Chennai Metro is the rapid transit system serving Tamil Nadu’s capital, run by Chennai Metro Rail Limited (CMRL). Phase 1 has been carrying passengers since 2015, and a much larger Phase 2 is under construction that will roughly triple the network and reach parts of the city the first phase never touched.
The network
Phase 1 covers about 54 km across two corridors, the Blue Line and the Green Line, mixing underground stretches through the crowded core with elevated sections further out. The lines meet at Chennai Central and connect with the suburban rail and MRTS, so riders can move between systems at a single point. Phase 2 adds three new corridors of roughly 118 km, a big step up in scale.
Operator and what comes next
CMRL builds and runs the metro. Its near-term work is Phase 2, where civil construction, tunnelling, stations and systems are progressing corridor by corridor. Contract awards, viaduct milestones and station updates keep coming as the phase advances toward opening.
