Vietnam-based conglomerate THACO has proposed studying and investing in two major rail projects in Ho Chi Minh City Metro Line 2 and the 41.8 km Thu Thiem–Long Thanh railway. The proposals align with the city’s TOD-based urban transport strategy and the National Assembly’s Resolution 188. If approved, the projects would be executed via EPC contracts or direct investment, with research expected to begin immediately and not delay scheduled groundbreakings in late 2025 and 2026.

THACO’s vision includes integrating the two lines into a seamless Ben Thanh–Thu Thiem–Long Thanh corridor, linking two international airports—Tan Son Nhat and Long Thanh. The combined route would span 47.8 km and cost an estimated USD4.7 billion. THACO also pledged to share all research with the city at no cost if not selected. The proposal has been welcomed by city officials and awaits prime ministerial review.
