The section from Xiaojie Station to Xizhan Station, which is about 20 kilometers long, has been opened.
On July 8, 2025, the northern section of Tianjin Metro Line 4 starts its initial operation. This section from Xiaojie Station to Xizhan Station passes through Beichen, Hebei, and Hongqiao districts, with a total length of approximately 20 kilometers.

To facilitate track maintenance, the Maglev line's operation mode has been adjusted from dual-track to single-track operation.
The East Extension of Line 1 spans a total length of 16 kilometres and features 10 stations.
The operational mileage of the Guangzhou Metro network has reached 751.1 kilometers.
