High-speed Madrid-Barcelona, a complex reform in the midst of a heated debate
Adif has considered stopping traffic on the line to speed up and ensure the reliability of the work to be carried out starting in 2027, which was approved by Óscar Puente and earned him a wave of criticism. Partial closures and extensions of the working time slots are also being analysed.
Just a year ago, the high-speed train rumbled along, embroiled in incidents, but it was experiencing a moment of historical demand driven by roughly 45 million users. On Monday, November 17th, 2025, a forum in Madrid brought together businesspeople and politicians to hear Transport Minister Óscar Puente announce an extensive overhaul of the Madrid-Barcelona line, the most used railway in the country.
He set the start of works for early 2027 and the goal of improving the comfort of travel, cutting the journey time to under two hours and expanding capacity. This project is causing a major stir as Adif, the company constructing and managing the rail network, debates the feasibility of halting traffic to undertake the renovations.
Alternative scenarios being considered, with less economic impact on mobility, include extending night-time maintenance windows, brief closures with alternative transport plans, and single-track circulation while work proceeds on the parallel line.
