Compare every operator on this route in one search. Advance fares climb as seats sell.
Services run roughly hourly, with the first departure around 06:00 and the last around 21:00. Times shift with the seasonal timetable, so treat these as planning anchors and confirm the day before you travel.
Fares on this route are largely fixed, so there is little advantage in booking months ahead. Buy the day before or on the day in the operator's app, or at a station machine. Reserved seats still apply on long-distance services, so a sold-out train is sold out.
Tickets are digital: show the QR code in the operator app or a printout. High-speed and long-distance tickets are tied to a specific train and seat; regional tickets are more flexible but do not guarantee you a place.

All intercity trains use Campanhã, not the tiled São Bento. A free three-minute shuttle train links the two.
Long-distance trains call at Oriente first, then terminate at Santa Apolónia by the river. Oriente is better for the airport, Santa Apolónia for Alfama.
Coach: ALSA and FlixBus link Porto and Lisbon for less money and roughly double the time — the budget backstop rather than a real rival. Driving: about 310 km of autopista, plus fuel, tolls and the problem of parking in a historic centre. Flying makes no sense on this corridor: by the time you have reached the airport twice and cleared security, the train has already delivered you to the middle of the city.
Typically 2 h 50 min – 3 h 20 min, with services running roughly hourly.
