The Beijing–Hong Kong high-speed train (simplified Chinese: 京港高速动车组列车; traditional Chinese: 京港高速動車組列車) is a high-speed train service operated by China Railway Guangzhou Group (CR Guangzhou) on Beijing–Guangzhou–Shenzhen–Hong Kong HSR in China.

[1][2] The G79/80 service dates back to 26 December 2012, when the Beijing–Zhengzhou section of the Beijing–Guangzhou–Shenzhen–Hong Kong HSR was opened.

At its opening, the service was between Beijing West and Guangzhou South under the numbers G79/82.

However, from 15 June 2024, they were again replaced by the double-headed CR400AF-Z(Base in Shenzhen Depot) to enable quiet cars on this route.
