8月13日8时许，随着55880次检测列车从成都东站驶出，标志着新建四川成都至青海西宁铁路镇江关至黄胜关段（以下简称“川青铁路镇江关至黄胜关段”）联调联试工作圆满完成，正式进入运行试验阶段。
川青铁路是连接四川省成都市与青海省西宁市的骨干线路，全长约836公里，设计时速200公里，是国家Ⅰ级双线铁路。其中，镇江关至黄胜关段全长约70公里，设镇江关、松潘、黄龙九寨和黄胜关等4个车站，预计将极大便利沿线群众的出行，对推动沿线经济社会发展具有重要意义。
此次运行试验主要包括故障模拟、应急救援演练、列车运行图参数测试和按图行车试验等项目，旨在检验高铁线路各系统在正常与非正常条件下的运输组织适应性，验证行车组织方式是否满足运营要求，为完善科学合理的运输组织方案提供技术依据。
成兰铁路有限责任公司川青指挥部指挥长李群表示，项目自开工以来，各参建单位克服了地质条件复杂、施工难度大、高原缺氧、交通不便等困难，确保了工程进度和质量安全。在联调联试过程中，相关单位精调、精捣线路，消除了缺陷，为运行试验的启动创造了前提条件。
川青铁路镇江关至黄胜关段作为“八纵八横”高铁网的重要组成部分，其开通运营将有效促进区域经济一体化，带动沿线旅游资源开发，提升区域交通枢纽地位，对促进区域经济社会发展和民族团结具有深远意义。
随着川青铁路镇江关至黄胜关段进入运行试验阶段，预计将进一步优化和完善铁路运输服务，为沿线民众提供更加便捷、舒适的出行体验，为沿线经济社会发展注入新的动力。

Title: Phase of Jingjiangkou to Huangshengkou on Chengdu-Qinghai Railway Enters Operational Test Phase to Boost Regional Socio-economic Development
Article:
At around 8:00 a.m. on August 13, with the 55880 train detection vehicle departing from Chengdu East Station, it marked the completion of the comprehensive commissioning of the new Chengdu to Qinghai railway section from Jingjiangkou to Huangshengkou (referred to as the “Jingjiangkou to Huangshengkou section of the Chengdu-Qinghai Railway”), officially entering the operational test phase.
The Chengdu-Qinghai Railway connects Chengdu, Sichuan Province, with Xining, Qinghai Province, serving as a backbone line with a total length of approximately 836 kilometers, designed at a speed of 200 kilometers per hour, and is a National Grade I double-track railway. The Jingjiangkou to Huangshengkou section is about 70 kilometers long, with four stations including Jingjiangkou, Songpan, Huanglong Jiuzhaigou, and Huangshengkou, expected to greatly facilitate the travel needs of the local population and is of great significance for promoting regional socio-economic development.
The operational test includes various items such as fault simulation, emergency rescue drills, train operation diagram parameter testing, and operation according to the train schedule, aiming to test the adaptability of the transportation organization system under normal and abnormal conditions, verify whether the traffic organization method meets operational requirements, and provide technical basis for the establishment of a scientific and reasonable transportation organization plan.
Li Qun, the commander of the Chengdu-Lan Railway Company’s Chengdu-Qinghai Command, stated that since the commencement of construction, all participating units have overcome complex geological conditions, great construction difficulties, high-altitude hypoxia, and inconvenient transportation to ensure the progress and quality of the project. During the comprehensive commissioning, relevant units meticulously adjusted and repaired the tracks, eliminating defects and creating the prerequisite conditions for the commencement of the operational test.
The Jingjiangkou to Huangshengkou section of the Chengdu-Qinghai Railway, as an important part of the “Eight Verticals and Eight Crosses” high-speed rail network, its commencement of operation will effectively promote regional economic integration, stimulate the development of tourism resources along the line, enhance the regional transportation hub status, and have a profound significance for promoting regional socio-economic development and ethnic unity.
With the Jingjiangkou to Huangshengkou section of the Chengdu-Qinghai Railway entering the operational test phase, it is expected to further optimize and improve the railway transportation service, providing the local population with a more convenient and comfortable travel experience and injecting new momentum into the socio-economic development along the line.
