"el gran capitán" 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 once rail disaster.
