The train service between Entroncamento and Santo Tirso is primarily served by the Regional train, specifically the Comboios de Portugal (CP) service. This connection features trains that typically operate at speeds ranging from 80 km/h to 120 km/h (50 to 75 mph) depending on the segment of the route. The journey usually lasts approximately 2 hours, with a few stops at key stations along the way such as Tomar and Vila Nova de Gaia. This route primarily features conventional trains rather than high-speed options, hence it centers more on regional travel. Passengers can expect basic amenities on board, including comfortable seating and the ability to transport bicycles. While travel times may be longer compared to dedicated high-speed services, the Regional trains facilitate access to smaller towns and offer a glimpse into the scenic Portuguese countryside.
