The yellow line is the mainland section while the green is built in Hong Kong.
The Shenzhen Futian Railway Station, said to be the largest underground railway station in Asia, is being put through operational tests and will open before the end of the year.
A high-speed train, with a maximum speed of 350 kilometers per hour, has been going between Shenzhen North Railway Station and Futian Railway Station.
Futian Railway Station, which cost about 3.95 billion yuan (US$622 million), is the first underground railway station in the central area of a city in China. It has three underground floors, providing train services to Beijing and Hong Kong and also links with Shenzhen’s Metro network, which includes Shekou Line, Longgang Line and the future Line 11. After the completion of the Guangzhou-Shenzhen-Hong Kong high-speed rail, it will take nine hours to travel from Beijing to Hong Kong and only 15 minutes from Shenzhen to Hong Kong.
And the first high-speed rail tunnel linking the Chinese mainland and Hong Kong has been cut through.
The 3,886-meter tunnel runs from Shenzhen City, south China's Guangdong Province to the Mai Po district of Hong Kong.
The Shenzhen section of the tunnel has been constructed to Chinese standards, with the section in Hong Kong built under European standards.
The project is part of the underground high-speed rail linking Shenzhen to Kowloon. Hong Kong will construct the Mai Po-Kowloon section. The Shenzhen-Kowloon high-speed rail will be connected to the already operating Beijing-Shenzhen rail line. The journey time from Beijing to Hong Kong will be cut from the current 20 hours to around nine hours.
