Since there is no direct train service to Sukhothai from Bangkok, travellers can board the train going to Phitsanulok and from there take the local buses going to Sukhothai.
The Phitsanulok railway station is 59 km from the city of Sukhothai. Trains leave from the Bangkok Railway Station and take about 7 hours to reach.
