Traveling from Viana do Castelo to Pombal, the journey is primarily serviced by the Intercity and Regional trains operated by Comboios de Portugal (CP). The Intercity train is the faster option, reaching speeds of up to 160 km/h (99 mph) and completing the journey in approximately 3 hours. This train provides a more direct route with fewer stops, making it a preferred choice for those prioritizing time.
On the other hand, the Regional train serves the same journey but at a slower pace, averaging around 100 km/h (62 mph) and taking about 4 hours to reach Pombal. While it stops at additional stations such as Braga and Leiria, this train offers a closer look at the beautiful Portuguese landscape and allows passengers to disembark at smaller towns along the way.
Both services offer comfortable seating and scenic views, but the Intercity train is the better choice for travelers looking to minimize travel time, while the Regional train caters to those who wish to explore more on their journey.
