Ten new railways with an aggregate operating mileage of 2,500 km will be put into service by the end of this year to enhance the capability of China's high-speed rails, sources from the China Railway said. About 553 new high-speed train services will be introduced simultaneously, which is expected to elevate China's high-speed rail transport capacity by 9 percent, according to the sources. The change will also make high-speed railway services available for the first time in a dozen cities, including Fuxin and Chaoyang in Liaoning province, Chengde in Hebei, Tongliao in Inner Mongolia, Mudanjiang in Heilongjiang, Rizhao in Shandong, Lianyungang and Yancheng in Jiangsu, Yaan in Sichuan and Lijiang in Yunnan.
