A hundred ordnance clearers were deployed along the $5-billion Savannakhet-Laobao railroad, which will link northeast Thailand to central Vietnam, the Vientiane Times reported.
The line passes through Laos' Savannakhet province that was heavily bombed by the United States during the Vietnam War, leaving behind thousands of unexploded ordnances that continue to claim victims today.
"UXO (unexploded ordnance) clearance teams are working daily and have found a total of nine unexploded bombs at the proposed Nasy station alone," the report said, citing an update provided by contractor Giant Consolidated Limited.
The Malaysian firm signed an agreement with the Lao government in November 2012 to build the train track.
Digimap Sdn Bhd of Malaysia is completing the final survey of the rail line, the Vientiane Times reported, including clearing ordnances along the route.
