Thammasat runs two free shuttle lines from Tha Prachan, Monday to Friday. Both leave from in front of the Thammasat University Auditorium (หน้าหอประชุมมหาวิทยาลัยธรรมศาสตร์). There is no service on Saturdays or Sundays.
New shuttle timetables from 1 October 2026
From Thursday 1 October 2026 the Sanam Chai and Pinklao lines each run with 1 bus, so there are fewer departures. Both lines run from 07:00 to 21:30 on weekdays.
If a shuttle time does not suit you, use the M2 shuttle bus from Sanam Luang, or public bus routes 53, 43 or 15.

Delays and live positions
Times are scheduled, not guaranteed
In heavy traffic a bus can run late. A late departure moves to the next scheduled slot and is not cancelled. The timetable and the countdown show the schedule, not where the bus is. Leave a buffer if you have a train to catch or an exam to sit.
The Viabus app shows live bus positions. Its free version is limited. Public buses are on Live bus times. At weekends use the boat, the MRT or ride-hailing, as described in Getting to Tha Prachan.
