Government buses from Chennai to Trichy leave from the Kilambakkam terminus (KCBT) on GST Road, run by SETC and TNSTC. The road trip of about 335 km takes six to seven hours, and the state fare table puts an ultra deluxe seat at about Rs 335 before tolls and reservation charges.
The numbers
If you are searching for a Chennai to Trichy bus, start at Kilambakkam. The official booking site tnstc.in lists “Chennai Kilambakkam KCBT to Trichy” among its most popular routes, and that is where SETC long-distance coaches and TNSTC services for the south now begin. Private omni buses still pick up across the city, including Koyambedu, Guindy, Tambaram and Perungalathur.
At the Trichy end, most private buses drop at the Central bus stand or Chathiram, while government Chennai services have been routed through the new Panjapur integrated bus terminus since July 2025. The details below come from the Transport Department’s fare table and the booking pages we checked on 31 October 2026.
Where to board the Chennai to Trichy bus
Kilambakkam, formally the Kalaignar Centenary Bus Terminus, sits on GST Road just past Vandalur. Every Trichy-bound SETC coach starts here, including the new Volvo multi-axle AC semi-sleepers that SETC says on its booking site were introduced first to major cities such as Trichy, Madurai and Salem. Buses heading south pick up again along GST Road, so Tambaram and Perungalathur residents can often board without going to the terminus itself; check the boarding point list when you book.
To reach Kilambakkam by MTC, the trunk routes along GST Road help. Route 21G runs from Broadway to Tambaram through Guindy, the airport and Chromepet, and 170A links Madhavaram to Vandalur Zoo via Koyambedu, the airport, Tambaram and Perungalathur, ending a short hop from the terminus. Frequencies on those route pages are averages from MTC data and may be dated, so check live timings in the official app before you set out.
SETC and TNSTC bus classes and fares
Tamil Nadu sets mofussil fares per kilometre, and the rates in the Transport Department’s Policy Note 2025-26 have been in force since 29 January 2018. Air-conditioned and sleeper classes carry a higher “peak” rate and a lower “lean” rate. Applied to the 335 km road distance, the base fares work out as below. Your actual ticket will differ a little because it includes tolls and reservation charges and is calculated on the corporation’s own fare stages.
| Class | Rate per km | Base fare for 335 km (approx.) |
|---|---|---|
| Ultra deluxe | 100 paise | Rs 335 |
| AC seater | 110 (lean) to 130 (peak) paise | Rs 369 to Rs 436 |
| Non-AC sleeper | 135 to 155 paise | Rs 452 to Rs 519 |
| AC sleeper | 180 to 200 paise | Rs 603 to Rs 670 |
Source: Tamil Nadu Transport Department, Policy Note 2025-26, mofussil fare table (rates in force since 29 January 2018). Base fares are simple arithmetic: rate per km multiplied by the route distance listed on redBus; tickets add tolls and reservation charges.
Booking is on tnstc.in, the TNSTC app, or by sending “Hi” on WhatsApp to 9444018898, a channel the booking site itself advertises. The search form has a “Single Lady” option for women travelling alone. The policy note says seats can be reserved up to 90 days ahead and that the toll-free 149 helpline handles complaints for all eight state transport undertakings.

Private omni buses on the route
The private market on this corridor is large. On 31 October 2026, redBus listed fares from about Rs 350 at the low end, with operator journey times between roughly 6 hours 5 minutes and 6 hours 55 minutes. A MakeMyTrip search for a weekday departure on the same day showed mostly AC sleeper (2+1) coaches leaving in the evening, with “from” fares between about Rs 500 and Rs 1,249. Boarding points there included Koyambedu, Porur toll gate, Guindy, Tambaram, Vandalur and Kilambakkam.
It’s often said you have to go all the way to Kilambakkam for any bus to Trichy.
The record shows That applies to government services. Private operators on booking platforms still list pick-ups at Koyambedu, Guindy and Porur, so check the boarding point on your ticket rather than assuming.
Journey time and the road to Trichy
Buses take GST Road out to Chengalpattu and Tindivanam, then the national highway through Villupuram, Ulundurpet and Perambalur, entering Trichy past Samayapuram. From Villupuram onward this is NH 38, which a Lok Sabha answer describes as running from Vellore to Thoothukudi. Night departures are the norm, so most travellers sleep through the drive and arrive before dawn.
Arriving in Trichy: Panjapur, Central and Chathiram
Trichy’s new Panjapur integrated bus terminus began operations on 16 July 2025. The district collector’s schedule, reported by DT Next, counted 317 SETC services to and from Chennai among the long-distance trips handled there, with city buses linking the terminus to Srirangam, Samayapuram and Thuvakudi. A day later, minister K.N. Nehru said the Central and Chathiram stands would also keep operating, DT Next reported, with city buses reaching Panjapur through both. Private buses on booking sites still list Central bus stand and Chathiram as drop points, so check the drop point on your ticket.
