Posted by Anup Baral May 13th, 2In under a decade, China has built a high-speed rail network totalling more than 10,000km. It eclipses every other country’s high-speed network and even that of the entire European Union. Not only that, to build it China spent two-thirds or less what other countries have spent. According to a World Bank paper published last week, China’s high-speed rail so far has cost between $17m and $21m per kilometre, even though it has a high ratio of big-ticket viaducts and tunnels. In Europe that figure is $25m-$39m per kilometre, while in California, the only US state currently planning a high-speed line, it’s more like $56m/km.016
