Ahead of Beijing Winter Olympics and Paralympic games, China has launched world&rsquos first driverless bullet train, which will reduce the travel time more than half. The train, at top speed, can go about 350km/hr. Zhangjiakou, where most of the skiing events will take place, currently takes about 3 hours to commute. With the bullet train in operation, the travel time will be reduced to a little less than hour, which is a considerable reduction from the eight hours it took in 1909, when the original line was established.
