Coimbatore Metro DPR Rejected: The Full Story

Coimbatore's long-awaited metro rail project has hit another roadblock. The Union government has rejected the proposed metro rail projects for Madurai and Coimbatore for the second time, citing inadequate population, low projected ridership and limited travel-time savings. This came after an earlier setback in November 2025, when Tamil Nadu submitted the comprehensive mobility plans and alternative analysis reports for the Coimbatore and Madurai metro projects in December 2024, and on 14 November the Union ministry of housing and urban affairs returned the DPRs stating that Coimbatore's population, as per the 2011 Census, stands at 15.84 lakh, while Madurai's is less than 15 lakh.

The numbers involved are substantial. Tamil Nadu had proposed a Rs 11,360 crore metro network for Madurai and a Rs 10,740 crore project for Coimbatore, with the Coimbatore proposal envisaging a 39-km elevated corridor, while the Madurai plan comprised a 31.93-km network featuring both elevated and underground sections. The Ministry of Housing and Urban Affairs (MoHUA) has been firm on its reasoning. In its communication, MoHUA said the Detailed Project Reports submitted by Chennai Metro Rail Limited did not adequately establish the need for metro rail systems in either city, and the proposals failed to satisfy key parameters laid down under the Metro Rail Policy, 2017. Adding to the friction, the ministry also rejected the state's reliance on projected population estimates for 2022, stating that assessments should be based on the officially available 2011 Census data.

Instead of a metro, the Centre has pointed Tamil Nadu toward a different solution. Instead of investing in metro systems, the Centre advised the state to strengthen bus-based public transport, describing it as a more practical and cost-effective solution for the two cities at present. Metro sector officials also see a technical path forward: with updated population and travel-demand studies, realistic ridership modelling, flexible corridor design, and phased implementation, the DPRs can be revised and resubmitted, and if concrete data and realistic assumptions are used, the Centre's objections may be addressed.

The decision has triggered a sharp political reaction. Tamil Nadu Chief Minister MK Stalin called the move unfair, arguing that the grounds on which the DPRs were returned — both cities do not have a population of 20 lakh as per the National Metro Rail Policy, 2017 — were 'flimsy', while asking why Madurai and Coimbatore were overlooked when the Union government had approved metro networks for tier-II cities with less than 20 lakh population in BJP-ruled States. He specifically pointed to cities like Indore whose population is less than 20 lakh but which have been granted metro rail networks. The DMK escalated the issue further, with the party planning to seek the personal intervention of Prime Minister Narendra Modi in approving metro networks to Madurai and Coimbatore, while a resolution recalled that projects with the same population criterion were approved for cities like Agra.

On the ground, the DMK translated the political messaging into street action. The DMK and its allies held a demonstration in Coimbatore condemning the Centre's decision to return the DPRs. The BJP hit back hard, with state leader K Annamalai accusing the ruling party of distorting facts. He said the DMK was 'playing petty politics' by claiming the Centre had rejected the DPRs when MoHUA had only returned them for corrections, and responded to the Chief Minister's claim of a 'political vendetta' by posting the entire MoHUA letter online. Annamalai's counter-offer was direct: 'Fix the mistakes, resubmit properly, and the Centre will approve — just as it has sanctioned ₹1.5 lakh crore worth of railway projects for Tamil Nadu under Prime Minister Modi.'

Importantly, this isn't necessarily a closed chapter. Officials involved in the process have signalled the process can still move forward. Officials from Chennai Metro Rail Limited indicated that the correspondence should not be seen as a final rejection, confirming that revised versions of the DPRs would be prepared and resubmitted after consultations with the state government and central agencies. There is also a precedent for eventual approval after delay: the Union government did not approve Phase-II of the Chennai Metro for about five years despite an in-principle approval in 2019, with the DMK government building the network using its own funds until the BJP-led Union government finally gave its seal of approval in late 2024.

For homebuyers and investors watching Coimbatore, the metro delay is a reminder that the city's growth story is being written on multiple fronts — not just rail connectivity. Coimbatore continues to draw developer interest on the back of its manufacturing base, IT corridors and expanding social infrastructure, and major national players are entering the market even as this transit debate plays out. Whether the metro eventually gets a green light or the city leans on upgraded bus and BRTS networks, the underlying demand for well-planned, well-connected homes in Coimbatore's growth corridors remains intact, and buyers evaluating projects here would do well to track both the transit roadmap and the credibility of the developers building around it.
