The Celta train is a train connection from the Portuguese railway operator Comboios de Portugal and the Spanish railway operator Renfe Operadora between Campanhã railway station in Porto (Portugal) and Vigo-Guixar railway station in Vigo (Spain). It became the only international rail service between Portugal and Spain after the discontinuation of Trenhotel in 2020.
The service runs twice every day in each direction, taking 2 hours and 20 minutes to connect both cities. [1]
