finally, on november 8, 1961, the government of argentina (led by arturo frondizi) decided to close the branch from bartlomé mitre to delta. only some freight trains would sporadically run through those tracks until they disappeared definitely. since the branch felt into disuse, the railway buildings and lands behind the tracks were illegally usurped by homeless families, while on the other hand, groups of neighbors claimed for the re-establishing of the services.
