Thai-Chinese High-Speed Rail Project Phase One Surpasses 50% Completion

BANGKOK, February 2026 —Asia's rail infrastructure is experiencing a significant surge in development, with cross-border high-speed rail projects playing a crucial role in enhancing regional connectivity and economic integration. The Thai-Chinese high-speed rail initiative represents a key component of this evolving landscape.

The first phase of the ambitious Thai-Chinese high-speed rail project has reached a significant milestone, with construction progress now exceeding 51.74%. State Railway of Thailand (SRT) acting governor Anan Phonimdaeng reported that two contracts, covering the Klang Dong–Pang Asok and Sikhiu–Kut Chik sections, are fully completed. Construction is actively underway on ten additional contracts, while two others, for the Bang Sue–Don Mueang and Ban Pho–Phra Kaeo sections, are awaiting contract signing.

This progress is vital for Thailand's long-term infrastructure goals, aiming to create a modern, efficient transportation network. The 357.12km section, valued at 256.4 billion baht, will eventually feature five stations: Bua Yai Junction, Ban Phai, Khon Kaen, Udon Thani, and Nong Khai. Bidding and contract finalization are anticipated within the current year, with construction expected to span 48 months, targeting an opening in 2031.

The project underscores a commitment to adhering to strict timelines and maintaining high engineering and safety standards, as emphasized by the SRT. This focus is critical for ensuring the long-term viability and reliability of the network, which is designed to facilitate faster travel and boost economic activity along its route.

As Southeast Asia continues to prioritize high-speed rail development, the Thai-Chinese project's steady advancement reflects a broader regional trend towards enhanced connectivity and integrated transport systems, positioning Thailand as a key hub in the continent's evolving rail network.
