Trains in Argentina: tickets, passes and routes

Argentina's rail network was cut back hard in the twentieth century, and what survives is mostly commuter services around Buenos Aires plus a handful of long-distance and scenic lines. For a first trip, treat rail as an experience, not as transport: the parent country guidance is to fly between regions (Buenos Aires–El Calafate 3–3.5 h, –Iguazú 2 h, –Mendoza 2 h, –Ushuaia 3.5 h) and to use buses for legs under about 10–12 hours.

The two trains most visitors actually book are tourist rides. Tren a las Nubes leaves from Salta and climbs into the Andes on a full-day excursion; the End of the World Train runs from near Ushuaia into Tierra del Fuego National Park. Both sell out in high season, so reserve before you arrive rather than at the platform. Long-distance services elsewhere are slow and infrequent, which is why they rarely beat a flight or a cama bus on time.

In Buenos Aires, the Subte plus the suburban rail lines and colectivos cover the city and its outskirts cheaply. Fares rose sharply in 2024–26; pay with a SUBE card, or a contactless bank card on many lines. Pickpockets work the rush hour, so keep phones inside.

Buy long-distance bus tickets online (Plataforma 10 or the company site) and only fall back on the Retiro terminal in low season. Keep valuables with you on overnight buses, not in the overhead rack.

For the tourist trains, book days to weeks ahead in peak season and confirm the departure point the day before; mountain weather can shift schedules. Carry your passport for park entries and some rail bookings.

If you are weighing rail against flying, run the numbers on a domestic flight first — the parent country guidance puts most regional hops at 2–3.5 hours for US$60–250 one way.
