The Beijing–Zhengzhou high-speed train () are high-speed train services between Beijing and Zhengzhou, the capital of Henan Province. Most of the trains are operated by CR Zhengzhou while some are operated by CR Beijing and CR Nanchang. History The express train services between Beijing and Zhengzhou used to be the T-series train with train number T57/58 prior to the CRH era. The service was operated between and on the Beijing–Guangzhou railway, with a travelling time of 6h 42m. In 2007, the T57/58 service was cancelled with the introduction of the D-series trains on the Beijing–Guangzhou railway on 18 April. The D-series trains, operated with CRH2A (was later replaced by CRH5A) EMUs, shortened the travelling time to 4h 47m. With the completion of the Beijing–Zhengzhou section of the Beijing–Guangzhou–Shenzhen–Hong Kong HSR, the D-series trains on the conventional railway stopped services on 21 December 2012 and was replaced by the faster G-series trains on the new high-speed railway, which was opened 5 days later, on 26 December 2012. At initial stage, 4 pairs of G-series trains were operated daily between Beijing West and Zhengzhou East with train numbers G89/90 and G561-566, and 1 pair of D-series train with train numbers D2021/2022. On 28 December 2013, the timetables of the services were adjusted and a new pair of G-series trains (G559/560) between Beijing West and Zhengzhou East were added. There were some major adjustments to the services on 1 July 2014. The only D-series train D2021/2022 was promoted to G-series with train number G563/560. Some trains had their train numbers changed: the former G560 was changed to G562, the former G562 ( → Beijing West) was changed to G564, the former G564 was changed to G566, the former G565 was extended from Zhengzhou East to Zhengzhou and was changed to G567, the former G567 was changed to G569, and the former G568 was changed to G570. The service between Beijing West and also had the train numbers changed: the former G569/570 was changed to G429/430. This pair of train was later extended to Zhengzhou East on 10 January 2016. After the opening of the Zhengzhou–Xuzhou high-speed railway, the G89/90 service was extended from Zhengzhou East to Zhengzhou, and the G559/560 was extended to on 10 November 2016, and was re-numbered as G1559/1562 and G1561/1560. On 16 April 2017, the G89/G90, G566 and G569/570 had their train numbers changed to G805/802, G806 and G807/808
