Rehabilitation of Railway in Cambodia Project The Rehabilitation of Railway in Cambodia Project supports the Asian Development Bank to upgrade the national railway of Cambodia: southern railway (254km from Sihanoukville to Phnom Penh) and northern railway (388 km from Phnom Penh to Poipet on Thai border). The majority of this funding will purchase rail sleepers, fund rehabilitation activities, and undertake related public works and upgrades at railway stations. The improved rail line will increase container traffic and trade between Cambodia and its neighbours, and reduce costs associated with road maintenance. The total value of this initiative is $27.1 million over a 7 year period, starting 2008-09.
