World’s fastest high-speed train blazes to 453 km/h in pre-service trials - Global Times
“The world’s fastest bullet train, the CR450, has begun a battery of pre-service trials on a high-speed line in China, clocking a single-train speed of 453 kilometers per hour [280 mph].
The CR450 series, engineered for a top test speed of 450 km/h and a commercial service speed of 400 km/h, is now undergoing qualification trials on the high-speed rail linking the eastern city of Shanghai and a western inland one of Chengdu, Science and Technology Daily reported on Monday. …
… The CR450 will log 600,000 trouble-free kilometers before it is cleared to carry passengers.”
The train is being tested on a line which is over 1,000 miles long. At those speeds, it is getting within shouting distance of being competitive with aircraft. Remember the days when big news like this came from the US? Was not that long ago.
