Starting in Hanoi, the Reunification Express runs the length of the country right down to Ho Chi Minh City in the south, of which the finest segment is the first half of the journey to Da Nang.
Conde Nast Traveller said threading deep into the capital city, the train offers voyeuristic views into the backs of houses as families unwind for the night, before emerging into glorious sunshine the following morning.
At the final stretch, the train curls around the clifftops overlooking the sea where a finger of golden sand runs along the edge of the water in Lang Co Bay, before finally pulling into Da Nang Station.
Other train journeys in Asia are also named in the list, including Tokyo to Osaka, Japan, by Tokaido Shinkansen; Ulaanbaatar of Mongolia to Beijing, by the Trans-Mongolian Express; Bangkok to Nam Tok by Thailand’s Death Railway; Xining to Lhasa, China, by Qinghai-Tibet Railway; and Mumbai to Madgaon, India, by the Mondovi Express./.
