One of the deadliest rail crashes in Europe’s history has been caught on film.

On Wednesday night, a train derailed outside of Santiago de Compostela on the night of Saint James, major religious festival. The accident killed at least 78 people and injured 131 more.

One official said that the derailment may have been a cause of speeding. Sources close to the investigation said that the train was traveling twice the average speed limit.

Looking at the horrifying video, it seems as though speed was the reason, as the train is seen hurdling at bullet-speed around the curve and careening off the wall. Spanish newspaper El Mundo reported that the speed limit for turning on the curve is 50 miles per hour, but the train appeared to be approaching the Santiago station at 118 miles per hour.

Reuters reported, “Firefighters clambered desperately over the twisted metal trying to get survivors out of the windows, while ambulances and fire engines surrounded the scene. Cranes were still pulling out mangled debris on Thursday morning, 12 hours after the crash.”

Those who were a part of the relief effort were horrified at the aftermath.

We heard a massive noise and we went down the tracks,” Ricardo Martinez, a 47-year old baker from Santiago de Compostela, told Reuters. “I helped getting a few injured and bodies out of the train. I went into one of the cars but I’d rather not tell you what I saw there.”

All festivities in the city have been canceled due to the crash .
