Caminha sits on Portugal's Linha do Minho, the coastal and border railway linking Porto with Viana do Castelo and Valenca. The town has one main passenger train station, Caminha, and rail services are operated by Comboios de Portugal, usually branded as CP. Its rail role is regional rather than high-speed, connecting the Minho coast with Porto's wider national network.
Trains from Caminha include CP Regional and InterRegional services using the Minho Line. Caminha station handles local and regional trains rather than Alfa Pendular or Intercidades high-speed style services. Passengers heading beyond northern Portugal usually connect at Porto Campanha, Nine, or Valenca, depending on whether the trip continues south, inland, or toward the Spanish border.
Rail routes from Caminha run south toward Viana do Castelo, Barcelos, Nine, and Porto, and north toward Valenca at the Portugal-Spain border.
