General Urquiza Railway

Urquiza Line rolling stock.

In the metropolitan sector of the City of Buenos Aires there is an electrified commuter branch that operates from the Federico Lacroze terminus in the Buenos Aires neighbourhood of Chacarita, to the General Lemos station in suburban San Miguel. The branch is the only electrified part of the railway and the only part which is operated for passengers by a private company, Metrovías.[8] It connects with Line B of the Buenos Aires Underground at Federico Lacroze station.[9]

The line was originally designed to be part of Underground Line B with a ramp taking it underground at its current terminus, though this was never implemented. It is still possible that the existing ramp would allow connection to line B, enabling trains to run through to the centre of Buenos Aires, though this has still yet to be done to this date.

Posadas Station exterior.

El Gran Capitán (english: The Great Captain) was a service that ran from Buenos Aires to Posadas under Ferrocarriles Argentinos (FA) and later under Trenes Especiales Argentinos (TEA). With the dissolution of Ferrocarriles Argentinos, the interurban and long-distance services ceased to run in 1993, but in 2003, TEA revived the passenger rail service from Buenos Aires to Posadas, capital of the Province of Misiones. This service ceased to operate in November 2011, though it was briefly re-activated in 2012 under the company Trenes de Buenos Aires until the national government revoked all their concessions later that year following the Buenos Aires rail disaster.[10]

Since then, there have been numerous calls for the return of the service given the large-scale reactivation of many of the country's railways since 2014.[11][12]

Some interurban services in the Province of Entre Ríos also exist, such as the service from Paraná, Entre Ríos to Concepción del Uruguay and the service from Basavilbaso to Concordia,[13] both of which were originally part of the Central Entre Ríos Railway. These use Materfer rolling stock and are operated by the state-owned company Trenes Argentinos.[14] Currently many of these lines are being renovated with the intention of improving services.

The city of Paraná also uses part of the Urquiza railway for its own commuter rail network. Trains run six times a day on weekdays from Paraná to Colonia Avellaneda with 8 stations in between, while another service runs from Paraná to Villa Fontana twice a day on weekdays with four stops.[15] Both services have heavily subsidised prices for local residents.[16][17]

This Posadas-Encarnación service links the cities of Posadas in the Argentine province of Misiones to the city of Encarnación in Paraguay. It was opened in 2014 and is operated by Casimiro Zbikoski S.A. under the authority of the state-owned Trenes Argentinos using Dutch Wadloper rolling stock.[18] It currently carries 8,000 passengers daily and expansions are being considered as the service is already reaching its maximum capacity.[19]

The Tren de los Pueblos Libres (Train of the Free Peoples) was a short lived rural train service between Pilar in Argentina and Paso de los Toros in Uruguay. The service was closed in May 2012 after the Government of Argentina revoked all concessions to Trenes de Buenos Aires (the operator of the service)[20] after the Once rail disaster, which occurred on a service operated by that company.[21]
