中铁二院
——轨道交通“魔法师”

3月31日，由中铁二院工程集团有限责任公司（以下简称“中铁二院”）全程参与设计、施工配合、施工监理、车辆监造，历经5年规划建设的云南省文山壮族苗族自治州城市轨道交通现代有轨电车4号线开通试运行，该项目是云南省第一条正式开通试运行的有轨电车项目，也是国内首批采用PPP模式建造、国内首个在革命老区和边疆少数民族地区建设的有轨电车项目，拥有多个全国首创，是中铁二院在新制式轨道交通领域的又一力作。

当下，新型多制式轨道交通正成为中国城轨建设“新宠”，中铁二院响应国家“交通强国”“创新驱动发展”的号召，开发运用中低速磁浮，跨座式单轨，现代有轨电车等技术，成为新制式轨道交通领域的主要探路者和重要实践者。

After five years of planning and construction, the modern tram line 4 project of Wenshan Zhuang and Miao Autonomous Prefecture in Yunnan Province was put into trial operation on March 31.China Railway Eryuan Engineering Group Co., Ltd.（hereinafter referred to as “CREEC”） participated in the whole process of design, construction coordination, construction supervision, and vehicle supervision for the project.This project is the first tram project officially put into trial operation in Yunnan Province, and also the first tram project adopting PPP mode in China and the first tram project built in an old revolutionary base area and frontier ethnic region in China.It is the first in many fields in China and is another masterpiece of CREEC in the field of new standard rail transit.

At present, the new multi-system rail transit is becoming the “new favorite” of China’s urban rail transit construction.In response to China's call for “a country with strong transportation network” and the “innovation-driven development”, CREEC has developed and applied technologies such as medium-low speed maglev, straddle monorail, and modern tram, becoming a major pathfinder and an important practitioner in the field of new-system rail transit.

2016年，国家启动“十三五”重点研发计划——先进轨道交通重点专项“磁浮交通系统关键技术”：具体包括时速600公里的高速磁浮项目与时速200公里的中速磁浮项目。中铁二院是该重点专项中唯一一家同时参与承担了中速、高速磁浮交通系统关键技术研究课题的工程综合勘察设计单位。

In 2016, China launched the Key Project of Advanced Rail Transit of “Key Technologies of Maglev Transportation System” as an integral part of the “Thirteenth Five-Year Plan”, specifically including the high-speed maglev project with a speed of 600 km per hour and the medium-speed maglev project with a speed of 200 km per hour.CREEC is the only engineering integrated survey and design institute in this key project that has undertaken the research project of key technologies of medium and high-speed maglev transportation system at the same time.
