The train service between Caminha and Espinho is primarily operated by Regional trains, specifically the Alfa Pendular and Intercidades options. The Alfa Pendular trains are known for their comfortable seating and enhanced amenities, reaching speeds of up to 220 km/h (137 mph). However, it's important to note that this high-speed service does not run the entire distance directly. Travelers may expect a journey time of approximately 3 hours, as these trains make several stops along the way, including key cities such as Viana do Castelo and Vila Nova de Gaia.
On the other hand, Intercidades trains also service this route but typically travel at a slightly lower speed, averaging around 160 km/h (99 mph). They offer similar seating classes and amenities, making them a good option for those looking to travel at a more moderate pace while still offering a reliable service. Overall, Alfa Pendular is recommended for those prioritizing speed, while Intercidades is suitable for broader access to local destinations.
