The Thailand-China high-speed rail project, connecting Bangkok to Nakhon Ratchasima, is facing significant delays. As of early 2025, work on the rail system has made little progress, falling far behind schedule. The project, managed by China Railway International and China Railway Design Corporation, includes the installation of rail systems, electrical and mechanical works, and the procurement of trains.
Overall progress stands at less than half of what was planned. While two contracts have been completed, most others are still under construction or awaiting finalization. The production of trains is set to begin soon, with test runs planned by 2027 and full service expected by 2028.
The high-speed trains are expected to reach speeds of up to 300 km/h, although they will operate at a practical speed of 250 km/h. Six trainsets will be provided, each with about 560 seats and no standing passengers.
Delays in the construction phase have been caused by issues with land acquisition and slow payments to contractors. Despite these challenges, authorities are hopeful that the revised timeline can still be met.
