The Ministry of Public Works and Transport has announced that a feasibility study is in the pipeline for the development of a rail line between Thailand and Vietnam through Cambodia. The proposed cross-border rail line will link Poipet town in Banteay Meanchey province, Siem Reap, Kampong Thom, Kampong Chhnang, Phnom Penh, and Bavet town in Svay Rieng with plans to connect to Ho Chi Minh City via Moc Bai.

Plans also call to convert the existing Northern and Southern Railway Lines into high-speed rail, enabling trains to reach speeds of up to 160 km/h.
