Public transportation services in Porto have undergone various updates regarding infrastructure and vehicle maintenance. In July 2026, the historic electric tram line 22 resumed service following a five-year suspension caused by Metro Linha Rosa expansion construction. The line provides a circular route between Carmo and Batalha.

In August 2026, the Portuguese government addressed technical issues regarding Metro do Porto's Eurotram vehicles. Following service interruptions due to air conditioning failures during summer heatwaves, authorities confirmed the vehicles have approximately ten years of remaining useful life. The Ministry of Infrastructure and Housing is implementing measures to improve thermal comfort, including the refurbishment and installation of higher-performance HVAC systems.
