The first high-speed train sets off from the city of Guiyang on Friday Morning. It drives on the just finished Guiguang and Nanguang railways. China spent 125.9 billion yuan (20.28 billion U.S. dollars) and 6 years on the new high-speed railways, they will help 192 million people across three provinces.

The 856-km Guiguang high-speed railway can make the travel time between Guiyang and Guangzhou from 21 hours to 4 hours and 9 minutes. The 574-km Nanguang high-speed railway will make travel time between Nanning and Guangzhou from 13 hours to 3 hours and 19 minutes.

Li Shengming, a passenger of the train, is heading for Guangzhou for an eight-day trip. As a student at Guizhou University, Li always uses train when travelling between the two cities. "It took almost a whole day. It was really a hard trip," Li said. "With the high-speed train, however, the trip now only takes less than five hours.”

Passengers cheered when the train reached 250 kilometers per hour, its top speed. Madam Hu, 68, who is travelling with her friends, took a picture of the speed display with her cell phone. "This is a historic moment for the people of Guizhou. It's the first high-speed railway of Guizhou, my hometown. I have been looking forward to this moment," said Hu.
