Thailand has approved a massive double track railway network to boost tourism and connectivity. Thailand has approved a huge railway expansion programme worth more than 100 billion baht to develop a new double-track railway network in the country’s southern region, which will improve tourism, passenger traffic and cross-border connectivity with Malaysia.

The major infrastructure investment will transform the existing railway corridor between Chumphon and Padang Besar on the Malaysia border, creating a faster and more reliable transport system for travellers exploring southern Thailand. The project is expected to strengthen connections between major tourism gateways, economic zones and border destinations while supporting future growth in passenger and freight services.

The approved development forms part of Thailand’s wider Double-Track Railway Expansion Programme, designed to modernise the country’s rail network and improve travel efficiency by replacing sections of single-track operations with advanced dual-track infrastructure.

Thailand’s New Railway Investment Set to Transform Southern Tourism Travel

The Over 100 Billion Baht Double-Track Railway Network has been approved to upgrade key southern railway routes connecting important destinations and transport hubs. The combined investment of approximately 106.8 billion baht will support railway improvements across the southern corridor, creating stronger links between tourism destinations, urban centres and the Malaysian border.

The upgraded network is expected to create smoother journeys for domestic and international travellers visiting southern Thailand. The region is recognised for its beaches, islands, cultural attractions and border tourism experiences, and improved rail connectivity is expected to make these destinations easier to access.

The railway expansion will connect major locations including Chumphon, Surat Thani, Hat Yai and Padang Besar, improving movement between tourism gateways and strengthening Thailand’s position as a connected travel destination in Southeast Asia.

Surat Thani, one of southern Thailand’s most important tourism entry points, provides access to globally recognised island destinations including Koh Samui, Koh Phangan and Koh Tao. Hat Yai serves as a major transport and commercial hub, connecting travellers towards Malaysia and other southern provinces.

By increasing railway capacity and improving operational efficiency, the project is expected to encourage more travellers to explore southern destinations while supporting sustainable tourism mobility.

Three Major Double-Track Railway Projects Approved Under Thailand’s Expansion Plan

The approved Over 100 Billion Baht Double-Track Railway Network includes three major southern railway projects designed to improve tourism connectivity, passenger movement and cross-border transportation between Thailand and Malaysia.

The key projects include:

• Chumphon–Surat Thani Double-Track Railway Project
  • Approved investment: 36.9 billion baht
  • Construction period: Seven years from fiscal year 2026
  • The project will improve railway access between Chumphon and Surat Thani, strengthening connections to southern tourism gateways and popular island destinations.
• Surat Thani–Hat Yai Junction Double-Track Railway Project
  • Approved investment: 61.5 billion baht
  • Construction period: Eight years
  • As the largest section of the programme, this route will enhance railway capacity between major southern cities while supporting tourism growth, passenger services and regional economic activity.
• Hat Yai Junction–Padang Besar Double-Track Railway Project
  • Approved investment: 8.37 billion baht
  • Construction period: Six years
  • The project will strengthen Thailand’s railway connection with Malaysia through Padang Besar, improving cross-border travel opportunities and supporting ASEAN connectivity.

Together, these projects will create a continuous double-track railway corridor from Chumphon to Padang Besar, allowing trains travelling in opposite directions to operate more efficiently while reducing delays and improving passenger convenience.

Double-Track Railway Network to Improve Passenger Experience and Travel Efficiency

The shift from single-track railway operations to a Double-Track Railway Network is expected to significantly improve Thailand’s travel infrastructure.

Under the existing single-track system, trains travelling in opposite directions often need to stop at stations or passing points before continuing their journeys. The new double-track infrastructure will allow trains moving in different directions to operate more smoothly without extended waiting periods.

The railway upgrade is expected to deliver several benefits:

• Faster railway journeys for travellers
• More frequent passenger services
• Improved travel reliability
• Increased freight transportation capacity
• Enhanced railway safety standards

For tourists, the improved railway system could provide a more convenient alternative for travelling between southern cities, coastal areas and border destinations.

Thailand Strengthens Malaysia Connectivity Through Padang Besar Rail Link

The Hat Yai Junction–Padang Besar railway section will play a significant role in improving Thailand’s international transport connections.

The route will link Thailand’s railway system with Malaysia through the Padang Besar border crossing, creating stronger opportunities for cross-border tourism and regional travel.

The improved railway connection is expected to benefit travellers moving between Thailand and Malaysia by offering more efficient transport options. It will also support Thailand’s wider goal of strengthening ASEAN connectivity through improved infrastructure links.

The project could further enhance tourism cooperation between neighbouring countries while encouraging more visitors to explore destinations across southern Thailand.

Budget Increase Driven by Infrastructure Improvements

The approved budgets for some railway sections increased compared with previous proposals due to additional infrastructure requirements.

The higher costs were linked to updated engineering designs, improved flood prevention systems, upgraded level crossings, rising construction material prices, increased diesel costs, land acquisition requirements and compensation expenses.

The supervision fee was also adjusted from 2.25% to 2.75% of construction costs, contributing to the revised project investment.

These improvements are expected to ensure the railway system meets modern safety standards and provides long-term operational benefits.

Hat Yai to Songkhla Railway Section Delayed Over Land Issues

The proposed Hat Yai Junction–Songkhla railway section has not yet received final approval due to land-related challenges.

The planned route covers approximately 29.22 kilometres with an estimated investment of 15.9 billion baht.

The project will remain under consideration until land occupation issues are resolved. Once completed, the connection could further improve railway access and tourism mobility in southern Thailand.

Thailand Plans More Railway Expansion Across Other Regions

Alongside the southern railway projects, Thailand has also approved three additional railway routes in principle.

The proposed projects include:

• Pak Nam Pho–Den Chai railway route
• Den Chai–Chiang Mai railway route
• Thanon Chira Junction–Ubon Ratchathani railway route

The State Railway of Thailand will conduct feasibility studies and prepare business plans before further development decisions are made.

The government is also accelerating studies for a future railway connection between Hat Yai Junction and Sungai Kolok, which could further improve transport access in southern Thailand.

Government Investment Supports Thailand’s Future Tourism Connectivity

The full cost of the southern railway expansion will be supported by the Thai government through annual budget allocations. Domestic loans arranged through government financial mechanisms will also support project implementation.

The State Railway of Thailand is expected to begin contract signing activities in 2027, with completion of the railway expansion targeted for 2033.

Thailand has approved a massive double-track railway network to support tourism and cross-border connections. The over 100-billion-baht project will enhance travel efficiency, link southern destinations to Malaysia, and boost regional tourism growth.

The Thailand Double-Track Railway Network is set to become a significant milestone towards enhanced tourism mobility, regional connectivity and cross-border mobility. By linking the major southern destinations with more efficient railway infrastructure the project is set to create new tourism opportunities while enhancing Thailand’s status as a leading travel hub in Southeast Asia.
