Inauguration and Commencement (2015)

The Green Line officially joined Chennai's metro network on June 29, 2015, marking a significant milestone in the city's public transportation history. With its inauguration, Chennai became the second Indian city, after Delhi, to introduce a modern rapid transit system.

The initial stretch, covering 22 kilometres, served the south–northeast corridor of the city, connecting vital locations and easing the burden on existing transport infrastructure.

Chennai Metro Rail Limited (CMRL) - Driving Force Behind the Green Line

The planning, construction, and operation of the Chennai Metro, including the Green Line, are under the purview of Chennai Metro Rail Limited (CMRL). CMRL, a joint venture between the Government of India and the Government of Tamil Nadu, has been instrumental in steering the project from conception to reality.

Infrastructure and Technology

Unlike the Mass Rapid Transit System (MRTS), the Green Line opted for standard gauge (1435 mm) tracks. Electrification was achieved through 25 kV AC via overhead wires, ensuring an efficient and eco-friendly mode of transport. The choice of four-coach trains, operating at a maximum speed of 80 km/h, reflected a commitment to providing swift and reliable commuting options.

Strategic Route Planning

The Green Line's route planning was a result of meticulous urban planning to ensure optimal connectivity. Stretching from St. Thomas Mount to Chennai Central, the line strategically passed through key areas, including commercial hubs, educational institutions, and residential neighbourhoods. The placement of stations aimed to enhance accessibility for residents and commuters.

Incorporation of Interchange Stations

Interchange stations play a vital role in facilitating smooth transfers between different metro lines. The Green Line boasts two interchange stations - MGR Central (Chennai Central) and Arignar Anna Alandur. These strategic interchanges enhance the overall efficiency of the metro network, allowing passengers to seamlessly switch between different corridors.

Continuous Expansion and Future Developments

The journey of the Chennai Metro Green Line didn't conclude with its inauguration. The metro system has been dynamic, with plans for continuous expansion and integration with upcoming corridors. As of the latest updates, Chennai Metro Rail Limited (CMRL) has been actively involved in feasibility studies for future projects, showcasing the city's commitment to evolving and embracing innovative transportation solutions.
