==Recent and Future Changes ''(most recent entries at top)''==
The governmental 'strategic infrastructure plan' in preparation in summer 2018 contains no investment for the Casa Branca - Beja or Régua - Pocinho lines. They may therefore be in danger of closure, especially the latter which is not in good condition.
In July 2018 the national environment agency APA approved plans for the modernisation of 87 km of the Linha do Oeste between Meleças and Caldas da Rainha, including electrification. Tenders for the work can now be issued. 2 km around Outeiro will be realigned and Meleças - Pedra Furada (10 km) and Malveira - Sapataria (6 km) double-tracked. Caldas da Rainha - Louriçal is not included and will continue using diesel railcars.
The long promised new freight line [South International Corridor] connecting the ports of Sines, [with connections from Setúbal and Lisboa] to Caia on the Spanish border near Badajoz is inching forward. On March 5 2018, there was a ceremony in Elvas to mark the start of work on the 79∙4 km of new alignment between Évora and Elvas on gauge-convertible sleepers. The route is to be electrified at 25 kV 50 Hz with three tenders for different sections to be followed by a contract for tracklaying and electrification of the 105 km between Évora and Caia.
Nine - Valença is to be electrified by the end of 2019. It is planned that Tunes – Lagos and Faro – Vila Real de Santo António sections will be electrified by the fourth quarter of 2020.
