The railway line connecting the Phnom Penh train station to the airport was launched on Tuesday morning in a bid to ease traffic flow.
Sun Chanthol, Minister of Public Works and Transportation, said on Tuesday that the train service would make it convenient for passengers to bypass much traffic.
“The airport railway service will help passengers to skip the busy traffic on the road from the city to the airport,” Mr Chanthol said.
The train service is free for passengers living within the vicinity of the Phnom Penh International Airport from this month till July.
The train will use three train engines imported from Mexico for passenger transport, with each train able to carry 100 passengers.
Full service will be ready in June, Mr Chanthol said.
