Route

The 10.8 km long tunnel is part of a 140-kilometer (87 mi)-long high-speed line from Guangzhou to Shenzhen and Hong Kong. It is designed for speeds of up to 350 km/h (usually 250 km/h in operation) - the fastest underwater tunnel in the world. [2] as well as being China's longest underwater tunnel. [3] This allows rail journeys between Guangzhou and Hong Kong to take only 40 minutes – much faster than the previous 2-hour journey. The Guangzhou-Shenzhen-Hong Kong express rail link is part of a broader expansion of high-speed rail in China; journeys from Beijing to Hong Kong will take only 8 hours. [4]

Construction

Construction began in November 2007, with a budget of CNY2.4 billion; [5] the tunnel was completed in 2011, and passenger services began on 26 December 2011. [4] Unusually, the tunnel boring machines were designed to be dismantled inside the tunnel. [5]

Pearl River Major river in southern China

The Pearl River, also known by its Chinese name Zhujiang or Zhu Jiang in Mandarin pinyin or Chu Kiang and formerly often known as the Canton River, is an extensive river system in southern China. The name "Pearl River" is also often used as a catch-all for the watersheds of the Xi ("West"), Bei ("North"), and Dong ("East") rivers of Guangdong. These rivers are all considered tributaries of the Pearl River because they share a common delta, the Pearl River Delta. Measured from the farthest reaches of the Xi River, the 2,400-kilometer (1,500 mi)-long Pearl River system is China's third-longest river, after the Yangtze River and the Yellow River, and second largest by volume, after the Yangtze. The 453,700 km2 (175,200 sq mi) Pearl River Basin (珠江流域) drains the majority of Liangguang, as well as parts of Yunnan, Guizhou, Hunan and Jiangxi in China; it also drains northern parts of Vietnam's Northeast Cao Bằng and Lạng Sơn provinces.
