The high-speed railway handled 8.51 million passengers per day on average during the holiday, up 11.9 percent year-on-year, data from China State Railway Group Co Ltd shows.

The length of China's high-speed rail lines has surpassed 30,000 km, ranking first in the world.

High-speed rail has sped up the process of China's urbanization and industrialization, and will help form an economic belt along the high-speed railway, Ding Ningning, a researcher with the Development Research Center of the State Council, said in a previous interview.
