The depot that will run Thane’s Metro Line 5 has crossed 23% completion, the Mumbai Metropolitan Region Development Authority (MMRDA) said this week, as construction pushes through some of the softest ground on the corridor. The 27-hectare Kasheli depot, sited near the Kasheli toll plaza, will eventually stable and maintain around 30 trainsets for the 32-km line linking Thane, Bhiwandi, Kalyan and Ulhasnagar, according to Free Press Journal and Prahaar.

Why the depot is the hard part

Depots rarely make headlines the way stations do, but Kasheli’s location makes it the pacing item for the whole corridor. Soil surveys found marine clay sitting 6 to 9 metres below the surface, too soft to carry the depot’s tracks and workshop buildings without settling unevenly over time. MMRDA’s contractors are treating the ground with prefabricated vertical drains, which pull water out of the clay layer, followed by staged surcharge loading that presses the soil down in phases rather than all at once. It is slow, deliberate work, and it explains why a depot announced with fanfare in 2025 is only now approaching a quarter finished.

Environmental clearances for the site came through in August 2025, roughly a year behind the line’s own construction timeline elsewhere. MMRDA has responded by splitting the depot work into phases, so a limited number of stabling lines can be ready for train testing before the full workshop and yard are complete. Chief Minister Devendra Fadnavis and Deputy CM Eknath Shinde, who chairs MMRDA, both framed the update as evidence the project remains on track; Metropolitan Commissioner Sanjay Mukherjee credited the phased approach for keeping testing on schedule despite the ground conditions.

What it means for Thane, Bhiwandi and Kalyan commuters

Metro Line 5 is meant to be Thane’s answer to a stretch of the region that has grown fast and driven a lot of that growth on two wheels and shared autos, because rail options between Thane, Bhiwandi and Kalyan have stayed thin. A depot running behind schedule does not delay the line by itself, but it caps how many trains can be tested and certified before launch, which in turn limits how quickly the corridor can move from partial to full service. Residents along the route have watched elevated pillars rise for months; the depot update is the less visible half of that same promise, and it is the half that determines whether trains actually run reliably once stations open.

What to watch next

MMRDA has previously pointed to a stabling-line handover late this year to allow initial train testing while depot construction continues, with a target of December 2026 for the corridor’s first phase. That target has already slipped once. Whether the vertical-drain and surcharge-loading work stays on the pace MMRDA described this week will be the clearest signal of whether Thane commuters see trains running before the end of the year or into 2027.
