Hangzhou–Fuzhou–Shenzhen High Speed Railway

The Hangzhou–Fuzhou–Shenzhen High-Speed Railway (杭福深高速铁路 formerly 东南沿海快速通道 or 东南沿海铁路) refers to the dual-track, electrified, high-speed rail lines (HSR) in service along the southeastern coast of China, which links the Yangtze River Delta on the East China Sea and Pearl River Delta on the South China Sea. It is one of the eight arterial high-speed rail corridors that form the backbone of China's HSR network. The southeast coast is the only region of high-speed rail construction where no previous conventional railroads existed. Hence, the high-speed rail lines built on the southeast coast will, for the most part, carry both passenger and freight traffic, and will not be passenger-dedicated lines that comprise most of the other HSR corridors in China.

An additional bridge will be built across Hangzhou Bay for high-speed rail, providing a direct link between Shanghai and Ningbo before 2020. The Southeast Coast HSR Corridor is approximately 1,745 km (1,084 mi) in length, and crosses three coastal provinces, Zhejiang, Fujian and Guangdong. Major cities along the route include Hangzhou, Ningbo, Taizhou, Wenzhou, Fuzhou, Quanzhou, Xiamen, Zhangzhou, Chaozhou, Shantou, Shanwei, Huizhou and Shenzhen.
