The company immediately set up a Lixiang line project team to ensure the implementation of the project according to the needs of customers, the company's technical personnel with many years of railway electrification product design experience and experience in providing under-train power supply for the 160-kilometer plateau car of Lalin Line, redesigned Lixiang railway line products, increased the heat dissipation of under-vehicle power products and fan fault feedback monitoring functions, etc., to overcome the difficulties of tight delivery time and heavy production tasks, and fully ensured the delivery of the project products on schedule, according to quality and quantity under the company's lean management.
The successful passage of the first article appraisal is an affirmation of Huashi's ability to complete the project with high speed, efficiency and high quality, and lays the foundation for the Lixiang Line project to enter the pre-loading and delivery.

Tips: Lixiang Railway, also known as Lixiang Line, is a Class I electrified railway of the National Railway connecting Lijiang City with Shangri-La City, Diqing Tibetan Autonomous Prefecture, in Yunnan Province, China, and is an integral part of the "western railway network" of China's medium- and long-term railway network planning. Because the Lixiang section of the Yunnan-Tibet Railway starts from Lijiang Station in the south, goes north through Tiger Leaping Gorge, Xiaozhongdian Town to Shangri-La City, passes through Yulong Naxi Autonomous County of Lijiang City, Shangri-La City of Diqing Tibetan Autonomous Prefecture, passes through Yulong Snow Mountain, Haba Snow Mountain, Tiger Leaping Gorge and other scenic spots along the way, there are many beautiful scenery along the road, known as the "most beautiful heavenly road". The Lixiang Railway started construction on October 28, 2014 and is expected to be put into operation by the end of 2022.
After the completion and operation of the Lixiang Railway, it will connect with the existing Kunming-Lijiang Railway, ending the history of the lack of railway access in Diqing Tibetan Autonomous Prefecture in Yunnan Province, and will also greatly make up for the shortcomings of the railway network and transportation services in northwest Yunnan, and link the tourist destinations of Dali, Lijiang and Shangri-La in Yunnan to promote the economic and social development of tourism along the line.
