Shanghai–Zhengzhou high-speed train

The Shanghai–Zhengzhou high-speed train (沪郑高速动车组列车) are high-speed train services between Shanghai and Zhengzhou, the capital of Henan Province. Trains are operated by CR Shanghai and CR Zhengzhou.

History
The CRH services between Shanghai and Zhengzhou started on 10 September 2007, when the D-series trains commenced operations between the two cities on Beijing–Shanghai railway (later Beijing–Shanghai HSR) and Longhai railway.

The high-speed train services (G-series trains) between Shanghai and Zhengzhou was commenced on 10 September 2016, with the inauguration of the Zhengzhou–Xuzhou HSR (part of Xuzhou–Lanzhou HSR). On the same day, the D-series trains stopped services.

Operations
The G368/369 and G1814/1815 trains offer faster services with only two intermediate stops (Xuzhou East and Nanjing South) from Shanghai Hongqiao to Zhengzhou East, and are called as "benchmark trains". The travelling time of the trains is less than four hours (3h 57m-3h 59m). Other trains are services with more stops and longer travelling time.

According to the train numbering rules of China Railway, odd numbers are for south or west bound trains and even numbers are for north or east bound trains. The trains from Shanghai to Zhengzhou travel northbound on Beijing–Shanghai HSR and westbound on Xuzhou–Lanzhou HSR, and the trains from Zhengzhou to Shanghai travel eastbound on Xuzhou–Lanzhou HSR and southbound on Beijing–Shanghai HSR. Therefore, all the train services on this route have 2 train numbers for the same service.

Some CR Zhengzhou operated trains between Shanghai and Zhengzhou have their termini extended from Zhengzhou East to stations of some other cities in Henan, such as Jiaozuo (G1810/1811), Luoyang Longmen (G1812/1809 and G1822/1823), Anyang East (G1816/1813), and Xuchang East (G1808/1805).
