Chennai Local Trains : Routes, Lines, MRTS and Latest Updates
Last updated: 1 August 2026
The Chennai suburban railway is the lifeline of the city, carrying around 2.5 million passengers every day across a network that runs from before 4 in the morning until midnight. Operated by Southern Railway, it is India’s second largest suburban system by route length. This guide covers the lines, the MRTS, fares and passes, and the latest developments including the long-awaited MRTS extension.
Latest Updates
MRTS Finally Reaches St. Thomas Mount
After years of delay, the MRTS extension from Velachery to St. Thomas Mount opened in March 2026. This completes a link that had been pending for well over a decade.
The significance is the interchange. St. Thomas Mount now brings together three rail modes at one location: the suburban line on the Chennai Beach to Chengalpattu section, the MRTS terminus, and the Chennai Metro Green Line. For commuters coming in from the southern suburbs, this opens up connections that previously required a road transfer.
Chennai Capacity to Double by 2030
Southern Railway has announced a programme to double train capacity in Chennai by 2030, with Chennai among 48 cities identified for time-bound capacity expansion. The main elements affecting suburban passengers:
- Chennai Egmore redevelopment, with airport-style passenger separation, two AC terminal buildings, 44 lifts, 31 escalators and a 14,000 square metre concourse.
- Tambaram station gets nine lifts and better integration for suburban services.
- A new Perambur terminal, costing around Rs 342 crore with seven platforms, to relieve pressure on Central and Egmore.
- The Chennai Beach to Egmore fourth line has been commissioned, and third and fourth lines between Attipattu and Gummidipundi have been sanctioned.
Before you travel: Renovation work at Egmore and other stations occasionally shifts EMU services to different platforms at short notice. Check the announcement boards on the day, or look up your service on live train running status.
The Chennai Suburban Network
Chennai’s system began in 1931 and has grown into a complex network of more than 300 stations, running roughly 1,000 services a day. Trains are 9-car and 12-car EMUs, with a top speed of about 100 kmph.
| Line | Runs between |
|---|---|
| South Line | Chennai Beach to Tambaram and Chengalpattu, with MEMU services continuing towards Villupuram and Puducherry |
| West Line | Chennai Central to Arakkonam and Tiruttani |
| North Line | Chennai Central towards Gummidipoondi and Sullurpeta |
| MRTS | Chennai Beach to Velachery and St. Thomas Mount |
Additional connecting routes link these corridors, and the network includes what is described as the longest suburban circular route in India.
South Line: The Busiest Corridor
The Chennai Beach to Tambaram stretch is the oldest and busiest section, dating from 1931. Services run at roughly 7 minute intervals during peak hours, stretching to around 20 minutes in the first and last hours of the day. The first EMU leaves Chennai Beach shortly before 4 in the morning and the last runs close to midnight.
Most services terminate at Tambaram, which functions as the main southern hub. Beyond Tambaram, trains continue to Chengalpattu at wider intervals of around 15 minutes at peak.
Chennai MRTS
The Mass Rapid Transit System opened in 1995 and is also run by Southern Railway rather than by Chennai Metro, which confuses many first-time visitors. Key points:
- Runs from Chennai Beach through Velachery to St. Thomas Mount, covering roughly 24 km.
- Largely elevated, following the Buckingham Canal and the coast before turning west towards Velachery.
- Uses 9-coach trains and carries around 200,000 passengers daily.
- Tickets work on the same suburban system, not on Chennai Metro tickets.
Common confusion: Chennai has two separate rail systems in the city. MRTS is run by Southern Railway and uses railway tickets and passes. Chennai Metro is a different operator with its own tickets and smart cards. They meet at points such as St. Thomas Mount, but a ticket for one is not valid on the other. See our Chennai Metro guide.
Major Stations
| Chennai Beach | Terminus for South Line and MRTS services |
| Chennai Central (Puratchi Thalaivar Dr. MGR Central) | Main terminus for West and North Line suburban services and long-distance trains |
| Chennai Egmore | Major suburban and long-distance station, currently being redeveloped |
| Tambaram | Principal southern hub, where most South Line services terminate |
| St. Thomas Mount | Interchange between suburban, MRTS and Metro Green Line |
| Chengalpattu | Southern terminus for suburban services, junction for onward MEMU routes |
Tickets, Fares and Passes
- Suburban fares are distance based and among the cheapest urban transport anywhere in India.
- Both Second Class and First Class tickets are available.
- Season tickets for monthly and longer periods work out far cheaper for daily commuters. See our season tickets guide.
- Buy through the official RailOne app, at station counters, or at ATVMs. See our ATVM guide.
- Paying from your R-Wallet earns a discount on unreserved tickets. See our R-Wallet guide.
Tourist Tickets: Unlimited Travel for Visitors
If you are visiting Chennai and plan to move around a lot, a suburban tourist ticket works out far cheaper than buying single tickets. It allows unlimited travel across the suburban network for a fixed period, and foreign tourists can buy one too.
| Class | Validity | Adult | Child |
|---|---|---|---|
| Second Class | 1 day | Rs 70 | Rs 45 |
| 3 days | Rs 115 | Rs 70 | |
| 5 days | Rs 140 | Rs 80 | |
| First Class | 1 day | Rs 295 | Rs 190 |
| 3 days | Rs 480 | Rs 285 | |
| 5 days | Rs 575 | Rs 330 |
Please confirm at the counter: These rates were set when the Railway Board rationalised suburban tourist ticket fares, and suburban fares get revised from time to time. Check the current price when you buy, rather than budgeting on these figures alone.
Where the Ticket Is Valid
A tourist ticket covers travel on all four Chennai suburban sections:
- Chennai Beach to Tambaram and Chengalpattu
- Chennai Beach or MMC to Tiruvallur
- Chennai Beach or MMC to Gummidipoondi
- The MRTS section, Chennai Beach through Velachery to St. Thomas Mount
Within those sections you can travel from any station to any station, any number of times, for the validity period of your ticket.
Rules to Know
- Validity runs to midnight on the last day, with the exact dates printed on the ticket.
- You can buy one up to 3 days in advance, not counting the first day of validity.
- No concessions apply to tourist tickets.
- No refund on an unused or partly used ticket bought for the same day. A ticket booked in advance can be cancelled before its first day of validity, after a clerkage deduction.
- The validity period cannot be extended under any circumstances, so choose the right duration at the outset.
- Foreign tourists are eligible on the same terms.
Where to Buy
Tourist tickets are issued at suburban booking counters across the Chennai network. Since the UTS app was discontinued in March 2026, use a station counter, and check the official RailOne app for what is available digitally on your section.
Similar tourist tickets exist in other cities. See our guides to the Mumbai local train tourist ticket and the Kolkata local train tourist ticket.
Practical Tips for Chennai Commuters
- Check whether your train is fast or slow. Fast services skip several stops between Tambaram and Beach and save meaningful time in peak hours.
- Peak crowding is heaviest towards the city in the morning and outward in the evening on the South Line.
- Ladies coaches are provided on suburban services, positioned consistently along the rake.
- During the north-east monsoon, roughly October to December, waterlogging can affect services, so allow extra time and check running status before you leave.
- For the airport, use the Metro Blue Line rather than the suburban network, since the suburban line does not serve the terminal directly.
