Early on, it was reported that the Zhengzhou-Wuhan section was to enter service on 1 July 2012; however, later on the date was moved back to the end of September 2012. Trial runs on this section began on 26 August. The line was put into service on 28 September 2012 between Zhengzhou and Wuhan, a distance of 536 km (333 mi).
As of its opening day, published schedules show a number of G-series trains running from the new Zhengzhou East railway station via Wuhan to Guangzhou. There are also some G-series trains from Wuhan to Zhengzhou railway station, where a convenient connection to the frequent service on the Zhengzhou–Xi'an high-speed railway is possible. A few direct trains from Xi'an North railway station to Guangzhou South and Shenzhen North (e.g. G824/G821 via Zhengzhou or G838/G835 via Zhengzhou East),
over the Zhengzhou–Xi'an high-speed railway and the Shijiazhiuang-Wuhan-Guangzhou line, have been introduced as well.
The entire Shijiazhuang–Wuhan line was put into service by the end of 2012.
