Travel to Buenos Aires by Train
Travelling to Buenos Aires by train — and from the city across Argentina — is a comfortable, affordable and characterful way to get around. Long-distance intercity and interprovincial services are operated by Trenes Argentinos, the state-owned rail company. The city also has an extensive suburban rail network connecting Buenos Aires with Greater Buenos Aires and popular destinations such as Tigre, La Plata and Mar del Plata. To use the urban train network you will need a SUBE card — the integrated payment card for all public transport in Buenos Aires.
Retiro Station
Retiro Station is Buenos Aires’ main railway terminal and one of the most important in Latin America. It is located in the heart of the city centre, facing Plaza San Martín and just steps from the Río de la Plata. The building itself — built in 1915 in an English architectural style — is a landmark well worth admiring. Retiro functions as the great transport hub for northern and western Argentina.
The following lines operate from Retiro:
Mitre Line
Connects the city centre with the northern suburbs of Greater Buenos Aires, reaching destinations including Tigre and Bartolomé Mitre. The Tigre branch is especially popular with visitors, as it connects directly with the Tigre Delta.

Belgrano Norte Line
Connects the city centre with the northern neighbourhoods and Greater Buenos Aires up to Villa Rosa.
