In 2015, China invested 823.8 billion yuan (about $127 billion) on railways. Investment was made in 9,531 km of new lines, of which 3,306 km were high-speed rail.
By the end of 2015, the network length in China reached 121,000 km and the length of high-speed rail in operation was over 19,000 km, accounting for 60 per cent of the world's total.
Chinese Vice-Premier Ma Kai recently emphasised that as this year is the first year of the 13th Five-Years Plan, related departments must work hard to guarantee the completion of 800 billion yuan of investment in railway.
