 Work is now under way to rehabilitate further sections beyond these main termini, such as between Heredia and Alajuela, and from Cartago to Paraiso, in order to extend the existing services.Trains (particularly freight trains, as well as a privately operated tour train) ran between San José and the port of Caldera until 2011, when a short section of the line was compromised following the construction of Route 27.This prompted a dispute between Incofer and the highway developer, Autopistas del Sol.
