railway is the key link of "the last kilometer" of railway construction, which is directly related to the train operation safety after the completion of the railway and the experience of passengers on the Internet, communication and in and out of the station. The post station project of Dalin railway includes "four power" including communication, signal, traction power supply and power supply system, as well as station building construction and decoration, disaster prevention and safety monitoring system, etc The project has the characteristics of high technical content, strict standard requirements, difficult precision control, multiple cross interfaces and complex construction organization

"the railway catenary is the key equipment to provide power for the train. During the construction, we should ensure that the height difference between the Catenary line and the rail surface is 6m, and within 50m, the height difference cannot be greater than 20mm; the Catenary line is zigzag relative to the center line of the line, and the adjustment error does not exceed 30mm." Meng Zhen, manager of Dalin Railway Project Department of China Railway First Bureau Group, said

it is understood that the Dalin railway needs more than 7000 new OCS pillars, bridge steel pillars, etc., nearly 1600 kilometers of OCS, communication optical cables and high and low voltage lines, 26 communication towers and 17 substations While erecting the first catenary pillar, the station building construction of Lincang railway station 150 kilometers away from Weishan is also in full swing. The total construction area of new station buildings along Dalin railway is about 90000 square meters, and the construction sites are all over Dali and Lincang of Yunnan Province Fan Weiping, deputy director of Yunnan West Railway Construction Headquarters of China Railway Kunming Bureau Group Co., Ltd., said that since the start of construction at the end of 2016, all works of Dali Lincang railway have been advancing as planned, including 89% of bridges and 84% of tunnels.
