China completed on Saturday the construction of its first underwater railway tunnel that enables trains to run at the fastest speed in the world under the water, Xinhua reported.
The project, called the Shiziyang Tunnel, crossed the Pearl River estuary in south China's Guangdong Province with a length of 10.8 kilometers. It is designed for trains travelling at 350 kilometers per hour.
The 10.8-kilometer tunnel is a key part of a 140-kilometer rail link that connects Guangzhou, the capital of China's southern economic powerhouse Guangdong, with the city of Shenzhen, also in Guangdong, and Hong Kong.
The service is also expected to join with the country's express railway network and take passengers only eight hours from Hong Kong to Beijing.
