Progress in Porto's Metro System
Porto's Pink Line Project Delayed but On Track for Q1 2026
The highly anticipated Pink Line project in Porto, Portugal, is currently facing a delay in its completion. Originally scheduled for July 2022, the final tunnel between Casa da Música and Galiza is now expected to open in August 2025, with full commercial operations commencing in the first quarter of 2026, around March-April or possibly as late as July 2026 [1][2][3].
The delay in the project's completion is attributed to the complex geological characteristics and geotechnical engineering of the terrain, as explained by Tiago Braga, president of Porto Metro [1][2]. Despite the setbacks, Braga maintains a positive outlook, stating that around six months are needed after the tunnel opening to fully complete the works and prepare for commercial service. The increased project costs, now totalling approximately €511 million (combined with the Yellow Line), reflect both the technical difficulties and rising construction material costs [3].
The Pink Line will connect key stations, including São Bento and Casa da Música, and intermediate stops such as Hospital de Santo António and Praça da Galiza. These connections aim to ease congestion on central metro hubs and improve east-west travel in Porto [2][3]. The Casa da Música station will serve as the terminus for both the Pink Line and the Ruby Line.
Cristina Pinto Dias, the Secretary of State for Mobility, has emphasized the importance of meeting decarbonisation goals, with 29% of transportation energy needing to be renewable by 2030. She also highlighted the need for a cultural change and a shift from individual to public transportation [4].
Tiago Braga, president of Porto Metro, considers the opening of a tunnel to be the most important milestone in any geotechnical project. He also mentioned that everything possible was done to ensure the project was completed under the best possible circumstances, with safety being a 'red line' [1]. Technical issues have made it difficult to understand the behavior of buildings and the context after a project, according to Braga, but he assured that the project had to proceed in a specific way due to the technical conditions.
In summary:
- The Pink Line project in Porto is currently delayed, with full commercial operations expected in Q1 2026.
- The delay is attributed to the complexity of the infrastructure work and associated construction challenges.
- The Pink Line will connect key stations, including São Bento, Casa da Música, Galiza, Hospital de Santo António, and Praça da Galiza.
- The project cost is approximately €304.7 million for the Pink Line, with the combined cost of the Pink and Yellow Lines totalling approximately €511 million.
- The Casa da Música station will serve as the terminus for both the Pink Line (São Bento - Casa da Música) and the Ruby Line (Santo Ovídio - Casa da Música).
- The project, approximately 3.5 kilometres long, is entirely underground.
