Kolkata Metro Orange Line: Sector V Extension Expected by December 2026

commuters in Kolkata are anticipating a major upgrade to the city's transit network as the কলকাতা মেট্রো (Kolkata Metro) Orange Line extension moves toward completion. The stretch connecting Kavi Subhash to Sector V is currently expected to be open for passengers by December 2026, potentially serving as a Christmas gift for the city's residents and IT professionals.

Currently, operational services on this line run from Kavi Subhash to Beleghata. The final phase of the project aims to bridge the gap from Beleghata to the IT hub of Sector V, significantly reducing travel time for thousands of daily office-goers.

Current Progress and the Chingrihata Milestone

Work is reportedly progressing on a "war footing" to meet the year-end deadline. A critical breakthrough has occurred at the Chingrihata section, where girder installation on pillars is now complete, successfully linking the Gaurkishore Ghosh metro station with the rest of the line. According to reports, track-laying work has already advanced by approximately 60%.

Beyond the tracks, several technical activities are happening simultaneously to ensure the line is ready for testing:

• Infrastructure: Ongoing cement coating, installation of iron structures, and drilling.
• Systems: Rapid completion of the signaling system is currently underway.
• Connectivity: The installation of the third line is the next major step following the girder completion at the Chingrihata junction.

Timeline to Launch: The CRS Inspection

While the December opening is the target, the official launch depends on safety certifications. The Commissioner of Railway Safety (CRS) is expected to inspect the entire stretch and provide the necessary clearance by late November 2026. This inspection is the final regulatory hurdle before the line can be opened to the general public.

The project has seen a recent surge in momentum; reports indicate that work which had been stalled for two and a half years was accelerated and completed in just 90 days following new administrative permissions. Railway Minister Ashwini Vaishnaw has reportedly been monitoring the progress closely to ensure the December timeline is met.
