China's fleet of high-speed trains is set once again to become the world's fastest. The top speed of the Fuxing or 'rejuvenation' bullet trains was capped at 300km/h (186mph) in 2011 following two crashes that killed 40 people. From next week, some of the trains will once again be allowed to run at a higher speed of about 350 km/h. The higher maximum speed should cut about an hour off the journey time between Beijing and Shanghai. By 21 September, seven of China's bullet trains will be permitted to travel at the increased maximum speed. To mark the return of the higher-speed service, the trains have been named 'Fuxing' - Chinese for rejuvenation - in line with a national government slogan and development plan.
The high-speed trains will be able to run at speeds of 350km/h following safety checks on rail lines.
