China has now owned the world’s longest high-speed rail network in the world, with about 9,300 km of route in service. The lines were mostly connecting the big cities all over the east side of the country. The CRH380A, which is develop in China with the highest speed up to 380km/h per hour, had been used in some of the lines such as Beijing–Shanghai and Beijing–Guangzhou–Shenzhen–Hong Kong. However, most of their line don’t have a very high passenger usage.
Why do you think there’s no much people using the Chinese HSR? Is it because of the high ticket price? Or because of any other reasons?
