Hun Sen and Prayut travelled over the newly-completed 1.3km section between Ban Khlong Luek in Thailand and Poipet in Cambodia and witnessed the signing of a bilateral agreement on cross-border rail transport.

To mark the occasion, Thailand donated a metre-gauge DMU to Cambodia. The four-car train seats 360 passengers.

Rail links between the two countries were severed in 1974 due to the civil war in Cambodia, which inflicted severe damage on the country's rail infrastructure. The two governments reached an agreement in October 2014 to reinstate the Ban Khlong Luek - Poipet crossing and the Thai government provided a grant to reconstruct a 45m-long bridge on the cross-border section.

The Asian Deveopment Bank is financing the rehabilitation or rebuilding of 641km of railway in Cambodia. Reconstruction of the final section of the 386km Phnom Penh - Poipet line was completed in July 2018.

On the Thai side of the frontier, State Railway of Thailand (SRT) has rehabilitated the 6km line between Aranyaprathet station and the border at Ban Khlong Luek.
