Travelers on the Ovar to Trofa route can choose between the Intercidades and Regional trains offered by Comboios de Portugal (CP). The Intercidades service operates with a higher efficiency, reaching speeds of around 160 km/h (99 mph), allowing passengers to complete the journey in approximately 1 hour. This service features comfortable seating and amenities such as onboard snack and drink options. On the other hand, the Regional train travels at a slightly slower pace of around 80 km/h (50 mph) and takes around 1 hour and 30 minutes to cover the same distance. While it provides access to local stops, the increased travel time may not suit those looking for a quicker option. For optimal speed and a more direct travel experience, the Intercidades train is recommended, whereas the Regional train could be a suitable choice for passengers looking to explore smaller towns along the route.
