Running the full length of Vietnam from Hanoi to Ho Chi Minh City — a distance of roughly 1,730 km — the Reunification Express is one of Asia's great rail journeys. It is slow by high-speed standards, taking around 30–36 hours for the full run, but the scenery ranges from rice paddies to dramatic coastal cliffs, the train passes through a string of compelling cities, and the journey itself becomes part of the Vietnamese experience rather than something to endure.
Vietnam Railways: the basics
Vietnam Railways (Đường sắt Việt Nam) operates all intercity trains on the single-track main line that connects Hanoi (Hà Nội) in the north with Ho Chi Minh City (Sài Gòn) in the south. The railway was rebuilt and reunified in 1976 after the war — hence the name — and it remains a vital link across the country's considerable length.
Key services are the SE trains (Thống Nhất Express) and TN trains, with the SE series being faster and better quality. The SE1 and SE2 are the flagship expresses covering the full Hanoi–HCMC route; lower SE numbers (SE1, SE3, SE5, SE7) typically travel southbound, while evens (SE2, SE4, SE6) go north. There are also faster local services on popular segments like Hanoi–Da Nang and Da Nang–Ho Chi Minh City, which can be useful if you are breaking the journey into legs.
The four ticket classes
Vietnam's trains offer four main classes of travel, and the difference in comfort and price between them is significant:
- Soft sleeper, air-conditioned (4-berth): The recommended choice for long-distance journeys. Clean four-berth compartments with padded berths, air conditioning and a door. Upper berths are slightly cheaper; lower berths are easier to use during the day. This is the equivalent of Chinese soft sleeper.
- Hard sleeper, air-conditioned (6-berth): Open-plan berths in bays of six, with air conditioning. Noticeably cheaper than soft sleeper, and perfectly comfortable for most travellers. The top berth gives the least headroom and privacy.
- Soft seat, air-conditioned: Reclining seats, air-conditioned. Good for shorter legs (Hanoi to Da Nang, say) but less comfortable for overnight journeys.
- Hard seat: The cheapest option, suitable for short daytime trips. For journeys over four or five hours, the lack of padding becomes an issue. Locals on short runs use these often.
For journeys of more than a few hours — and certainly for overnight legs — a soft or hard sleeper is well worth the modest premium over seats.
The Hai Van Pass: Vietnam's most scenic rail moment
Of all the segments along the Reunification Express, the crossing of the Hải Vân Pass (Đèo Hải Vân) between Da Nang and Hue is the most celebrated. The railway hugs the mountainside as it climbs above the South China Sea, offering views of the coastline far below and forested peaks above. The pass separates the cooler north from the more tropical south, and the weather can be dramatically different on each side.
The crossing takes about 45 minutes at train speed, and the best views are on the seaward side (the right-hand side travelling south from Hanoi). If you are on a direct through-train, you experience this without planning; if you are breaking the journey at Da Nang or Hue, time your departure to cross the pass in daylight.
Key journey segments
Few travellers take the full 30-plus-hour Hanoi to Ho Chi Minh City run in one sitting, though some do for the experience. The journey breaks naturally into sections:
- Hanoi to Hue — about 12–14 hours, a popular overnight option on the SE trains. Waking up in Hue after departing Hanoi the previous evening is one of the more pleasant aspects of the overnight service.
- Hue to Da Nang — about 2.5 hours, including the Hai Van Pass crossing. Worth doing in daylight purely for the scenery.
- Da Nang to Nha Trang — about 10–11 hours, another good overnight segment.
- Nha Trang to Ho Chi Minh City — about 7–8 hours, usually a daytime run.
Hoi An is not on the rail line — the nearest station is Da Nang, roughly 30 km away, easily reached by taxi or bus.
Booking tickets
The official booking platform is the Vietnam Railways website (dsvn.vn), which now accepts foreign credit cards with improved reliability. Third-party aggregators (Baolau, 12Go Asia) also handle bookings with an English interface and are a useful alternative if the official site gives trouble. Booking at the station is possible but the queues and language barrier can be challenging in busy periods.
Book at least a few days ahead for popular segments and sleeper berths — the lower berths in soft sleeper compartments sell first. Around the Tết New Year holiday, trains are packed and should be booked weeks ahead if you are travelling during that window.
Practical tips
Food service on Vietnamese trains varies — a basic trolley service runs on most expresses, selling instant noodles, drinks and snacks. For anything more substantial, bring food from the departure station. Hawkers also sell food at station stops. Bedding is provided on sleeper classes on the SE trains; a light travel blanket is still useful as air conditioning can be set very cold.
Bathrooms are at the end of each carriage and are cleaned at interval — they are functional but basic, particularly after the first few hours. A small supply of hand sanitiser and toilet paper is never wasted.
Is the train or bus faster between Vietnamese cities?
On the Hanoi–Ho Chi Minh City axis, flying is almost always the fastest option, and for budget travellers there are frequent cheap domestic flights with VietJet Air, Bamboo Airways and Vietnam Airlines. The overnight sleeper bus is another common budget option for medium-distance legs. The train occupies a comfortable middle ground: slower than flying, more comfortable than the average overnight bus, and far better for scenery than either.
Frequently asked questions
How long does the full Hanoi to Ho Chi Minh City train take?
The fastest SE trains complete the journey in around 30–33 hours. Most practical itineraries break the route into two or three legs with overnight stops at Da Nang, Hue or Nha Trang.
Which class should I book for an overnight Vietnam train?
Soft sleeper air-conditioned (4-berth) is the most comfortable and recommended for most travellers. Hard sleeper (6-berth, air-conditioned) is a perfectly acceptable and cheaper alternative.
Where can I book Vietnam train tickets online?
The official Vietnam Railways site (dsvn.vn) is the primary source. Third-party English-language platforms like Baolau and 12Go Asia also offer booking with foreign cards and a more accessible interface.
Is Hoi An accessible by train?
Hoi An has no railway station. The nearest stop is Da Nang, about 30 km away, from which taxis, minivans and local buses serve Hoi An in around 45 minutes.
