BEIJING - China's high-speed train lines now exceed 10,000 kilometers after a railway track linking the coastal city of Fuzhou and in-land Nanchang began operating on Thursday morning.

It is the fourth line to open this year and the total length of track for speedy trains in the country is 10,463 kilometers. Last year, the figure was 9,356 kilometers.
