China’s high-speed railway (HSR) is the most recent poster child for the country’s rapid development, with more HSR tracks than the rest of the world combined. Since 2004, the Chinese government has invested more than 10 trillion RMB to build a 40,000-kilometer (km) network of trains that zip between stations at speeds reaching 350 km/hr (or 220 miles per hour). Not to be outdone, by 2035 the government aims to expand this train network by 75 percent to help the country reach its transport connectivity and low-carbon transportation goals.
