A commuter train struck a collapsed retaining wall near Barcelona, killing the driver and injuring 37 people, four of them critically.

The accident occurred in Gelida after the wall fell onto the tracks, likely due to heavy rainfall in the region.

Emergency services deployed dozens of firefighters and ambulances, and authorities confirmed no passengers remained trapped in the carriages.

The incident came just two days after a deadly high-speed train collision in southern Spain that killed at least 42 people, The Guardian has reported.

The crash has renewed attention on Spain’s underfunded rail infrastructure as the country observes days of mourning.
