Dakshineswar ↔ Kavi Subhash
The Blue Line (Line 1) is the original Kolkata Metro and the first metro line ever built in India, opened on 24 October 1984. It runs north–south for 31.4 km between Dakshineswar and Kavi Subhash (New Garia) — currently trains terminate at Shahid Khudiram — forming the backbone of the city’s rapid transit network.
The line threads through the dense heart of Kolkata — largely underground beneath Chowringhee and the central business district, and elevated towards both terminals. It links the Dakshineswar Kali Temple in the north with the southern suburbs around New Garia.
The Blue Line interchanges with the Green Line at Esplanade and the Yellow Line at Noapara, and was built to meet the Orange Line at Kavi Subhash. Since 28 July 2025 the Blue Line platforms at Kavi Subhash have been closed to passengers because of structural damage: Blue Line trains terminate at Shahid Khudiram, and the Blue ↔ Orange interchange at Kavi Subhash cannot be used. No reopening date had been announced as of September 2026. It is operated by Metro Railway, Kolkata, a zone of Indian Railways — the only metro in India run directly by the national railway.
