The train route from Bangkok to the southern provinces in Thailand is one of the most reliable ways to reach the country’s coastline, allowing travelers to experience its landscapes and local rhythms along the way. This route connects Bangkok to Hua Hin, Chumphon, Surat Thani, Trang, and Hat Yai — and links directly to popular island gateways such as Koh Samui, Koh Phangan, Koh Tao, and Phuket. 

This guide explains the major routes, travel times, and ticket options, and provides useful tips to help you plan your journey smoothly.

Why the Southern Train Route Is Worth Taking

Choosing the southern Thailand train route allows travelers to move steadily from Bangkok into the coastal regions without the stress of airport transfers or long highway travel. The journey passes through agricultural zones, seaside provinces, and southern forests, offering a clear look at how Thailand shifts from central plains to maritime landscapes.

Trains depart from Krung Thep Aphiwat Central Terminal and are operated by the State Railway of Thailand (SRT). Most long-distance trains include sleeper cabins and air-conditioned coaches, making them suitable for both daytime and overnight travel. For travelers interested in a lower-impact travel choice, the train uses less carbon than flying and allows for a more grounded experience of southern Thailand.
