Coimbatore Metro Rail Update

Coimbatore's metro dream has been in the making for over a decade, and 2025-26 has turned into the project's most eventful stretch yet. The Detailed Project Report (DPR), prepared by Chennai Metro Rail Limited (CMRL), proposes a 34.8 km elevated network split across two lines. Corridor 1 runs from Ukkadam Bus Stand to Coimbatore International Airport via Avinashi Road, covering 18 stations including GKNM Hospital, Fun Republic Mall, Coimbatore Medical College, and Neelambur. Corridor 2 connects Coimbatore Junction to Valiyampalayam Pirivu along Sathyamangalam Road, touching Gandhipuram Bus Stand, Saravanampatti, and Ganapathy Pudur. The two lines meet at an interchange north of Coimbatore Junction.

The Tamil Nadu government submitted this DPR to the state in July 2023, and it received state-level approval in February 2024. The project carries an estimated price tag of roughly ₹10,740 crore, and CMRL has planned it as a lighter Metrolite-style system, running three-coach trains with a capacity of up to 700 passengers instead of the heavier four-coach rakes used in Chennai. To keep land acquisition minimal, engineers plan to install viaduct pillars every 30 metres along the road edge rather than acquiring wide strips of land, with a depot planned on 16 hectares at Neelambur.

The project hit a serious roadblock in November 2025. On November 14, the Union Ministry of Housing and Urban Affairs (MoHUA) returned the DPRs for both Coimbatore and Madurai metro projects, citing the National Metro Rail Policy 2017's population threshold of 20 lakh. The Centre's communication used 2011 Census figures, under which Coimbatore's population stood at 15.84 lakh, even though the city's population is well above 20 lakh by 2025 estimates. The Centre reportedly suggested cheaper alternatives such as a Bus Rapid Transit System (BRTS) instead of rail-based metro.

The decision triggered a political storm. Chief Minister M.K. Stalin wrote directly to Prime Minister Narendra Modi on November 22, 2025, expressing disappointment and urging MoHUA to reconsider, pointing out that Tamil Nadu's high per-capita vehicle ownership makes rail-based transit essential for its growth engines. He also questioned why smaller BJP-ruled tier-II cities had received metro approval despite similar population profiles. State ministers and DMK allies held protests in both cities, framing the rejection as a fight for Tamil Nadu's infrastructure rights.

By January 2026, the state had shifted from protest to paperwork. Tamil Nadu began preparing a revised submission with additional justification and data to address the specific gaps MoHUA had flagged, routing the updated documents back through the state government for a fresh push at central approval. CMRL had earlier proposed combining the Coimbatore and Madurai proposals into a single procurement package, since bulk ordering of trains and signalling systems could speed up execution once approval comes through.

For homebuyers and investors, this means the metro remains a 'when', not an 'if' at this point, but the timeline has clearly slipped from the earlier target of an operational Phase 1 by 2027. Once central approval and international funding (from agencies like JICA or ADB) are locked in, officials have indicated land acquisition alone could take up to two years, followed by a roughly three-year construction period. That puts realistic completion well into the early 2030s if approval comes through in the near term.

What this means on the ground: localities along Avinashi Road and Sathy Road — from Peelamedu and Ganapathy to Saravanampatti and Neelambur — stand to see the sharpest connectivity upside whenever construction begins. Property buyers evaluating these corridors should track the DPR resubmission closely, since metro-adjacent addresses in other Tier-II cities have historically seen value appreciation well before the first train runs, but only once construction visibly starts on the ground.
