The Thai government is progressing with plans for six new double-track rail routes, with a combined length of 1,312 kilometers and an estimated cost of 280 billion baht. These projects are aimed at improving transportation efficiency and cross-border connectivity, particularly with Malaysia. The routes are currently awaiting approval from the National Economic and Social Development Board before being submitted to the Cabinet for final authorization.
One of the key projects is a 216-kilometer rail line between Hat Yai and Su-ngai Kolok in southern Thailand, estimated to cost 34.59 billion baht. This line will help connect Thailand with Malaysia and include 27 stations, 8 stops, and two freight terminals. It aims to enhance trade, tourism, and economic development in the southern border provinces.
The State Railway of Thailand (SRT) has been assigned to conduct a feasibility study for the Hat Yai to Su-ngai Kolok route, with a budget of 80 million baht for the study, which is set to be completed by 2026. Following that, detailed design work, environmental impact assessments, and Cabinet approval are planned in the years to follow. Construction is expected to begin in 2027, with completion targeted for 2032.
Additionally, Phase 2 of the double-track railway project includes six more routes, such as the 281-kilometer Paknampho to Den Chai section and the 168-kilometer Chumphon to Surat Thani route. These projects aim to improve domestic rail connections and enhance regional integration.
The proposed railway expansion, once approved, will provide a significant boost to Thailand’s transportation infrastructure, regional trade, and economic growth.
