- Rapid / Express Trains: Other options include Train No. 109 (departs at 02:15 PM) or overnight trains if you prefer to arrive at dawn.
Summary
- Travel Time: Approximately 4 hours 20 minutes to 6 hours (depending on the train type).
- Starting Fares: Starts at around 230 THB for a 3rd-class fan seat up to 1,000+ THB for a 1st-class air-conditioned sleeper berth.
- Getting to the Venue: From the railway station to Naresuan University, you can take a taxi for about 200 THB.
🚌 By Bus
This is a popular choice if you are not in a rush and want to save on travel costs. You can board the buses at the Bangkok Bus Terminal Chatuchak (Mochit 2).
Popular Bus Companies
- Phitsanulok Yanyont Tour (พิษณุโลกยานยนต์ทัวร์): The most popular choice with frequent departures throughout the day and comfortable VIP buses. Note: This bus route usually passes the university. You can ask the driver to let you off directly in front of Naresuan University.
- Sukhothai Wintour: Offers good service with many daily rounds.
- The Transport Co., Ltd. (999): Highly recommended for their comfortable 24-seat VIP late-night buses.
