The train services from Guarda to Caria are primarily operated by the regional train known as the Intercity. These trains do not reach high-speed levels typically associated with routes in larger metropolitan areas, making the journey significantly scenic rather than rapid. The Intercity trains operating on this route usually run at speeds ranging from 80 km/h (50 mp/h) to 120 km/h (75 mp/h), with travel times taking approximately 2 hours depending on the specific service and stops along the way. The route travels through picturesque landscapes and small towns, benefiting from the unique charm of the Portuguese countryside. It’s important to note that while the Intercity service is more comfortable than local trains, it doesn't offer the speed or amenities of high-speed rail systems found in other countries. Passengers can expect basic seating and occasional onboard refreshments, making this journey pleasant yet relaxed for those enjoying the sights.
