Renfe AVE
The incumbent. Widest network, biggest choice of departures, priciest walk-up fares.
Route guide
Four companies now fight over this one line, and it shows in the fares: Ouigo and Avlo routinely sell seats for under €20 while Renfe's flexible AVE ticket can pass €130 on the same morning. Nothing else in Europe is this competitive.
The incumbent. Widest network, biggest choice of departures, priciest walk-up fares.
Renfe's budget brand on the same tracks. Single class, paid extras, seats sell out early.
French-run double-deckers. Often the cheapest ticket on the route; limited stations.
The newest entrant. Comfortable, competitively priced, fewer daily departures.
Compare every operator on this route in one search. Advance fares climb as seats sell.
Services run up to 3 per hour, with the first departure around 05:50 and the last around 21:30. Times shift with the seasonal timetable, so treat these as planning anchors and confirm the day before you travel.
Spanish high-speed fares behave like airline fares. Sales usually open two to four months ahead, and the cheapest Ouigo, Avlo and Iryo seats disappear first. Booking two to three weeks out typically lands close to the floor price; walking up on the day can cost four times as much. The cheap fares are also the strictest — changes cost money, refunds often are not an option.
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.

Madrid has two long-distance stations. Atocha serves the south, east and Barcelona; Chamartín serves the north and northwest. They are 25 minutes apart on Cercanías line C-1 — check your ticket twice.
Every high-speed service uses Sants, not Passeig de Gràcia. Metro L3/L5 run from beneath the concourse into the old city.
Coach: ALSA and FlixBus link Madrid and Barcelona for less money and roughly double the time — the budget backstop rather than a real rival. Driving: about 621 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 30 min – 3 h 10 min, with services running up to 3 per hour.
Advance fares start around €9.00; buy on the day and you can pay up to €135.
Departures leave from Madrid Puerta de Atocha and arrive at Barcelona Sants.

Roughly 05:50 and 21:30, varying by day of the week and season — confirm before you travel.
If price decides, compare Ouigo, Avlo and Iryo first — they undercut Renfe's AVE on most departures. If you want flexible tickets, seat choice or a specific arrival station, AVE still has the widest timetable. All of them use the same tracks and take the same time.
