Why in news?

On 11 October 2026 (Sunday), Prime Minister Narendra Modi inaugurated the Poonamallee–Vadapalani stretch of Phase II of the Chennai Metro Rail project in Chennai. On the same day, he inaugurated and laid the foundation stones of highway, railway, port and petroleum projects worth over ₹13,000 crore in Tamil Nadu, and addressed the gathering. Along with Chief Minister C. Joseph Vijay, he travelled by metro from the Porur Bypass station to the Poonamallee Bypass station.

The New Stretch – Key Features

• Length: about 15 km; 11 elevated stations. Cost: about ₹4,900 crore.
• It is part of Phase II's Corridor 4 (Lighthouse–Poonamallee Bypass).
• Its distinctive feature is a 3.7-km double-decker structure.
• It is fitted with advanced signalling designed to support driverless operation in future.
• It connects Chennai's western suburbs with the city centre. From 12 October, regular services run in both directions daily from 7 am to 9 pm.

Phase II – Background

• The Union Cabinet approved Phase II on 3 October 2024.
• Total length 118.9 km, three corridors, 128 stations, estimated cost ₹63,246 crore.
• Corridor 3: Madhavaram–SIPCOT (45.8 km, 50 stations). Corridor 4: Lighthouse–Poonamallee Bypass (26.1 km, 30 stations). Corridor 5: Madhavaram–Sholinganallur (47 km, 48 stations).
• When Phase II is complete, the Chennai Metro network will grow to about 173 km.

Other Projects Launched the Same Day

• National Highways (about ₹3,700 crore): a 36-km four-lane section on NH-744 and the Madurai Ring Road (NH-744A, 30 km) were inaugurated. Foundation stone laid for the Thiruvarur Bypass (NH-83).
• Railways (over ₹750 crore): the Karaikal–Peralam railway line, three rail flyovers in the Coimbatore area, and 5 stations redeveloped under the Amrit Bharat Station Scheme.
• Ports: at Chennai Port, a storage yard, 4 EXIM godowns and an upgraded cruise terminal. 8 projects at V.O. Chidambaranar Port, Thoothukudi. Coal Berth-3 inaugurated at Kamarajar Port.
• Petroleum: foundation stone for a Lube Oil Base Stocks (LOBS) project with a capacity of 2.7 lakh tonnes a year at the CPCL refinery in Manali, Chennai (about ₹1,620 crore).

The State Government's Demands

• Chief Minister Vijay sought early approval for Chennai Metro Phase III, metro services for Coimbatore and Madurai, and an inter-state metro link between Hosur and Bommasandra (Karnataka).
• The demands also included the Chennai–Coimbatore and Chennai–Kanyakumari high-speed rail corridors, release of pending Samagra Shiksha funds, extension of GST compensation, and recognition of Tamil as an official language in Madras High Court proceedings.
• The State government's goal is to make Tamil Nadu a USD 1.5 trillion economy by 2036.

For Prelims – Key Points

• Central laws on metros: the Metro Railways (Construction of Works) Act, 1978; the Metro Railways (Operation and Maintenance) Act, 2002.
• Metro Rail Policy 2017: stresses transit-oriented development (TOD), last-mile connectivity and private participation in new metro projects.
• Chennai Metro Rail Limited (CMRL): a joint venture of the Government of India and the Government of Tamil Nadu. The first section of Phase I (Alandur–Koyambedu) began operations in 2015.
• Kamarajar Port (Ennore): India's first major port registered as a company.
• V.O. Chidambaranar Port (Thoothukudi): named after freedom fighter V.O. Chidambaranar, who founded the Swadeshi Steam Navigation Company in 1906.
• Amrit Bharat Station Scheme: a Ministry of Railways scheme to upgrade railway stations in phases on the basis of long-term master plans.

Tamil Nadu / India Connection

• Five railway stations – Palani, Vellore Cantonment, Ambasamudram, Paramakudi and Namakkal – were inaugurated under the Amrit Bharat scheme.
• Three rail flyovers in the Coimbatore area were dedicated to the nation. The State government has sought the Centre's support for metro projects in Coimbatore and Madurai.

For Mains – Analysis

Significance: Linking the western suburbs with the city centre will cut travel time, road congestion and vehicular pollution. As the Prime Minister noted, metro services that existed in only 5 cities in 2014 now cover 25 cities, and the network has grown from about 250 km to over 1,100 km. The double-decker structure is an innovative answer to the shortage of urban land.

Challenges: High capital cost, inadequate fare revenue, poor last-mile connectivity, land acquisition, Centre–State cost-sharing, and delays in approving new projects (Phase III and the demands for metros in second-tier cities).

Way forward: Integrated ticketing across bus, suburban rail and metro, transit-oriented development (TOD), land value capture financing, and faster approvals in the spirit of cooperative federalism.
