China is negotiating to extend its own high·-speed railway network to up to 17 countries in 1 0 to 15 years，eventually reaching London and Singapore．

　　China has proposed three such projects．The first would possibly connect Kunming with

　　Singapore via Vietnam and Malaysia．Another could start in Urumqi and go through Kazakhstan and Uzbekistan，and possibly to Germany．The third would start in the northeast and go north through Russia and then into Western Europe．

　　If China’s plan for the high-speed railway goes forward，people could zip over from London to Beiling in under two days．

　　The new system would still follow China’s high—speed railway standard．And the trains would be able to go 346 kilometers an hour，almost as fast as some airplanes．

　　China’s bullet train(高速客车)，the one connecting Wuhan to Guangzhou，already has the

　　World’s fastest average speed．It covers 1,069 kilometers in about three hours．

　　Of course，there are some technical challenges to overcome．There are so many issues that need to be settled，such as safety，rail gauge(轨距)，maintenance of railway tracks．So，it’s important to pay attention to every detail．

　　But the key issue is really money．China is already spending hundreds of billions of yuan on

　　domestic railway expansion．
