A major disruption occurred in Madrid's Chamartín station on Monday due to a breakdown of the Avlo train service, which left passengers stranded for over two hours in a tunnel without air conditioning.

The train, traveling from Valencia to Madrid, experienced a malfunction near the Botanical Garden, causing a domino effect that delayed multiple other services.

Frustrated travelers reported extreme heat, leading some to break windows for ventilation.

Emergency services attended to nine individuals suffering from heat-related issues, with one elderly woman requiring hospitalization.

The incident sparked outrage on social media, with calls for improvements to the railway system and criticism directed at Transport Minister Óscar Puente.

The chaos at Chamartín resulted in overcrowding and a lack of basic amenities, as travelers waited for updates amid rising temperatures.
