Wildfire disrupts Madrid-Barcelona rail as Spain braces for heatwave

A wildfire in Catalonia cut one of Spain’s busiest rail arteries just as the country moved into its first major heatwave of the season, showing how quickly fire risk and transport disruption can collide. Adif said service on the Madrid-Barcelona high-speed line was interrupted on the Lleida-Pirineus to Camp de Tarragona stretch at 11:15 on June 18 after flames broke out near the track between Les Borges Blanques and L'Espluga de Francolí.

Renfe suspended trains on the affected segment at the request of firefighters, who were working to contain the blaze near the line. By 16:00, Adif said service was being restored after firefighters authorized normal operations and the catenary was re-energized, reopening the corridor that links Spain’s capital with Barcelona through northeastern Catalonia.

The disruption landed on a day when AEMET warned that temperatures were set to climb sharply from Saturday and could peak on Monday in many areas. Its forecast for June 18 called for highs of 36C to 38C in Spain’s northeastern third, 38C to 39C in the Tajo, Guadiana and Guadalquivir valleys, and locally 40C in the Guadalquivir valley. The agency also said dry storms with little precipitation would raise fire danger, even as the full intensity and duration of the heatwave remained uncertain.

The rail shutdown underscored a broader pattern that has been tightening across the Iberian Peninsula. Reuters noted that Spain and Portugal endured a 16-day heatwave last summer that was the most intense on record and helped fuel devastating forest fires. Scientists have linked the increasing frequency of such extremes to human-caused climate change, turning what once looked like separate crises into a single stress test for roads, rails, power systems and emergency crews.

Spain has already logged a string of exceptional heat markers. AEMET said 2025 was the country’s third-warmest year on record, and it recorded 25 single-day heat records over the year. The agency has also said spring 2026 was the second warmest in the historical series, adding to the pressure on transport operators and firefighters now trying to keep one of Europe’s key intercity links moving through a hotter, drier season.
