The line is one of the segments of the Xuzhou–Lanzhou high-speed railway, a high-speed mainline from Lanzhou to Xuzhou, paralleling the existing Longhai Railway line.

The densely populated corridor between Zhengzhou and Xi'an, both large regional centres, is home to some 100 million people. Its top speed is 350 km/h (220 mph) in operation and the minimum travel time between the two cities is 1 hour and 58 minutes, although in practice, the journey takes more than two hours with a few intermediate stops.[1]

When the high-speed line first opened, the trains departed and arrived at the "old" main train stations of Zhengzhou and Xi'an. Once the new Xi'an North railway station was opened, all high-speed service in Xi'an was routed to it. In Zhengzhou, now both the Zhengzhou Railway Station and the new Zhengzhou East railway station are served by high-speed trains from Xi'an.

The faster, G-series trains on the Zhengzhou–Xi'an Railway are numbered G20xx. Westbound trains (Zhengzhou to Xi'an) are odd-numbered, while even numbers denote eastbound trains (Xi'an to Zhengzhou).

With the opening of the Zhengzhou–Wuhan section of the Beijing–Guangzhou high-speed railway in the fall of 2012, direct high-speed service from Xi'an to Wuhan, Changsha, Guangzhou, and Shenzhen was introduced.[2] As well, after the Beijing-Shijiazhuang-Zhengzhou section of the Beijing–Guangzhou line became operational at the end of 2012, direct Xi'an-Beijing service became available.

The railway has made air service between Zhengzhou and Xi'an uncompetitive. All passenger flights between the two cities were suspended within 48 days of the start of regular high-speed rail service.[3]
