"There will be trains every several minutes. Buying a ticket, getting through the checkpoint and taking your seat, will take just 10 minutes," said an engineer. There may be high-speed trains running at 350 kilometers an hour. The travel time between the two cities will _ from 10 to about 5 hours. The trains will carry twice the present number of passengers. The new line will be 1,318 kilometers long and go across specially built bridges. It will run along side the present line. There will be 21 stations in Hebei, Tianjin, Shandong, Anhui and Jiangsu.
