Joka-Esplanade Metro: The Purple Line Inches Toward Central Kolkata

There is a particular kind of patience that South Kolkata has learned to hold onto over the years, the patience of watching tunnel boring machines disappear underground and waiting, month after month, for word of their progress. That patience found reward this year. In a season that has felt unusually eventful for the Joka-Esplanade corridor, two of the project's tunnel boring machines, Durga and Divya, broke through at Victoria station within weeks of each other, marking one of the most tangible milestones yet in a metro line that Joka residents have watched rise slowly since 2022. As per reports, TBM Durga completed its journey in July 2026, while its sister machine Divya followed in August, and together they closed out the twin-tunnel work between Khidderpore and Victoria stations, a 1.72-kilometre stretch of underground construction through some of the city's most difficult soil.

Today, the Purple Line's public face is still modest by design. The Joka to Majerhat stretch, an elevated run of roughly 7.74 kilometres, has been carrying passengers since the initial section opened in December 2022 and was extended to Majerhat in March 2024. It is a working, if truncated, metro connection, and Kolkata Metro recently widened its usefulness further by introducing Saturday services on the corridor from 22 November 2025, running 40 trips a day at 21-minute intervals to serve the IT workforce that commutes through the area. What lies beyond Majerhat, however, is where the real transformation for Joka is being built, quite literally underground.

The section from Majerhat to Esplanade forms Package UG1, a demanding 5.05-kilometre underground stretch from Mominpur to Esplanade that includes stations at Khidderpore, Victoria, Park Street and Esplanade itself. With both tunnelling machines through Victoria, engineers now expect the pace to pick up as work moves beneath the Kolkata Maidan toward Park Street, the next major staging point before the line reaches the city's commercial heart. Metro Railway officials have indicated that the underground portion is being targeted for completion toward Park Street by the end of this year, though a fully operational Joka-to-Esplanade run, connecting with the Blue and Green lines, remains a matter of a further year or two once testing and commissioning are accounted for.

Even as this core corridor nears its underground milestones, planners have floated an ambitious bookend to the project. A proposal sent to the Railway Board suggests extending the Purple Line by a further 1.6 km beyond Esplanade to Eden Gardens, a change from the earlier plan of linking Eden Gardens to Esplanade purely by a pedestrian subway. This revision would give commuters walking access to Strand Road, Babughat, the Calcutta High Court and BBD Bagh directly from a new terminal station, while also sparing a cluster of trees near Manohar Das Tarag that the original subway route would have required felling. On the southern end, a parallel proposal would stretch the line 1.7 km past the existing Joka terminus to IIM Joka, with sources suggesting the possibility of further extensions beyond that point in future phases. Together, these two additions would take the Purple Line's total length to around 18 kilometres, up from its present 14.1 km footprint.

For homebuyers, the metro's slow but visible progress has already begun reshaping what Joka is worth. Flat prices in the locality currently sit in the range of roughly Rs 5,250 to Rs 6,250 per square foot, with the average hovering near Rs 5,750, and values have risen about 5.5 percent over the last year, 13.9 percent over three years, and nearly 80 percent over five years, according to 99acres data. Independent market analysis places the average closer to Rs 6,000 per square foot with a range from Rs 3,800 to Rs 9,000 depending on the specific project and its distance from the operational stretch, noting that Joka already offers a rare combination in Kolkata: live, functioning metro access at a price point well below Rs 6,500 per square foot. Rental yields in the area currently average around 3 percent, a figure typical of an emerging rather than fully mature micro-market, which is precisely the phase analysts believe Joka is now in.

Godrej Properties has been among the more visible developers backing this shift, and its footprint in Joka has grown steadily as the metro story has unfolded. Godrej Se7en, the group's flagship township here, spans roughly 20 acres with over 75 percent open space and offers 2 and 3 BHK homes with prices starting near Rs 53 lakh, while its newer phase, Elevate at Godrej Se7en, adds a rooftop sports zone and sits within walking distance of the now-operational Joka metro station. The developer has also entered the plotted-development segment in a meaningful way with Godrej Zen Estate, a 54-acre, Bali-themed low-density project offering plots from 1,200 to 2,400 square feet with prices starting around Rs 45 lakh, positioned about fifteen minutes from the Joka metro corridor. Earlier, Godrej Properties had signalled its confidence in the micro-market by announcing an agreement to develop a residential project in Joka offering close to 277,000 square metres of saleable area, a move that saw its stock rise more than 5 percent on the announcement.

What should a buyer take from all this? The honest answer is a measured one. Joka's present value proposition rests on infrastructure that already exists, not infrastructure that is merely promised, and the elevated Joka-Majerhat stretch is real, running, and adding daily utility for thousands of commuters. The Esplanade connection, now visibly advancing with each tunnel breakthrough, is the upside that long-term buyers are pricing in gradually rather than all at once. For those weighing a purchase in this corridor, the sensible approach is to anchor decisions in what is operational today, treat the Esplanade and Eden Gardens extensions as a multi-year tailwind rather than an immediate trigger, and choose a developer whose delivery record, like Godrej's expanding Joka portfolio, gives some assurance that the promise on paper will eventually meet the platform on the ground.
