Chennai Mass Rapid Transit System

The Chennai Mass Rapid Transit System (MRTS) is a rapid rail line in Chennai, India, run by Southern Railway, part of Indian Railways. It opened in 1995 and was the first elevated railway line in the country. The system runs from Chennai Beach to Velachery, covering 19.34 km with 18 stations. Most of the line is elevated, with some at-grade sections at the ends, and it runs along the Buckingham Canal near the coast. The MRTS shares the same broad gauge as Chennai’s suburban railways, so trains can, in theory, move between the MRTS and suburban networks.

Trains and fares
- Trains: 9-car electric multiple units (EMUs) powered by 25 kV overhead lines. Coaches are built by the Integral Coach Factory in Chennai. Coaches are not air-conditioned and offer two-class seating (first and second class).
- Ridership and trips: As of 2023, about 100,000 passengers use the MRTS each day. On weekdays, around 70 trains run; Sundays see fewer services. A Beach to Velachery trip takes more than 45 minutes.
- Tickets: One-way fares start around ₹5–₹10 for second class; first-class fares are higher. Monthly and quarterly passes are available, along with shorter tickets for tourists.

What you can see along the route
- Key stations connect with major parts of the city. Beach and Park Town are near central business and historic areas; Velachery is a major southern hub. The line passes near Marina Beach, Chepauk stadium, and areas of IT development along the Old Mahabalipuram Road (OMR).
- The MRTS connects with the wider Chennai Suburban Railway network and is planned to integrate further with the Chennai Metro in the future.

History and status
- Planning and construction: The idea came from transport studies in the 1960s. The first phase (Chennai Beach to Chepauk) opened in 1995, with a extension to Thirumayilai in 1997. The second phase extended to Velachery and was completed by 2007.
- Extensions and delays: A planned extension from Velachery to St. Thomas Mount is under construction, but it has faced delays due to land acquisition and other issues. Other long-term plans for additional lines have been studied but are not yet complete.
- Possible takeover by Chennai Metro: Since 2017, there has been talk of integrating or transferring MRTS operations to Chennai Metro Rail Limited. In 2022, in-principle approval was given for a takeover, but as of mid-2024 it had not been finalized.

Challenges and improvements
- Integration: The MRTS is not yet fully integrated with other city transit systems, making last-mile connections harder.
- Maintenance and facilities: Stations have faced maintenance, security, and facility issues, such as water seepage and limited amenities. There have been calls for better inter-modal links and improved ticketing and station access.
- Infrastructure: While most of the line is elevated, some sections and the canal-rights along the route have raised concerns about maintenance and navigation.

Economics
- Revenue and costs: The MRTS generates revenue, but operating costs are high, leading to losses. Subsidies and fare structures contribute to the financial picture.

In short, the Chennai MRTS is a key elevated rail line linking the city’s northern coastline to its southern suburbs. It offers a fast, direct route through central areas and growing IT hubs but faces challenges in expansion, integration with other transit modes, and financial sustainability.
