The Government of Cambodia plans to upgrade the existing Phnom Penh-Poipet railway to a high-speed rail (HSR) line. According to results of a feasibility study conducted by the China Road and Bridge Corporation (CRBC), the rail project will cost around USD4 billion and will take around four years to complete.

Construction is expected to commence soon, although an exact timeline has not been provided.

The 384-km-long HSR line, with 33 stations, will be used for both passenger and freight transport between Cambodia and Thailand. The HSR will connect the Kandal, Kampong Chhnang, Pursat, Battambang and Banteay Meanchey provinces. The line will feature electric rail cars with a maximum speed of 160km/h and will be the first express railway in Cambodia.
