Shaanxi section of Yinxi high speed railway starts track laying

The reporter learned from China Railway Xi'an Bureau Group Co., Ltd that in the morning of November 28, the Shaanxi section of Yinxi high speed railway officially entered the track laying stage. A 6031 a 6031 Yinxi high speed railway is laid by the combination of ballasted and ballastless track. The tunnel group adopts ballastless track, and other sections adopt ballasted track. There are as many as 14 ballasted and ballastless transition sections, which make the construction organization difficult and the track laying technology and equipment alternate frequently. According to

, the ballasted track laying adopts the most advanced CPG500 type track laying unit in China, which can lay 500 meters long rails at one time. It has the advantages of high degree of mechanization, long continuous operation time and high efficiency index. It can realize the synchronous mechanized construction of rail laying and sleeper laying.

at the same time, the construction company, through the project Transportation Command and management system, realizes the full coverage of track laying transportation scheduling, process real-time monitoring, real-time communication, safety early warning, track laying construction information management, etc. to ensure the smooth completion of track laying in Shaanxi section of Yinxi high-speed rail. The

Yinxi high speed railway is an important part of the "eight vertical and eight horizontal" high speed railway network package (yinhaitong Road) in the national medium and long term railway network planning, which is expected to open by the end of 2020. After the line is opened, the train operation time from Xi'an to Yinchuan will be shortened from the current 14 hours to less than 3 hours, and the travel time of passengers will be greatly shortened.
