I'm a French guy living in China. Reading that China has the "most advanced [...] high-speed rail lines in the world" makes me jump on my chair. The HSR trains are rarely going to the announced 240 km/h top speed, most of the time, they aren't even reaching 200. China is just building it's first Shanghai to Beijing in 3:30 thanks to the French technology (to be ready later this year). It still takes 40 hours to travel from Shanghai to Wulumuqi. Exactly where is the advance here? The most advanced country in the world for train is France, with over 6 lines at 320+ km/h all over the (small) country and extending to the rest of Europe (Spain, London, Amsterdam)!
