Chennai Metro Rail Phase-II, approved by the Union Cabinet in October 2024 on the Ministry of Housing and Urban Affairs' proposal, adds three corridors, 118.9 km and 128 stations at Rs 63,246 crore, due by 2027. The Prime Minister opened its first stretch, about 15 km and 11 stations from Poonamallee Bypass towards Vadapalani, on 11 October 2026.

Why it matters

A commuter in Chennai's western suburbs, around Poonamallee or Porur, can now take a train that comes every 10 minutes at peak hours instead of sitting in road traffic, and the line is designed to meet Phase-I at Vadapalani. The Cabinet expects Phase-II to ease congestion, cut carbon emissions compared with fossil-fuel transport and bring jobs within easier reach, such as in the IT hub at Sholinganallur. The price is steep: Rs 63,246 crore for 118.9 km, or about Rs 532 crore a km. The larger question for every growing Indian city is whether ridership, feeder links and fares let such lines repay that cost.
