China News Service, Guangzhou, August 31 (Guo Jun, Deng Lianxu, Tan Couyun) A reporter learned from the China Railway 25th Bureau Electric Company on the 31st that at 4:7 am that day, the Guangzhou-Shenzhen Railway Signal Interlocking Reconstruction Project Shenzhen and Sungang , The interlocking renovation of the three stations in East Shenzhen, and the replacement of signal equipment were opened on time and delivered to the station. So far, the signal interlocking transformation project of the entire Guangshen Railway has been successfully completed, which will further improve the safety of railway operation and provide safe and reliable preconditions for the operation of high-density passenger trains during the National Day and Mid-Autumn Festival.
The renovation of the Shenzhen, Sungang, and Shenzhen Dongsan Stations this time mainly involves professional content such as signal, communication, power and housing construction.

China Railway 25 According to Zhang Yongjie, the project technical leader of the Electricity Company.
The existing lines have high safety risks and tight schedules. Since entering the site in August 2019, the construction party has optimized the construction plan, organized the construction in a scientific and orderly manner, and has effectively grasped the safety technical disclosure and the existing line construction safety education and training to ensure safe production. In nearly 300 existing line blockade constructions, all Safety, punctuality, zero hidden danger, zero accident.
In the face of the sudden new crown pneumonia epidemic, in order to ensure the progress of the project, the project construction staff worked overtime in the dormitory during the self-isolation period to arrange and align the signal boxes, moved the construction site to the isolation area, and made the staff dormitory " "Production workshop" maximizes the utilization of time and provides a solid guarantee for alleviating the pressure of the construction period.
"After the completion of this transformation, the Guangzhou-Shenzhen Railway can effectively improve the safety and reliability of equipment, reduce the intensity of electrical maintenance, reduce the risk of equipment safety hazards, further improve transportation efficiency, and meet the growing demand for passenger transportation on the Guangzhou-Shenzhen Railway." Yan Guoyin said.
The Guangzhou-Shenzhen Railway is a commercial operation pilot line for China's high-speed railway and passenger dedicated line; the track line runs along the Guangzhou-Kowloon Railway through Guangzhou, the center of South China, Dongguan, the world factory, and Shenzhen, a special economic zone, connecting Guangzhou and Shenzhen and running through the northern and eastern areas of Dongguan. A fast channel connecting the Guangzhou-Foshan metropolitan area of the Pearl River Delta and the east bank urban agglomeration will be formed, and the three modern cities will be integrated into the one-hour living circle.
