Track construction of the south extension of Metro Line 5 has been completed, while the installation of overhead electricity systems will be completed by the end of the month, allowing for trial operations to begin this year.

During track construction, floating slabs were installed beneath the tracks to reduce vibrations when trains are running at high speed. As the first elevated Metro line that runs across the Huangpu River, the tracks on the bridge crossing the river are designed to adapt to possible bridge deformations so that passengers will have a safer and more comfortable trip. Meanwhile, the existing Line 5 trains and stations are also undergoing an upgrade to allow six-carriage trains to replace the current four-carriage ones. The current trains have been criticized for being incapable of managing large passenger flows during rush hours.
