Centre Reaffirms Rejection of Coimbatore and Madurai Metro Rail DPRs

Summary

The Union Ministry of Housing and Urban Affairs (MoHUA) has reaffirmed its decision to reject Tamil Nadu's renewed Detailed Project Reports (DPRs) for Metro Rail projects in Coimbatore and Madurai. The Centre maintains that the two cities do not presently justify the investment required for a full Metro system and has recommended a Bus Rapid Transit System (BRTS) as a lower-cost alternative.

Background

Metro Rail projects in India are sanctioned under the National Metro Rail Policy, 2017, which sets eligibility criteria including a minimum city population of about 20 lakh (2 million) and a favourable cost-benefit ratio. Tamil Nadu had prepared DPRs proposing two Metro corridors for Coimbatore and one for Madurai, submitted through Chennai Metro Rail Limited (CMRL).

Previous Developments

The Union government had earlier returned the same DPRs in November 2025, citing that Coimbatore and Madurai did not meet the 20-lakh population threshold under the 2011 Census. The state government resubmitted a revised proposal in May 2026, which has now been rejected again, with MoHUA citing that projected travel-time savings do not justify the investment and pointing to discrepancies in traffic projections.

TNPSC Relevance

Metro Rail Policy, Centre-State fiscal relations, and urban transport infrastructure are important topics for TNPSC Group 1 Mains (Infrastructure and Development) and Group 2 General Studies. Aspirants should note the population and cost-benefit criteria under the National Metro Rail Policy, 2017, and the alternative of Bus Rapid Transit Systems (BRTS).

Constitutional / Economic / Scientific Relevance

The episode illustrates Centre-State coordination challenges in approving large urban infrastructure projects and the Union government's increasing preference for cost-effective BRTS solutions in Tier-2 cities under the 2017 policy framework.

Tamil Nadu Relevance

Coimbatore and Madurai are Tamil Nadu's second and third largest urban agglomerations respectively. The rejection affects two of the state's key industrial and cultural hubs, coming after the Union Cabinet's 2024 approval of the Rs 63,246 crore Chennai Metro Phase-II project spanning 119 km.

Key Highlights

• MoHUA has rejected the resubmitted DPRs for Coimbatore (two corridors) and Madurai (one corridor) Metro Rail projects.
• The ministry recommends Bus Rapid Transit Systems (BRTS) as a more cost-effective alternative for both cities.
• Chennai Metro Rail Limited (CMRL) had estimated the Metro would cut an average 7.5-km peak-hour commute by about 8 minutes.
• This is the second rejection after the DPRs were first returned in November 2025 citing the 20-lakh population criterion.
