The State Railway of Thailand (SRT) has signed a memorandum of understanding (MOU) with the Engineering Institute of Thailand (EIT) and the Rail Technology Research and Development Agency (RTRDA) to support Phase 2 of the Thai–China high-speed rail project. The agreement, valid from November 11, 2025, to November 10, 2030, commits to maximising the use of domestically produced construction materials in line with the Transport Ministry’s “Thailand First” policy, while ensuring quality, efficiency, and safety.
Phase 2 covers the 357.12 km Nakhon Ratchasima–Nong Khai section, including five stations: Bua Yai, Ban Phai, Khon Kaen, Udon Thani, and Nong Khai. The MOU establishes collaboration across SRT, EIT, and RTRDA in academic cooperation, research, planning, and development of civil engineering standards. Supplementary civil-works requirements beyond standard Chinese high-speed rail specifications are included to guarantee construction quality and efficiency while stimulating local industry.
The Transport Ministry approved Phase 2 on February 4, 2025, enabling land acquisition, asset compensation, and civil works within the THB341.351 billion budget. SRT plans to issue tender documents in 2026 and begin construction the same year, with service expected by 2031. This initiative aims to strengthen Thailand’s domestic engineering sector and support the country’s position as an ASEAN transport hub.
