If you still renew your suburban season ticket on the UTS app, that route has closed. The Ministry of Railways shut UTS booking on 1 March 2026 and moved unreserved, platform and season tickets to the RailOne app, All India Radio reported. Register on RailOne with the same mobile number and your R-Wallet balance moves across automatically.
The trains themselves have changed less. Chennai’s suburban network still rests on three lines out of Chennai Beach and Chennai Central, with an AC local now on the southern line and another planned for the west. Here is how the network is laid out and how to buy a pass today.
The three suburban corridors
Southern Railway’s Chennai Division groups its electric multiple unit (EMU) services into sections, which its press notices list as Central–Arakkonam, Central–Chengalpattu and the north line towards Gummidipoondi and Sullurupeta, along with Chennai Beach services.
- South line, Beach–Tambaram–Chengalpattu. The busiest corridor, through Egmore, Mambalam, Guindy, St Thomas Mount, Tirusulam (for the airport), Pallavaram, Chromepet and Tambaram. Some trains continue to Arakkonam via Kanchipuram and Tirumalpur.
- West line, Central–Arakkonam. Through Ambattur, Avadi, Tiruninravur and Tiruvallur, with some trains starting from Beach.
- North line, Central/Beach–Gummidipoondi. Up the northern coastal suburbs to Gummidipoondi, with some services running across the Andhra Pradesh border to Sullurupeta.
On holidays the division often switches to the Sunday timetable on all sections, as it did for Vinayagar Chathurthi in 2025, so check notices before a festival day.
Timings on the south line after 1 June 2026
A revised timetable for the Beach–Tambaram–Chengalpattu corridor took effect on 1 June 2026. The number of trains did not change, DT Next reported, but several were retimed:
- 106 services in each direction on weekdays and 97 on Sundays.
- Early departures from Beach between 4.10 am and 7 am moved about five minutes earlier.
- Midday and afternoon trains such as 40047, 40053, 40055 and 40057 were pushed later.
- The last departure from Beach, train 40091, now leaves at 11.59 pm instead of 11.30 pm.
AC locals: what runs and what is coming
Chennai’s first air-conditioned EMU started on 19 April 2025. According to the Southern Railway notice, it runs Beach–Chengalpattu on the main line at 7 am and 3.45 pm (returning from Chengalpattu at 9 am and 5.45 pm, except Sundays), plus a suburban-line pair between Tambaram and Beach. The coaches have automatic doors, CCTV and passenger information displays.
A second AC service between Central and Arakkonam, stopping at places like Ambattur, Avadi and Tiruvallur, was drafted with office commuters in mind and sent to the Railway Board in September 2026, Deccan Chronicle reported. A spare AC rake has been handed over by ICF Perambur. Check the division’s notices for a start date before planning around it.
Season tickets on RailOne
RailOne combines what used to be spread across UTS and IRCTC: reserved and unreserved tickets, platform tickets, season tickets, PNR status and live running. Existing UTS or IRCTC logins work.
- Install RailOne and log in with the mobile number you used on UTS.
- Choose the unreserved or season ticket option, and enter your from and to stations and the class.
- Pick the validity period offered and pay by UPI, card, net banking or R-Wallet.
- Carry your phone with the ticket and the ID card linked to the pass for checks.
Digital payment brings a saving. The railways extended a 3% discount on unreserved tickets booked on RailOne with UPI, cards or net banking until 31 March 2027, and a 3% cashback on R-Wallet top-ups, DT Next reported. Whether the discount applies to season tickets was not stated, so check the price shown at checkout.
If you prefer the counter, all Chennai Division booking windows accept UPI QR payments for unreserved and season tickets, according to a Southern Railway notice.
Practical tips for daily riders
- Check the coach markings before boarding in the peak. Travelling in a higher class than your ticket can bring a penalty during checks.
- During the monsoon, low-lying stretches can see trains slowed or short-terminated. The division posts changes on its press release page and on social media.
- Keep your season ticket’s ID card handy. A digital pass on RailOne still needs the matching ID during checks.
