Although Renfe has given us some somewhat tortuous months in terms of its service, AVE delaysthe truth is that the train continues to be a very important means of transport in Spain, and there are many who prefer it to the plane. Factors like railway liberalization and the fierce price war Among the different railway operators they have also been especially favorable to this preference.
According to Renfe data to which El País has had access82% of travelers choose the train over the plane. And this from an environmental point of view is good, since as the media reminds us, this represents an annual savings in emissions that reaches 512,926 tons of CO₂, equivalent to removing about 250,000 combustion cars from circulation for an entire year.
Growth. The seven main routes, which connect Madrid with Barcelona, Seville, Malaga, Valencia, Alicante, Galicia and Asturias, have experienced growth of up to 66% in the number of travelers in the last three years, according to the data provided by the railway operator.
Numbers. Between September 2022 and August 2025, the Madrid-Barcelona corridor has gone from 7.5 to 8.9 million travelers. Madrid-Valencia rose from 4.4 to 5.3 million, while Madrid-Málaga jumped from 2.1 to 3.5 million, being the corridor with the most relative growth. According to account In the middle, these figures also include the users of Ouigo and Iryo, the private operators that have entered into competition after the liberalization of the sector.
The three hour rule. “As soon as the train offers a competitive travel time of less than three hours, demand shifts massively to the railway instead of the plane,” explains Adrián Fernández, director of Sustainability and Energy Efficiency at Renfe, to El País. Fernández presents the case of Madrid-Barcelona, since when the journey lasted seven hours, only 15% of the passengers chose the train; Now, with a two and a half hour trip, that proportion reaches 83%.
Where do new travelers come from?. Just like collect In the middle, the International Union of Railways estimates that 50% of current high-speed users come from the plane, 20% abandon the car, and the remaining 30% correspond to induced trips, referring in the latter to trips that were not made before having the AVE.
Savings Breakdown. The middle collect Renfe calculations based on European Commission methodologywhich state that the Madrid-Barcelona route avoids the emission of 185,856 tons of CO₂ per year. According to these data, Madrid-Seville saves 76,874 tons, and Madrid-Málaga reduces emissions by 72,121 tons. Adding the connections with Galicia, Valencia, Alicante and Asturias, the total amounts to 512,944 annual tons of CO₂.
The equivalent in cars. To measure this figure, the Institute for Energy Diversification and Saving (IDAE) esteem that each car traveler emits 121 grams of CO₂ per kilometer, as points out The Country. Considering that a vehicle travels about 11,200 kilometers per year in Spain with an average occupancy of 1.5 people, the savings are equivalent to removing 252,325 cars circulating throughout the year.
Challenges. Although the train is more sustainable, Cristina Arjona, Greenpeace mobility spokesperson, counted to El País that “to encourage its use even more it must also be the most competitive in price, since sometimes it is still more expensive than the plane.”
“As high speed reaches new corridors, as soon as times are competitive, people decide to use the train en masse, with quotas of 80% and 90%,” account Fernandez in the middle. Now the challenge for operators is to extend this network to more territories and ensure that the offer of frequencies and prices remains attractive.
