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, 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. Currently many of these lines are being renovated with the intention of improving services.
