Kochi Metro is Kerala's rapid transit network, operated by Kochi Metro Rail Limited (KMRL), a central-state joint venture. The Blue Line runs 25.61 km with 25 operational Kochi Metro stations between Aluva and Tripunithura, mostly elevated, with trains running daily from 6:00 AM to about 10:30 PM at a peak-hour frequency of around 8 minutes.
The line connects Aluva in the north — near Cochin International Airport — to Kalamassery and Cochin University, then through the central business district at Kaloor, Town Hall, and MG Road, continuing via Ernakulam South and Vyttila to terminate at Tripunithura in the south. A Phase 2 extension from JLN Stadium to InfoPark and Kakkanad, adding 11 more stations, was under construction in 2026 with a target completion of June-December 2026. Kochi Metro also integrates with Kochi Water Metro ferries at several stations, and does not yet have a rail interchange since only one line is currently open.
Kochi Metro fare is zone-based, from ₹10 for short hops up to ₹60 for the longest journeys, with the Kochi1 Card — also usable on buses and Kochi Water Metro — giving up to a 20% discount over single-journey tickets. For travel assistance, the KMRL helpline is 1800-425-0355. MetroYatra provides station-wise Kochi Metro train timings, platform details, and fare information for every operational station.
