The line runs entirely underground, has 20 stations and is served by a fleet of six-car Type B metro vehicles supplied by CSR Zhuzhou. Line 1 is expected to carry a peak of 100,000 passengers per day during holidays.

This is the first metro line in the world to utilise 4G Long Term Evolution (LTE) technology. Initially the network is using the platform for CCTV and passenger information services, but the system's supplier Huawei says tests are underway to host the network's CBTC signalling system with a view to adopting it by the end of the year.

Zhengzhou Metro Company plans to invest Yuan 10.2bn ($US 1.68bn) in its metro network development plan, with construction of the initial 19km, 16-station section of the north-south Line 2, 17.25km of which is underground, underway and expected to open in 2015. Construction of the 40.8km east-west Line 3 is set to commence later this year and be completed by 2018, while work on the 35.3km Z-shaped Line 4 will start in 2015 and open in 2020, and Line 5, a 41.8km ring line, which has received funding from the World Bank, will be completed in 2016.

The February 2014 edition of International Railway Journal will feature an in-depth report on Zhengzhou metro's LTE project.
