Tamil Nadu Finance Minister Wilson confirms Hosur to Karnataka border metro plan

The Story in Brief

Tamil Nadu Finance Minister N Marie Wilson confirmed on 5 August that the state government is pursuing a metro rail link from Hosur in Krishnagiri district to Bommasandra in Karnataka, working with both the central and Karnataka governments. Announced during his budget address, the proposal describes a 23 km corridor with 12 stations, of which 12 km would lie in Karnataka and 11 km in Tamil Nadu. A feasibility study reached advanced stages last year and the project aims to improve connectivity for thousands of daily commuters between the industrial town of Hosur, home to companies such as TVS, Ashok Leyland and Titan, and Bengaluru’s Bommasandra area.

The plan comes despite the Bangalore Metro Rail Corporation Limited rejecting the proposal earlier this year on technical grounds. BMRCL said a direct connection is not technically feasible because Chennai Metro Rail Limited has proposed a 25 kilovolt AC overhead traction system while Namma Metro operates on a 750 volt DC third rail system. Tamil Nadu is seeking early central approval and has suggested that, if construction proceeds up to the Karnataka border, two separate stations could be linked by a foot overbridge at Attibele. The announcement also coincided with updates on Chennai Metro Phase II – a 118.9 km project estimated at Rs 63,246 crore, with a 14.64 km stretch from Poonamallee Bypass to Porur Junction due for commissioning shortly – and pursuit of other corridors including Chennai Airport-Kilambakkam, Avadi and Sriperumbudur.

The Indian Opinion

The report presents two clear, factual strands: a state proposal arguing economic and commuter benefits, and a technical assessment from BMRCL that identifies incompatible electrical systems. Readers should note that the technical issue is not a matter of preference but of engineering compatibility between 25 kV AC overhead traction and 750 V DC third rail systems. Suggestions such as linking separate stations by a foot overbridge would preserve a physical connection but may reduce operational convenience and journey time benefits. The article does not give details on timelines, funding allocations for the Hosur-Bommasandra link, or formal responses from Karnataka and the central government, so the project’s realisation remains uncertain until those approvals and technical resolutions are publicly documented.
