Linha de Leixões

Linha de Leixões, (also known as Linha de Cintura do Porto, or Linha da Circunvalação de Leixões) is a railway line in Portugal which connects the railway stations of Contumil in Porto and Leixões, in Matosinhos. The line opened in 1938, connecting the Port of Leixões to the Minho Line and to the rest of the Portuguese railway network, serving as an important link for cargo. It is an electrified single track in Iberian gauge stretching over 18.9 kilometres (11.7 mi), equipped with EBICAB 700 control systems and RSC communications.

Passenger services had previously run until 1987 and between 2009 and 2011. Passenger services restarted in 2025, between Leça do Balio and Contumil, with Campanhã or Ovar as their destination. During weekdays, 60 passenger trains are operated per day, 30 in each direction, with up to two trains per hour, whereas only 34 trains run during weekends. The travel time between Campanhã and Leça do Balio ranges from 19 to 27 minutes, depending on the schedule.

While passenger services did not resume on the segment between Leça do Balio and Leixões, a bus service was arranged, starting in March 2025. This is expected to help measure the demand for such a service. The terminus in Leixões would allow for a connection with Porto Metro at Senhor de Matosinhos.
