According to Malaysian online news, within the next few months, Cambodia will begin laying rail tracks donated by Malaysia.

Transport Minister Datuk Seri Chan Kong Choy said Friday the first load of tracks had arrived in Aranyaprathet, the Thai border town with Cambodia, and the transfer of five more batches would be completed by the middle of next month.
“The tracks arrived yesterday morning. Cambodia will commence work on the Poipet-Sisophon link by early next year and it will be completed in 2009,” Chan said after chairing the eighth special working group meeting on the SKRL here.

The entire route is part of the eastern link of the SKRL that will link the more developed Singapore, Malaysia and Thailand to the Indochina corridor and become an economic artery for Cambodia, land-locked Laos and Vietnam.
China also updated the meeting on the construction of two single electrified tracks totalling 300km to link up with Vietnam on the eastern SKRL route and close to another 1,000km over two stretches on the central route to connect with Myanmar.
