Traveling from Estarreja to Entroncamento, the primary train service is provided by Comboios de Portugal, specifically on the Intercidades and Regional trains. The Intercidades service typically reaches speeds of up to 160 km/h (99 mph), covering the distance in approximately 2 hours and 30 minutes. It operates with fewer stops, making it the faster option for this route. On the other hand, the Regional trains, while offering a more frequent schedule, take closer to 3 hours due to additional stops at smaller stations along the way.
Passengers can expect onboard amenities like comfortable seating and access to refreshments, though the Intercidades service is designed for those who prioritize speed and efficiency. Both services offer standard class seating, but the Intercidades may feature more spacious arrangements.
