Infraestruturas de Portugal has awarded Mota-Engil a €114M contract to quadruple rail capacity on the Linha do Minho between Contumil and Ermesinde, a strategic bottleneck serving both commuters and freight traffic toward Spain's Galicia region.
Why This Matters
• Journey reliability: Separate corridors for Linha do Minho and Linha do Douro will reduce congestion for Metro do Porto commuters and long-distance passengers.
• Freight capacity boost: The upgrade will significantly expand freight capacity on the line, supporting exporters using the port facilities and connecting to Spain.
• Timeline: Work begins this month and runs through early 2030—expect station closures and bus substitutions at Rio Tinto and Águas Santas.
• EU funding: The project receives support from Portugal 2030 cohesion funds and European investment backing.
Station Overhauls and Infrastructure Work
The 1,385-day contract centers on expanding the existing double-track railway to four tracks along the Contumil–Ermesinde corridor, a 10 km stretch that forms a key section of the Porto Metropolitan Area rail network. The Portugal Transport Infrastructure Agency (IP) identified this section as a significant capacity constraint on the Minho line, which stretches 134 km from Porto to the Valença border crossing.
Mota-Engil's scope includes rebuilding Rio Tinto station and the Águas Santas halt with wider platforms, improved accessibility ramps, and expanded car parks to serve growing ridership. Engineering work will also address Contumil and Campanhã stations. Critically, the project will eliminate multiple level crossings—road and pedestrian intersections that currently force trains to slow—and replace them with grade-separated underpasses and overpasses.
Catenery modifications, embankment reinforcement, drainage systems, and retaining walls round out the civil works. The result: a segregated corridor that lets suburban Metro do Porto services run independently of intercity and freight traffic.
Cross-Border Freight Significance
The quadrupled track will substantially increase daily freight capacity on the Linha do Minho, a critical artery connecting the Port of Leixões and Matosinhos industrial zones—which export textiles, machinery, and automotive parts—to Galicia and the broader Iberian peninsula.
The line connects to broader EU transportation corridors designed to funnel container traffic from Sines deep-water port to central Spain, supporting Portugal's logistics sector. Spain's rail operator Renfe has indicated interest in utilizing the expanded capacity for cross-border freight once the upgrade is complete.
Impact on Commuters and Regional Mobility
For residents of the Porto Metropolitan Area, the project promises faster, more reliable commutes. The current double track forces suburban, regional, and freight trains to queue, causing cascading delays. Separate tracks will allow tighter service frequencies and reduce journey times for passengers heading to Braga, Barcelos, and Viana do Castelo. The new platforms at Rio Tinto and Águas Santas will also accommodate longer suburban units, easing peak-hour crowding.
Budget travelers relying on public transport will benefit from improved service reliability without immediate fare increases, as IP's capacity boost enables additional services. However, expect weekend and night-time bus substitutions between 2026 and 2029 as construction crews close tracks in phases.
Contractor and Employment
Mota-Engil, a Matosinhos-based company with extensive experience in Portugal's motorway and metro networks, will manage the project. The contract will generate direct employment in civil engineering, electrical work, and rail installation, with additional work for subcontractors and local suppliers in the Porto region supporting concrete production and material logistics.
IP's project management team will oversee compliance with EU interoperability standards and Portugal's railway safety regulations, ensuring the upgraded corridor meets European safety and operational requirements.
Funding and Project Management
The €114M Mota-Engil contract is part of the broader infrastructure investment for the Contumil–Ermesinde quadruplication, supported by EU cohesion funds and European investment mechanisms for sustainable transport infrastructure.
IP has committed to progress reporting on construction milestones and maintaining communication with residents affected by construction activities. The company has established protocols for managing construction disruptions including noise and access restrictions.
