Transport in Thailand

Transport in Thailand is very different and exciting, with many ways to travel. For long trips, most people take buses. Trains have been used for a long time, especially in the countryside, but new fast train lines are being built.

For short trips, many people ride motorbikes. In big cities like Bangkok and Pattaya, you can find motorcycle taxis. Bangkok also has regular taxis and a busy train system that started in 1999. More train lines are being built.

Cars have become more popular, especially among tourists and wealthier people. Thailand has been building motorways, especially around Bangkok and central Thailand.

Flying inside Thailand has become easier and cheaper since 2010, thanks to budget airlines like Thai Air Asia and Nok Air. In areas with rivers and canals, boats are a common way to get around. You can also find special vehicles like tuk-tuk, shared vans called vanpool, and songthaew. In some rural places, people have even used elephants to travel!

Rail transport

The State Railway of Thailand runs all of Thailand's national rail lines. Krung Thep Aphiwat Central Terminal became the main station for all rail routes in 2023, replacing the older Bangkok Railway Station. Phahonyothin and ICD Lat Krabang are the main places for freight trains.

As of 2025, the State Railway of Thailand had 4,507 km of tracks, mostly meter gauge except for the Airport Link. Most tracks are single, but some important parts around Bangkok have double or triple tracks, with plans to add more. Thailand also has many more highways than rail tracks.

Thailand has rail connections to two neighboring countries. The line to Malaysia uses the same track width, as does the line to Laos across the Mekong River. The line to Cambodia is being rebuilt, while the line to Myanmar is not in use.

Bangkok has long-distance trains and some commuter trains, but not many people use them. The city also has three rapid transit rail systems.

Road transport

Thailand has many roads and highways, totaling about 390,000 kilometers (242,335 miles). In 2017, there were around 37 million vehicles on Thai roads, including over 20 million motorbikes, millions of cars, and many trucks and buses.

Buses are a common way for people to travel long distances in Thailand. There are two main types: buses run by the government and those run by private companies. In Bangkok, there is a good public bus system, and some buses have special lanes to help them move faster.

Thailand is working on building more highways and expressways to help traffic flow better, especially around Bangkok. Many people use motorbikes, and the government is trying to make roads safer.
