For context, the total length of high speed rail in the world is 59,000km. So China, which makes up 17% of the world’s population contains 2/3 of the world’s high speed rail.
The closest comparison would be Europe, which has about the same land mass and half the population of China has around 11,000km of big speed rail.
I wonder what proportion of it is also due to people fleeing 1 million + average house markets during the pandemic work from home wave. Not saying this about you, but it makes me think it’s funny how the common refrain of “Don’t like it? Just move” is often uttered by NIMBYs.
