A Ouigo train from Madrid (Spain) to Barcelona stops near Cetina,while the train pantograph got caught in catenary,entangled and being dragged before it comes to standstill.Part of the contact wire were found wrapped around the rear of the train.This incident occured on May22,2022 around 2.35.P.M Spanish time  on train 06741.Traffic was interrupted for four hours.Although an investigation is being carried out into what happened,the first suspicions pointed to a 'hook' of the pantograph in the contact wire of the catenary.Poor maintenance of the train or overhead catenary could also be the cause,however it is also heard that the contact wire have come lose before the arrival of the train,causing it to hit the ceiling of the entire composition and roll that way over the rear headwall.Given the fact that this train use the rear pantograph and front end has been left intact,this theory would gain weight .Passengers claimed heard noise and they were evacuated safely by the rescue staff.
