Chennai Metro Overview
Chennai Metro is Tamil Nadu's rapid transit network, operated by Chennai Metro Rail Limited (CMRL), a joint venture of the Government of India and the Government of Tamil Nadu formed in December 2007. Phase I runs 41 Chennai Metro stations across 2 colour-coded lines spanning about 54.65 km, with trains operating daily from roughly 5:00 AM to 11:00 PM.
The Blue Line (Wimco Nagar Depot–Chennai International Airport, 26 stations, 32.65 km) and Green Line (Puratchi Thalaivar Dr. M.G. Ramachandran Central–St. Thomas Mount, 17 stations, 22.00 km) meet at two interchange stations: Puratchi Thalaivar Dr. M.G. Ramachandran Central, next to Chennai Central railway station, and Arignar Anna Alandur in the south. Together the two lines connect Chennai International Airport and the southern IT corridor around Guindy to the historic core around Chennai Central, Egmore, and Anna Nagar, with Blue Line trains extending north to Tiruvottriyur and Wimco Nagar.
Chennai Metro fare is zone-based, rising with distance, and the Singara Chennai Card (Chennai's National Shared Mobility Card) gives a 20% discount over QR-code single-journey tickets. Peak-hour trains on busy stretches like Airport–city centre run as often as every 3 to 6 minutes. The CMRL helpline is 1860-425-1515. MetroYatra provides station-wise Chennai Metro train timings, route map, fare calculator, and platform details for all 41 stations.

Chennai Metro Flags Off India's First Anti-Drag Door Safety System on a Phase 1 Train
Chennai Metro Rail Limited (CMRL) flagged off its first train fitted with an anti-drag door safety system on May 17, 2026, marking the first deployment of the technology on an Indian metro network. The system senses abnormal pulling force on the automatic sliding doors if clothing gets caught while closing, then triggers automatic braking and reopens the door.
CMRL plans to retrofit the remaining 51 trains of its Phase 1 fleet of 52 trainsets, which run on both the Blue and Green lines.
Chennai Metro Blue Line Cuts Peak-Hour Wait to 3 Minutes on Alandur-Washermenpet Stretch
Chennai Metro Rail Limited (CMRL) increased train frequency on the Blue Line from January 7, 2026, citing steadily rising passenger footfall on the corridor. During peak hours (8 am-11 am and 5 pm-8 pm), trains now run every 3 minutes between Alandur and Washermenpet, the busiest stretch, and every 6 minutes elsewhere.
CMRL said the additional services are meant to cut waiting time and ease congestion during high-demand hours.
Chennai Metro Green Line Runs Reduced Frequency for 5 Days to Allow Phase 2 Work at Vadapalani
Chennai Metro Rail Limited made temporary changes to Green Line services between September 15 and 19, 2025, to allow Phase 2 construction work above Vadapalani metro station to proceed. Between 5 am and 6 am, trains ran every 14 minutes on the St Thomas Mount-Ashok Nagar and Airport-Ashok Nagar stretches.
No trains ran between Koyambedu and Ashok Nagar during that hour; CMRL ran dedicated feeder buses every 10 minutes instead. Regular schedules resumed after 6 am each day.
Chennai Metro Crosses 1 Crore Monthly Ridership for the First Time in July 2025
Chennai Metro Rail Limited (CMRL) crossed 1 crore monthly passengers for the first time in July 2025, carrying 1,03,78,835 riders over the month, up 11.6 lakh from June's nearly 92 lakh trips. A new single-day record was set on July 4, 2025, when 3,74,948 commuters used the metro.
CMRL credited the jump to higher service frequency, growing digital ticketing adoption, and improved last-mile connectivity.
Chennai Metro Retires CMRL Travel Card, Shifts All Riders to NCMC Singara Chennai Card
Chennai Metro Rail Limited (CMRL) announced on July 21, 2025 that it would switch commuters completely from the CMRL Travel Card to the Singara Chennai National Common Mobility Card (NCMC). Top-ups on the existing card stopped at all 41 metro stations from August 1, 2025.
Passengers can keep using their travel card until its balance runs out; once it drops below Rs 50, the card must be surrendered at a ticketing counter for a free Singara Chennai Card, with the deposit and balance transferred over.
Chennai Metro Blue Line Gets Nod for 15.46-KM Airport-Kilambakkam Extension, Rs 9,335 Crore

The 15.46-km fully elevated corridor will run along GST Road through Pallavaram, Chrompet, Tambaram, Perungalathur and Vandalur, adding 13 new stations.
