The initial 11km section will run from Porto to São Vicente Barreiros Terminal, while the second phase comprises a 4km branch from Conselheiro Nébias to Valongo. The line is expected to carry around 70,000 passengers per day, reducing the city's bus fleet by 23%.

Thales' contract includes signalling and control systems, fixed and mobile communications systems, data transmission, multimedia solutions and the electronic traffic monitoring system.

The project has a budget of Reais 855m ($US 394m) and is due to be completed next year.
