Congratulations to the team on a great success.<p>I live in China and hi-speed intercity travel here is both affordable and fast. CRH is building up at China speeds, with new stations popping up almost weekly. It used to run at 370-380 kph (240 mph), but after the Wenzhou train accident, all CRH trains were capped at 300 kph, even if the trains are being developed here that can go 500+ mph.<p>However, behind the affordable practicality of CRH, we often forget how expensive and disturbing the whole network is. It's obviously not turning a profit when we can get from Shanghai to Nanjing in 1 hour and 124 RMB ($18). And it's very noisy as well, standing inside the small stations when non-stop trains pass by (or should we say "zap by") the deafening roar of the train going even at 300 kph will shock you. And around Shanghai, those trains pass by every 5 minutes or so, producing a lot of noise. And this being China, urban never ends, one city flows into another, and a lot of people live nearby CRH lines.<p>Though China is already a very noisy environment, I would welcome "upgrading" those CRH lines to Hyperloops eventually. Most of them are elevated, and with China's massive capital they must already think about how to cut those short travel times between economic hubs even shorter.
