It has been reported that the trial run is expected to take place on October 26, with high-profile figures such as Chief Minister M.K. Stalin and Union Minister of Housing and Urban Affairs Manohar Lal Khattar anticipated to flag off the event. Sources have indicated that final confirmation of the date is expected in the coming days, reflecting the excitement surrounding this development for Chennai’s transport system.

The driverless train coaches, which were transported from Sri City, arrived at the Poonamallee depot facility on October 17. This marks a significant step in the city's metro expansion. The Chennai Metro Rail Limited (CMRL) has incorporated several new features in these trains to improve passenger comfort, including digital route displays and charging points for electronic devices, catering to the needs of tech-savvy commuters.

At the core of this project is the Rs 1.87 billion depot located at Poonamallee, which spans 40.5 acres and houses 17 buildings. The depot is essential for the maintenance and repair of the trains that will operate within the Phase II network, ensuring the system runs efficiently.

Currently, the train is positioned on the Inspection Bay Line, where checks on key systems such as circuits, brakes, ventilation, and air-conditioning are being carried out. CMRL officials are meticulously testing all components ahead of the trial run. The train will first undergo slow-speed tests of 10-15 kmph on the inspection track before transitioning to the 820-metre ballasted test track for its official trial run.

The Phase II project includes a crucial corridor between Poonamallee and Porur, part of the metro's corridor 4, which runs from Light House to Poonamallee. To support the full operation of this service, CMRL plans to prepare a total of 36 trains, with the next set of coaches expected to arrive from November onwards for further testing.
