There are two 1,000 mm gauge rail lines in Cambodia's 612 km (380 mi) network: one from Phnom Penh, the nation's capital, to Sihanoukville and another from Phnom Penh to Poipet, which is on the Thai border. The railways were constructed when the country was a part of French Indochina. However, in 2009, all services had been suspended because of neglect and damage from the civil war during the latter half of the 20th century. By 2016, freight and limited passenger service between Phnom Penh and Sihanoukville were restored thanks to rehabilitation efforts by the Cambodian government with assistance from the Asian Development Bank, the Australian Agency for International Development (AusAID), and the Australian company Toll Holdings. In 2019, passenger service between Phnom Penh and Poipet was fully restored.
