At 10:00, the final pair of steel rails was welded at the 1301-7 construction site, marking significant progress towards the line's operational readiness.  

Full track connection signifies that a continuous, seamless path has been created for trains. In this stage, short factory-produced rails are welded together to form long, unbroken tracks, enabling smoother and more efficient train movement. Following this milestone, testing trains powered by their own systems can operate within the tunnels, paving the way for further progress in electrification and operational trials.   

This achievement sets the stage for the next phases of construction, including power supply installation, communications systems, and mechanical and electrical engineering. The line is expected to achieve full electrification and see its first train roll off the production line by the end of this year.

The Phase I project of Metro Line 1 spans 57.46 kilometers, connecting Dongguanxi Station to Meitang Station. It traverses 10 towns and districts, including Wangniudun, Hongmei, Daojiao, Wanjiang, Nancheng, Dongcheng, Dalingshan, Songshan Lake, Dalang, and Huangjiang, with a total of 122.3 kilometers of track laid. The line comprises 16.58 kilometers of elevated track and 105.72 kilometers of underground track.

Once operational, Line 1 will have a maximum design speed of 120 km/h, forming a vital "+" shaped interchange with the existing Line 2. It will also connect seamlessly with Guangzhou and Shenzhen's metro systems, as well as intercity rail networks like the Guangzhou-Shenzhen Intercity Railway, the Foshan-Dongguan Intercity Railway and the Dongguan-Huizhou Intercity Railway. Key stations such as Wanghong Station, Civic Center Station (formerly Hongfu Road Station), and Dongchengnan Station will serve as major transfer hubs, significantly enhancing regional connectivity.  

With the completion of full track connection, Line 1 has now entered the final stages of construction. All stations, tunnels, and viaducts are now structurally complete. The project is now focused on completing electrification, signal system installation, and trial runs, aiming to meet its timeline for public operations.
