Zhengzhou–Shenzhen high-speed train

The Zhengzhou–Shenzhen high-speed train (郑深高速动车组列车) are high-speed train services between Zhengzhou, the capital city of Henan Province, and Shenzhen, a major city in Guangdong Province.

History
The service commenced operations on 28 September 2012, when the Zhengzhou–Wuhan section of the Beijing–Guangzhou–Shenzhen–Hong Kong HSR was put into operation.

Operations
The services are operated on the Beijing–Guangzhou–Shenzhen–Hong Kong HSR and Zhengzhou–Jiaozuo ICR (G75 only).
