开路先锋，踔厉奋发向未来

交通強国，铁路先行。

铁路是国家重大基础设施，是国民经济大动脉。70年来，中铁二院参与建成的国内铁路通车里程超过36000km，占全国铁路总里程1/4，其中高速铁路超过12000km，占全国高铁总里程1/3。

70载光阴，地处中国西南的“铁二院”已成长为交通领域的领军企业。这是三代二院人笃行不怠、踔厉奋发的丰硕成果。

这70年，是步履不停的征程。从勘察设计到工程总承包，从规划咨询到产品产业化，涉及领域不断延伸；铁路公路、市政城轨、港口码头、民航机场……一张以勘察设计为支点的密网正在快速织就。

这70年，是勇攀高峰的拼搏。从成渝到宝成，从成昆到南昆，再到雪域高原上的拉林铁路……一个个“第一”不负韶华；郑西、贵广、西成、郑渝等多条高速铁路干线，见证着二院人接续奋斗的历程。

这70年，是敢于创新的气魄。复杂艰险山区高原铁路建设、高地温深埋特长隧道修建、大断面黄土隧道修建等，二院人用智慧与汗水攻下了一个个技术高峰，先后荣获国家科技进步奖30余项，编制了168项国家及行业标准、2项国际标准，获得国家授权专利近2200项。

从西南到全国，再到海外，征途漫漫。从“走出去”到共建“一带一路”，以东非高原的坦赞铁路为起点，中铁二院的全球坐标已然建立。

在埃塞、老挝、埃及等全球70多个国家和地区，一个个“一带一路”典范工程接连筑就：亚吉铁路、中老铁路、埃及斋月十日城轻轨……作为“走出去”的先行者和引领者，中铁二院将“中国设计”“中国标准”扎根海外，中国基建“走出去”的步伐愈加稳健。

面向未来，中铁二院人将始终如一，做新时代的“开路先锋”，创“交通强国”更大的辉煌。

Railways should serve as the trailblazer to grow China into a country with a strong transportation network.

Railway is a nation’s important infrastructure and also the big artery of national economy. For seven decades， the railways in China open to traffic constructed by China Railway Eryuan Engineering Group Co.， Ltd. （CREEC） have been over 36，000 kilometers long， and the length accounts for 1/4 of the total length of railways in the country. Of them， the high-speed railways are over 12，000 kilometers long， and the length takes up 1/3 of the total length of high-speed railways in China.

After seven decades， CREEC， formerly known as Second Survey and Design Institute of China Railway based in Southwest China， has grown into a leading enterprise in the transportation sector， as a result of its three generations of staff’s unremitting efforts.

The past 70 years were a journey with non-stop developments. From survey and design to EPC， from planning and consultation to product industrialization — CREEC has been expanding its business. It rapidly wove a network， which is based on survey and design and covers railways and highways， municipal works and urban rail transit， ports and wharves， and civil aviation airports.

The past 70 years were a journey with striving for greater achievements. From Chengdu-Chongqing Railway to Baoji-Chengdu Railway， from Chengdu-Kunming Railway to Nanning-Kunming Railway and Lhasa-Nyingchi Railway on the snow-covered plateau — CREEC achieved many firsts during this period. Many high-speed railway trunk lines， including Zhengzhou-Xi’an High-speed Railway， Guiyang-Guangzhou High-speed Railway， Xi’an-Chengdu High-Speed Railway， and Zhengzhou-Chongqing High-speed Railway， witnessed the continuous struggle of the staff of CREEC.

The past 70 years were a journey with courage for innovation. The staff of CREEC addressed one after another technical challenge with wisdom and sweat： They built railways in mountainous areas and on plateaus with complex and dangerous geological conditions， deep-buried extra-long tunnels with high ground temperature， and large-section loess tunnels. CREEC won 30-plus State Scientific and Technological Progress Awards， compiled 168 national and industrial standards， 2 international standards， and obtained nearly 2，200 national authorized patents.

CREEC trudged over a long journey to develop from Southwest China to the rest of the country and then to other parts of the world. From “going global” to the Belt and Road Initiative （BRI）， CREEC responded to national strategies. Starting with the Tanzania-Zambia Railway in East Africa， CREEC began its development in the global arena.

BRI model projects constructed by CREEC， including the Addis Ababa-Djibouti Railway， the China-Laos Railway， and the 10th of Ramadan Light Rail Transit in Egypt， sprung up in over 70 countries and regions， such as Ethiopia， Laos， and Egypt. As a pioneer and leader of “going global”， CREEC brought “China’s design” and “China’s standards” to foreign countries， allowing China’s infrastructure to have more steady development abroad.

Looking into the future， the staff of CREEC will still be the pioneer in the new era， contributing more to growing China into a country with a strong transportation network.
