Chennai’s metro network is set to get a significant boost with the approval of Phase II, adding 118.9 km of new lines and 128 stations. This ambitious project, expected to be completed by 2027, will connect key areas of the city, improve connectivity, reduce traffic congestion, and contribute to Chennai’s sustainable growth.
Chennai Metro Rail (CMRL) is planning to develop commercial properties around its Phase-2 stations in eight locations to generate revenue and integrate transportation with urban development. The project will involve building shopping complexes, office spaces, and pedestrian subways, with some properties being developed jointly with the Metropolitan Transport Corporation (MTC).
The Poonamallee depot, which will service driverless trains on the planned phase-2 extension line to Parandur airport, has received a major boost with the opening of a substation to provide power for daily operations. The depot is expected to be operational by the end of 2025, coinciding with the launch of the first stretch of the phase-2 extension.
Chennai Metro Rail Limited (CMRL) has significantly reduced the size of underground stations in its phase-2 project, aiming to save over ₹2,000 crore in project cost. This was achieved by optimizing the tunnel ventilation system, reducing the number of exhaust fans from eight to two, and redesigning the layout of the stations. Despite the smaller size, the new system ensures safety during emergencies and meets international standards.
Chennai Metro Rail Limited (CMRL) is constructing a 3.75km double-decker elevated metro line between Alwarthirunagar and Alapakkam, offering Madhavaram residents easy access to core city areas. This innovative line, featuring four stations and interchange facilities, will enhance connectivity between corridors 4 and 5, expected to be operational by mid-2026.
Technical difficulties on the blue line of the Chennai metro have caused service disruptions between the Meenambakkam and Airport metro stations. Passengers are advised to switch trains at the Arignar Anna Alandur metro station on Wednesday. The issue is being addressed by the authorities, who apologize for any inconvenience caused.
