Hanoi Railway Transport JSC, the northern operator, has cancelled trains from Vinh, capital of central Nghe An Province, to Hanoi starting Friday.
It also announced the suspension of trains connecting Hanoi with northern port city Hai Phong, home to Do Son Beach and UNESCO heritage site Cat Ba National Park, and northern Lao Cai Province, famed for resort town Sa Pa.
A company representative said train travel demand often decreases in May since many people had already returned to their hometowns during the Reunification Day (April 30) holiday while Hanoi and northern provinces are struggling with a new wave of Covid-19, leaving many areas under lockdown.
Travel destinations in Hanoi, Hai Phong and northern provinces like Quang Ninh, Ha Nam, Thai Binh and Nam Dinh have stopped receiving tourists amid the surge in community transmissions.
Saigon Railway Transport JSC, the southern operator, will suspend several trains from Ho Chi Minh City to Nha Trang, a popular beach town in central Khanh Hoa Province, from Sunday.
Vietnam has recorded 121 Covid-19 community transmissions since April 27. Previously, it had been clean for over a month.
