The Wuhan–Guangzhou high-speed railway, also called the Wuguang high-speed railway and short for Beijing–Guangzhou–Shenzhen–Hong Kong high-speed railway, Wuhan–Guangzhou section, is a 968-kilometre (601 mi) high-speed rail line, operated by China Railway High-speed (CRH), connecting Wuhan and Guangzhou, the provincial capitals of Hubei and Guangdong, respectively. It was the world's fastest train service, initially using coupled CRH2C and CRH3C trains which averages 313 km/h (194 mph) in non-stop commercial service.

The Beijing–Guangzhou–Shenzhen–Hong Kong high-speed railway or Jingguangshengang high-speed railway from its Chinese name is a high-speed railway corridor of the CRH passenger service, connecting Beijingxi station in Beijing and Futian station in Shenzhen, Guangdong in less than nine hours of travel time. It is 2,230 kilometres (1,390 mi) long, and is the only Chinese high-speed railway to cross a border that requires immigration and customs clearance. The existing, conventional Jingguang railway runs largely parallel to the line.
