The construction of high-speed railways in China began with the building of the Qinhuangdao–Shenyang High-Speed Railway in 1999. Now the high-speed rail network in China is the largest in the world. As of the end of 2012, there are about 17,000 kilometers of high-speed rail in service, accommodating trains of an average speed of 200 km/h or higher.
China’s high-speed rail plans are ambitious, planning to invest $300 billion to construct the largest, fastest, and most technologically advanced high-speed railway system in the world by 2020. It is predicted that the HSR (High-Speed Railway) network will reach 30,000 kilometers when the major rail lines are completed. China’s high-speed railway network is made up of four components: upgraded pre-existing rail lines that can accommodate high-speed trains, a national grid of mostly passenger dedicated HSR lines (PDLs), certain regional intercity HSR lines, and the Maglev High-Speed Line.
