Thailand’s State Railway (SRT) has reported solid progress on its flagship double-track railway project linking Den Chai, Chiang Rai, and Chiang Khong, a strategic northern economic corridor expected to boost regional trade and tourism. As of now, the project is 36.5% complete, outpacing initial targets by nearly 2%.

 

The 323.1-kilometre line, with a total investment of THB 85.3 billion, is set to open by 2028 (B.E. 2571), according to SRT sources. The land expropriation process has reached 98.5% completion, with most landowners already handing over their plots. Only a few pending parcels remain under negotiation with government agencies.

 

To mitigate the impact of future floods, a major challenge in this railway construction, the project team has introduced a three-pronged strategy:

 

1. Immediate Response – Addressing flood-related emergencies as soon as they arise.

 

2. Design Adjustments – Revising construction plans to reflect the actual terrain and environmental conditions.

 

3. Forecasting and Prevention – Preparing in advance for future flood risks, particularly during dry-season construction periods.

 

Notably, much of the line will run on elevated structures or bridges, which is expected to significantly reduce flood vulnerability in the coming year.

 

Upon completion, the railway is expected to serve as a vital link between Thailand and neighbouring countries, unlocking new border trade opportunities in the North and enhancing the nation’s export capacity. The line will not only strengthen logistics and lower transportation costs but also support Thailand’s broader strategy of developing national infrastructure to sustainably stimulate the economy.

 

Scenically, the Den Chai–Chiang Khong route promises a captivating journey through mountainous terrain, interspersed with tunnels and elevated bridges. The line is anticipated to become a tourist attraction in its own right, drawing both domestic and international visitors, and revitalising existing tourism hubs along the route. The project is also expected to spur the development of new tourist sites and bring increased income to local communities.

I live on its route between Chiang Rai and Chiang Khong. They are certainly getting on with it. I look forward to it opening.

Could the same happen with Rama II road - speed of construction?
