China to open world’s longest high-speed rail line

China will open the world’s longest high-speed rail line next week when a link between Beijing and the southern metropolis of Guangzhou is inaugurated, officials said on Saturday. The 2,298-km (1,428-mile) line, parts of which are already in operation, will begin full service on Wednesday, halving travel time to less than 10 hours on trains which will run at 300 kph (186 mph).
