Zhengzhou Metro Line 4 starts from Laoyachen Station of Huiji District and ends at Langzhuang Station of Guancheng District, covering a total length of 29.217km, featuring 27 stations including 10 interchange stations. The operating hours after the launch of the service are from 6:00 to 23:00, which takes about 54 minutes for a single journey. Upon the opening of Line 4, which joins the underground arteries between the north and the south, it further perfects the network of metro lines in the downtown area and facilitates the citizens' travelling along the line, turning the "Zhengzhou on the rail" into reality step by step.

The dynamic map supplied by HUAQI perfectly corresponds to the theme of technology blue. The new reminder functions of current carriage location and estimated arrival time at each station ahead have been introduced to be more user-friendly and convenient for traveling passengers.

Henan HUAQI

Following Zhengzhou Metro Line 5, Metro Line 14 and Zhengzhou Suburban Line, Zhengzhou Metro Line 4, which was launched this time, is the fourth line that HUAQI serves for Zhengzhou. Being the center of China and the thoroughfare of ten provinces, the geographical advantage of Zhengzhou is very evident. For the purpose of better serving the rail transit city construction of Zhengzhou and well supporting Zhengzhou CRRC rail transit project, as early as the early 2017, upon the start of Xingyang Rail Transit Equipment Manufacturing Industrial Zone CRRC Hi-Tech Park, HUAQI established Henan HUAQI Sichuang Intelligent Technology Co., Ltd. (hereinafter referred to as “Henan HUAQI”). As such, Henan HUAQI stands for the earliest representative of the system provider who has invested, implemented production and carried out localization in CRRC Hi-Tech Park, being the benchmark enterprise in the park.

Ever since its settlement in Zhengzhou in 2017, Henan HUAQI has been involved in almost all the newly commenced projects in Zhengzhou, delivering products and services for more than 600 metro vehicles in Zhengzhou. Since its foundation in 2017, through 4 years of development, the Company has acquired ISO/TS22163, ISO9001, IATF16949 and other system certifications, been honored as a software enterprise in Henan Province, a high-tech enterprise of Zhengzhou, an intelligent manufacturing demonstration enterprise of Zhengzhou, and a specialized and innovative enterprise of Xingyang. Henan HUAQI has established a dual business model focusing on rail transit + urban bus (bus + intelligent bus station), which has laid a favorable foundation for the stable and long-term development of the Company.

In the future, Henan HUAQI will be closely in pace with the construction of Zhengzhou national central city, being grounded in Zhengzhou, radiating the entire Central Plains region, and gradually developing into a high-tech enterprise integrating product development, system integration, operation service and technical consulting in the rail transit industry. Efforts will be directed to integrate the geographical advantages with the strengths of HUAQI to deliver timely, attentive and top-quality services to customers. Henan HUAQI will jointly work with the citizens of Zhengzhou to construct and witness the emergence of the "Zhengzhou on the rail"!
