中国将再次运营全球最快的高速列车
中国将再次运营全球最快的高速列车

China will again operate the fastest bullet train service in the world. According to Chinese media, the Beijing to Shanghai train will once again be allowed to reach speeds up to 350 kilometers an hour. A deadly crash between two bullet trains in 2011 caused China to limit the speeds to 300 kilometers an hour.
The South China Morning Post reported the change will cut travel time by one hour on the 1,300 kilometer trip between Beijing and Shanghai. The faster Beijing-Shanghai trains will begin on September 21.
China already has several world's fastest operating trains. The fastest is a non-bullet train, the Shanghai Maglev that can reach speeds up to 430kilometers an hour. The train is limited to carrying passengers from Shanghai's center to the city's airport.
How fast are trains in other countries? The fastest non-operating train in the world— undergoing testing in Japan—has reached a top speed of 603 kilometers per hour. It is a Japan Railway maglev train. In Europe, Germany, Italy and Spain all have trains that can travel more than 320 kilometers an hour. In the United States, the Amtrak Acela Express, which connects several eastern cities, is the country's fastest train. It can travel at a top speed of 241 kilometers an hour.
