TNT Tren de la Mina, Parque de Atracciones, Madrid, Spain

At least 26 people, including six children under the age of ten, were injured when two coaster trains collided. One train appeared to be stuck and workers were trying to push it forward when the other train crashed into it. Riders were not able to brace for impact because they were wearing virtual reality headsets. Source
