The disruption began on the morning of March 14, when large rocks from a mountainside at a construction site fell onto the railway, breaking rails and derailing the locomotive of a freight train.
Although the line was briefly reopened later that day, further rockfalls from the slope forced authorities to shut it down again to ensure safety.
According to Vietnam Railways, hundreds of workers were deployed to clear the site, remove unstable rocks from the slope and repair damaged sections of the track.
After reopening, freight trains were allowed to run first at a limited speed of 5 km/h before gradually increasing. Passenger services resumed from midnight on March 17.
During the closure, four tourist trains operating between Hue and Danang were suspended, while train SE18 departing from Danang was also halted.
Passengers on several North-South services, including SE2, SE4, SE6, SE8 and SE10, were transferred by road between Lang Co and Danang stations.
Over the three-day disruption, the railway sector cancelled 12 passenger services and arranged alternative transport for 31 trains, affecting more than 5,600 passengers. More than 3,200 tickets were refunded.
Transport losses are estimated at around VND 10 billion, excluding infrastructure repair costs.
