7月3日，在埃及总统塞西的见证下，由中国和埃及两国合作建成的埃及斋月十日城铁路通车试运行，这是埃及第一条电气化铁路。中铁二院工程集团有限责任公司（以下简称“中铁二院”）代表中国中铁股份有限公司作为项目的总承包方之一，全程参与了项目的勘察设计工作。项目建设过程中实现了哪些创新突破？有哪些突出亮点？中埃两国建设者如何通力合作？取得了哪些成功经验？通车前夕，记者围绕这些问题，线上专访了在埃及的中铁二院副总经理张雪才。
On July 3, Egyptian President Abdel-Fattah al-Sisi witnessed the trial run of the 10th of Ramadan Railway. Jointly built by China and Egypt, it is the first electrified railway in Egypt. As one of the engineering, procurement, and construction (EPC) contractors on behalf of China Railway Group Limited (CREC), China Railway Eryuan Engineering Group Co., Ltd. (CREEC) was involved in the whole process of the project’s survey and design. What innovative breakthroughs have been achieved during project construction? What are the highlights? How did China and Egypt cooperate with each other? What successes have been achieved? To find answers to these questions, the journalist conducted an online interview with CREEC Deputy General Manager Zhang Xuecai before the opening of the railway.
记者：您参与了从亚吉铁路到埃及斋月十日城铁路等非洲铁路的实施，您所在的中铁二院负责项目的勘察设计全过程，请介绍一下埃铁项目在设计上的创新之处。
Journalist: Could you please introduce the innovations in the design of the 10th of Ramadan Railway as your company CREEC was involved in the whole process of the project’s survey and design and you have participated in the implementation of some railways in Africa including this project and the Addis Ababa-Djibouti Railway.
张雪才：中铁二院作为铁路行业勘察设计的龙头企业，参与了埃铁项目从谈判、方案规划到勘察设计、配合施工等全过程。项目在设计阶段划分、图纸表达习惯和深细度、设计管理等方面均与国内有很大差别，中铁二院设计团队勇挑重担，充分发挥设计引领优势，成功使设计得到全面批复。
Zhang Xuecai: CREEC, as a leading enterprise in railway survey and design, participated in the whole process of the 10th of Ramadan Railway, from negotiation, scheme planning, survey and design, and cooperative construction. This project differs from railways in China in terms of such aspects as the division of design phases, the drawings’ expression pattern and level of detail, and design management. CREEC shouldered the important responsibilities and fully leveraged its leading advantages in design, and finally its design was approved.
首先，这是埃及首次脱离轨道电路应用无缝线路设计的铁路项目，设计团队按照中国设计标准，广泛参考引用埃及本地规范或工程实例完成项目设计，以保证铺设无缝线路的安全。其次，双层侧式地面站的车站建筑方案既能满足埃及乘客需求，又融入了中国建筑精华，成为埃及的样板车站。第三，抗震方案设计综合了中欧的抗震理念，通过调整抗震构造提高结构整体抗震性能，同时实现了结构设计的经济性和高效能。第四，列车通过了国际标准列车火灾燃烧试验，是耐风沙、低噪音、大载客量的定制化特殊车辆。
Firstly, the 10th of Ramadan Railway is the first railway project that replaces the track circuit with the continuous welded rail (CWR) in Egypt. To complete the project design, the design team adopted Chinese design standards and referred to lots of Egyptian standards or engineering practices, thus ensuring the security of CWR laying. Secondly, the double-story side platform station above the ground has become a model in Egypt. Its construction plan meets the needs of Egyptian passengers while incorporating the essence of Chinese architecture. Thirdly, in terms of the seismic design, both the Chinese and European concepts were used. The design team improved the overall seismic performance through structure adjustment and achieved economical and efficient structural design. In addition, the customized train passed the international fire and combustion experiment. Besides resistance to sandstorms, it also features low noise and a large passenger capacity.

张雪才：埃铁项目是中国轨道交通全产业链走进埃及的第一个重大项目，具有技术标准高、设备比重高、附加值高的特点，在埃及创造了多项“第一”：中国电客车、工程车、车辆段工艺设备首次进入埃及，是埃及首条采用CBTC信号系统的轨交线路，首次应用交流27.5kV牵引供电系统于埃及轨道交通，首次采用集中系统维保（MMS）方案，首次引入并应用综合接地技术体系，将国际领先的人脸识别、智能检测功能运用于视频监控系统中，首次在“一带一路”轨道交通工程项目中采用满足欧标的弱电集中电源双UPS、双母线供电系统……这些使中国设计、中国方案、中国设备、中国工艺在埃及市场创立了良好口碑。
Zhang Xuecai: The 10th of Ramadan Railway is Egypt’s first major project involving the whole industrial chain of China’s rail transit. It features high technical standards, high proportion of equipment and high added value. It has broken new ground for Egypt in multiple aspects as follows. Firstly, it is the first time for Egypt to introduce China’s electric trains, engineering vehicles and process equipment of the vehicle depot. Secondly, it is the first railway in Egypt that adopted the Communication Based Train Control (CBTC) signal system and adopted electric traction power supply using alternating current (AC) at 27.5 kilovolts (kV). Besides, it is also Egypt’s first railway using the Maintenance Management System (MMS), introducing the comprehensive power system grounding technology and applying the international leading face recognition and intelligent detection to the video monitoring system. Moreover, this is the first time to use the dual uninterruptible power supply (UPS) system and dual busbar power supply system that meet the European standards in a rail transit project along the Belt and Road. These efforts have established a good reputation in the Egyptian market for Chinese design, solutions, equipment and technology.

记者：埃铁项目实施过程中，中埃两国建设者通力合作，促成了铁路如期通车试运行，请介绍一下项目实施过程中两国建设者的合作情况。
Journalist: During the implementation of the 10th of Ramadan Railway Project, the builders of China and Egypt went all out to open the railway as scheduled. Please brief us on the cooperation between Chinese and Egyptian builders on the project.
张雪才：埃铁项目是中埃两国“一带一路”合作标志性项目之一，采用中国技术和装备，由10多家埃及企业和20多家中国企业共同实施。其中，埃及企业负责土建、装修和轨道施工，中国企业负责车辆段工艺设备和机电设备的安装、机电系统的综合联调。由于中埃双方在作息时间、文化理念、思维方式等方面均存在较大的差别，特别是机电安装与装修的接口众多、施工工序相互制约，而工期又异常紧张，这加大了总承包方协调管理的难度。中方管理团队统筹安排，充分尊重当地文化习俗，使双方企业作业无缝衔接、有序开展，确保了项目的顺利推进。
Zhang Xuecai: The 10th of Ramadan Railway Project is one of the landmark projects of the China-Egypt cooperation under the Belt and Road Initiative. Utilizing Chinese technology and equipment, the project was implemented by over 10 Egyptian enterprises and over 20 Chinese enterprises. Among them, Egyptian enterprises were responsible for civil construction, decoration and track construction, while Chinese enterprises took charge of the installation of process equipment and electromechanical equipment in the depot and the comprehensive joint commissioning of electromechanical systems. However, the general contractor faced enormous difficulties in coordinating and managing the project because of the differences between China and Egypt in terms of work and rest time, cultural concepts, and ways of thinking, as well as the numerous interfaces of electromechanical installation and decoration, the mutual restriction of construction procedures, and the extremely tight construction schedule. In response to these issues, the Chinese management team made overall arrangements and fully respected local culture and customs, so that the operations of the enterprises of both sides were seamlessly connected and carried out in an orderly manner, which ensured the smooth progress of the project.
两国建设者通力合作，中国企业高度重视培养埃及青年技术人员，在疫情特殊时期展示了“中国速度”，传授了“中国经验”，谱写了新时代中埃合作的新篇章。
The builders of the two countries made concerted efforts. Chinese enterprises prioritized the training of young Egyptian technicians. In the fight against the pandemic, they demonstrated “Chinese speed” and passed on “Chinese experience”, writing a new chapter of China-Egypt cooperation in the new era.
