Chinanews, Lu'an, September 17 (Liu Honghe) At 4:30 am on September 17, after nearly 6 hours of intense construction by more than 470 construction workers, Anhui Lu'an Railway Station successfully completed the decommissioning of the station signal control system And the traffic dispatch system adjustment project II level blockade construction.
This marks the completion and official opening of the Lu'an Station high-speed railway and the general-speed railway branch.

According to reports, Lu’an Station is an interchange station of Shanghai-Chengdu High-speed Railway, Ningxi Pu-speed Railway, and Fu-Liu Pu-speed Railway. Every day, 135 pairs of EMUs, 52 pairs of ordinary-speed passenger cars, and 75 pairs of freight trains are handled. Very busy, and a signal system controls two speed trains.
"With the opening of the He-Hangzhou high-speed railway, the Ningwu dispatching station, where it is connected to Lu'an Station, has become more overwhelmed. In order to reduce the mutual interference between the operation and maintenance of the existing high-speed and normal-speed railways, ensure the dispatch and command The station plans to separate the signal control systems of high-speed railways and ordinary-speed railways.” said Xu Chenguang, deputy secretary of the general branch of the Lu’an Station Coalition at the Hefei Train Department of China Railway Shanghai Bureau Group Co., Ltd. There are Lu'an Station platforms 1-5 (Road 1-7) for Lu'an Hurong Expressway, and platforms 6-7 (Road 8-17) for Lu'an Pu Speed Field. The dispatching platform of Lu'an Station is also under construction. The adjustment and split have been completed, which optimizes the jurisdiction of the train dispatching station and further improves the efficiency of platform transportation."

It is understood that the signal control and dispatching and command systems of Lu'an Station have been split and adjusted, with a large scope of influence, and the coordination and cooperation units involved 18 stations and sections of Wuhan, Beijing and Shanghai 3 railway bureaus to cooperate in construction.
On the day of opening and construction, 6810 cables must be dismantled and wired within 150 minutes, and most of them must be implemented within a limited work area of less than 10 square meters. Only after the wiring is completed can subsequent system tests and tests be carried out.
According to Liu Linbo, Chief Engineer of the Lu'an Station Reconstruction Project of the China Railway Fourth Bureau Electrification Company: “The high-speed and normal-speed railway branch is the first in China. The technical difficulty is very high in implementation. In order not to affect the train operation, only 4 jobs per week. Up to 5 days, and 90 minutes of night operation skylights are needed every day, even if a piece of wiring is connected incorrectly during construction, it may cause unimaginable consequences."
Since the start of construction in October 2019, the China Railway Fourth Bureau Electrification Company has formulated detailed safety measures to avoid the impact on transportation and production in response to the actual situation of on-site construction. It has also innovatively used the new "auxiliary support ring + connecting copper pipe". Technology, reasonable deployment of human and material resources, improved labor efficiency, successfully solved a series of problems such as tight construction period, technical difficulty, wide coverage, and high safety risk, and promoted the construction nodes in an orderly manner to ensure the safety and control of the entire process.

"The Lu'an Station after the Gaopu branch has laid a good foundation for the convenient operation of the Hewu Railway and the Fu-Liu Railway and the better use of the role of the'cross hub' for inter-city communication between Lu'an and the central and eastern urban agglomeration." China Railway Fourth Bureau Du Junmo, deputy secretary of the party committee of the Electrification Company, said, “It also provides greater convenience to meet the passenger transportation needs and labor output flow in the old revolutionary areas, and effectively enhances the'bloodmaking' in the poverty-stricken areas of Lu'an in the country's fight against poverty.
