A total of 5 locomotives, 17 rail cars, 4 large tamping machines, 2 welding machines and 130 pneumatic vehicles were invested in the whole line, Nearly 10000 cubic meters of ballast were loaded every day, and three shifts of construction personnel were organized to work day and night. Finally, the goal of track laying node of the main line was successfully achieved. It is understood that the subgrade, bridge, tunnel and other main works of the project have been completed, the construction of communication, signal, power and catenary have been basically completed, the communication transmission system has been connected to the existing network of China Railway Guangzhou Bureau Group, and the catenary is planned to be electrified on December 8; A total of 42539 square meters of freight production and living houses have been built along the whole line, accounting for 89.8% of the total design.
