随着最后一方混凝土浇筑完毕，郑州地铁6号线贾湿区间高架段圆满完成合龙。郑州地铁6号线从荥阳市贾峪镇站起至郑东新区小营站，全长39.13公里。这两天，郑州两条地铁线建设迎来关键节点。继9月8日3号线一期工程顺利试运行后，9月9日上午，4号线进入为期三年的试运行阶段。今年年底，这两条线路都将面向社会初期运营。

“科技蓝”与“盛世桔”，年底均将开启服务

每条地铁都有其独特的主色调：3号线以“盛世桔”为主色调，而4号线则以“科技蓝”为主题色。在试运行现场，从车身图案到车厢内饰、车站装修等，每处细节都通过多种设计手法打造特色。

以4号線為例，其車外觀以藍色為主調，並融入青铜鼎纹样元素，以此呼应商都历史文化。而在車站中，将不同文化融入設計，比如省体育中心站突出“活力郑州”，融入太极文化；金融岛北站突出“经济郑州”，呈现飞鸟造型；会展中心站突出“人文郑州”，充分融入汉字文化。

这几座特色鲜明的车站在展现城市的文化和风采，是城市最亮丽的公共空间。 Zhengzhou Subway Line 4, starting from the old hawk station in Huajiju District and ending at the river west road station in Guancheng District, is a south-north trunk line connecting the northern district, Zhengdong New Area, and southern district. The line runs along three full roads, national foundation roads, dragon lake middle circle roads, pleasant east roads, zhongzhou avenues, take-off roads, gold hills roads.

除了已进入试运行、即将于年底通车的3號線一期和4號線之外，《Zhengzhou City Rail Transit Third Phase Construction Plan (2019-2024)》中的项目也全面开工，其中包括3號線二期、6號線一期、7號線一期、8號線一期、10號線一期和12號線一期等。此前自2013年开始的地铁时代，现在正逐步成为现实，如今轨道交通计划达300公里以上，“Zhengzhou on Rails”正在由规划变为真实体验。

在地铁建设过程中，不断追求进步，并在服务品质上不断提升。例如，在4号线上应用了客流可视化导引系统以及智能服务机器人等新技术，大幅提高了设备可靠性及操作效率，并增加了能源控制措施。而在投用后的3 号 线，一端显示终端可以帮助乘客实时查看预计到达列车各个部分的人数分布情况，还增设了温奶器母婴室，更添了一份人性化待遇。

"Standing at the new starting point of Zhengzhou's national central city construction," said a senior official of Zhengzhou Metro Group Co., Ltd., "the initial operation of 3rd and 4th lines by year-end as well as already operational lines 1st to 5th will jointly support the network skeleton for urban districts. This marks that Zhengzhou Metro has officially entered into networked operations." With continuous improvement of metro network layout will effectively achieve cross-regional integration between north-south-east-west directions; form an urban development pattern connecting ecological residential areas in northern districts to financial business centers and science industrial parks; alleviate traffic congestion in cities; enhance public transportation service levels for residents etc., playing crucial roles.
