The Douro Line (Porto–Pocinho) will be closed between Marco de Canaveses and Régua from 3 November 2025 until early April 2026 for modernisation works being launched by Infraestruturas de Portugal (IP), seven years later than initially planned.
Structural interventions will be carried out in the six tunnels along the section, with major works in the Juncal tunnel, which is 1,624 metres long. The company cites the high technical complexity of the project as the reason for the closure.
The suspension has drawn criticism due to IP’s repeated delays in previous railway projects. A striking example is the Beira Alta Line, which was expected to be closed for nine months from April 2023 but only resumed service last September — three and a half years later.
