China will again lay claim to operating 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 September 21 and additional lines will also be launched, according to the newspaper. China already has several of the world’s fastest operating trains. The fastest is a non-bullet train - the Shanghai Maglev - that can reach speeds up to 430 kilometers an hour. The train is limited to carrying passengers from Shanghai’s center to the city's airport.
