In 2026, the commuter train service between Lisbon and Sintra, operated by Comboios de Portugal (CP), remains highly frequent and reliable. Trains typically run every 20 minutes throughout most of the day, seven days a week. During the peak morning and evening rush hours, the frequency can increase to every 10–15 minutes to accommodate the high volume of commuters and tourists. The journey generally takes about 40 to 50 minutes depending on whether you depart from the Rossio station (the most scenic, central option) or the Oriente station (better for those arriving from the airport or by long-distance rail). The first trains usually depart around 6:00 AM, and the service continues until approximately 1:00 AM. Because this is a suburban "Urban" service, tickets cannot be reserved in advance and there is no "limit" to capacity, so travelers simply "tap and go" using a Navegante card or purchase a paper ticket at the station for roughly €2.40 per journey.
