One unit of the series is involved in an accident in Valladolid-Campo Grande railway station.
In the early morning of March 3rd, 1988, the driver of the "Costa Vasca" express train from Madrid to Bilbao realised that something was wrong as he unsuccessfully tries to slow down his convoy while traveling at 75 kilometres per hour and fast approaching Valladolid-Campo Grande railway station. Despite all his efforts, the train collides with the "Cantabria" train stationed at platform 1.1 at around 45 km/h.
The freight car used for transporting cars at the end of the "Cantabria" convoy is propelled through the sleeping coach attached to it and penetrates like a pair of blades throughout the entire length of the car. The human toll: 8 dead and 30 injured.
