TOKYO -- When China recently reclaimed the title of having the world fastest train, it might have been a moment of national celebration. Instead, there were worries about whether the cost was worth it.
The "Fuxing" (rejuvenation) high-speed train service between Beijing and Shanghai returned to operating at 350kph on Sept. 21. For six years, it had been limited to 300kph following a crash in 2011 when two high-speed trains collided, killing 40 people and injuring about 200.
