­nolo­gies used in high-speed trains and to de­sign a new­bul­let train with “Chi­nese stan­dards”.

“In the high-speed train field, we must ac­cel­er­ate the re­search of cru­cial tech­nolo­gies. We will strive to com­plete the de­sign of theChi­nese-stan­dard bul­let train and its ma­jor com­po­nents by the end of the year,” Sheng said in Jan­uary.

Most of the ad­vanced com­po­nents used on China’s bul­let trains, such as trac­tion, brake and con­trol soft­ware, are pro­vided by for­eign com­pa­nies in­clud­ing Al­stom, Siemens and Kawasaki Heavy In­dus­tries, ac­cord­ing to sources close to China Rail­way Corp.
