The Porto Metro (Metro do Porto) opened on 7 December 2002 (exactly 9 years ago today) and runs along the city of Porto (in the north of Portugal) and the surrounding municipalities. It runs mostly above the ground, thus earning some unfair mockery from the users of the Lisbon Metro, who consider it more of a tram. However, in terms of extent, the Porto Metro outperforms Lisbon’s subway and tram services put together: 80 stations over 67 km of line.

The Porto Metro service is organized over 6 lines, labeled with letters from A to F and bearing a different colour each. Five of the lines (all but Line D) share a common segment within Porto’s city centre; Line D crosses this segment at the Trindade station, turning it into the network’s main hub. In detail, here are the lines with colours and terminal stations:

• Line A (blue): Estádio do Dragão – Senhor de Matosinhos
• Line B (red): Estádio do Dragão – Póvoa de Varzim
• Line C (green): Campanhã – ISMAI
• Line D (yellow): Hospital São João – Santo Ovídio
• Line E (violet): Estádio do Dragão – Aeroporto
• Line F (orange): Senhora da Hora – Fânzeres

Plans for future expansion include both extending currently existing lines and creating new ones.
