At 9 o’clock in the morning on November 3, 55,571 test EMUs were dispatched from Xi’an North Station to test the parameters of the section operation diagram from Xi’an North to Qingyang, and the High Railway Xi’an speed entered the trial operation stage.During the test operation, three stages are used: parameter testing of the train diagrams, simulation of failures and emergency rescue drills, and driving tests according to the diagrams to verify the adaptability of the transport organization of each system under normal and abnormal conditions, and to check whether the driving organization can meet the requirements. Full map operation requirements, inspection equipment failure, and emergency response capabilities under natural disaster conditions provide the technical basis for refining the scientific and reasonable transportation organization plan.

Xiyin High-Speed Railway is an important part of the “Eight Vertical and Eight Horizontal” High-Speed Railway Main Passages and Sea-Filled Passages in the National “Medium and Long-Term Railway Network Planning”.Crossing the edge of the Mu Us desert and the world’s largest loess plateau, Dong Zhiyuan, is the first ballasted high-speed railway built on the longest section of the loess layer in China, and it is also the railway of high speed with longer ballast built once in the country under construction. .
Construction of the Xi-Yin high-speed railway began in late 2015, with a total length of 618 kilometers, of which the Shaanxi section is 193 kilometers and the Ganning section is 425 kilometers.Designed speed of 250 kilometers per hour, 350 kilometers per hour reserved for high-speed ballast train acceleration conditions, There are a total of 20 stations on the entire line. After opening,The train from Xi’an to Yinchuan will be shortened from 14:00 today to about 3 hours.
The same day,Yantong high-speed train completed the acceleration test step by step. The high-speed comprehensive inspection train successfully traveled the entire distance at a speed of 385 kilometers per hour. The subsequent test run will be transferred.
From October 25 to November 3, the comprehensive high-speed inspection train in the Yantong high-speed train started from 180 kilometers per hour and went through 16 degrees of speed to increase the speed gradually, and finally reached a speed of 385 kilometers per hour.
The test exhaustively tested the state of the track geometry, the dynamic response of the EMU, the geometric parameters of the catenary, the pantograph and the performance of the net current, the communication system and other test items in different degrees of speed to meet the performance of the train operating conditions, marking the joint adjustment of the Yantong high-speed railway The joint test has progressed gradually.
Yantong high-speed railway is an important part of the coastal railway in the main channel of the “eight vertical and eight horizontal” high-speed railways in the national “medium and long-term rail network planning”.It is a key project to complement the last stretch of the coastal rail corridor that runs through eastern ChinaIt starts at the Yancheng Station of the Xuyan Railway in the north and reaches the Nantong West Station of the Shanghai-Sutong Railway in the south. There are 6 stations. The main line is 156.6 kilometers long and the design speed is 350 kilometers per hour.
After completion,It will also become the first high-speed railway line with a speed of 350 kilometers per hour in North Jiangsu.
In addition to the Xiyin high-speed rail and the Yantong high-speed rail, there are 8 lines that will open later this year, namely: Lianzhen Section Huaizhen High-speed Railway, Lianxu High-speed Railway, He ‘High-speed Railway an, Beijing-Shenzhen High-Speed Railway Beijing-Chengdu Section, Beijing-Xiong Interurban Railway From Daxing Airport to Xiong’an Section, Taijiao High-speed Railway, Wei-Lai High-speed Railway, Fuping Railway.
