Overview of the Chennai Metro Network in 2026
Launched in 2015, the Chennai Metro has rapidly expanded its footprint. The system is a mix of underground and elevated corridors designed to connect key locations, including the airport, major railway stations, bus terminals, and commercial hubs. By 2026, the network is expected to be significantly larger with the progress of Phase II, which will introduce new lines and dramatically improve connectivity to areas previously underserved by rapid transit.
The focus of CMRL has been on creating a passenger-centric system. Stations are equipped with modern amenities like escalators, lifts, and facilities for differently-abled passengers. The integration of technology is evident in its automated ticketing systems, including travel cards and mobile QR code options, which make the entire process of travel efficient and hassle-free. Safety and cleanliness are top priorities, making it a preferred mode of transport for many.
