Thailand's first phase high-speed rail project (Bangkok-Korat, 250.77 km) is 34.5% behind schedule despite reaching 55.98% completion. Deputy Transport Minister Siripongse has ordered accelerated work to meet the 2573 (2030) finish target, with system testing to begin in 2574. Critical focus is resolving contract disputes on the three-airport connecting segment (Don Muang–Bang Sue). This major infrastructure project affects construction SMEs, logistics providers, and real-estate development along the corridor.
