Rescue teams on are continuing to pick through the mangled wreckage of a passenger train that crashed head on with a freight train, killing 19 people in Spain's worst rail accident for 25 years.
Cranes in fields on either side of the crash site, about five km (three miles) from the small town of Chinchilla in southeast Spain, removed one of the wagons in the pile-up after Tuesday evening's crash.
Body parts were painstakingly recovered from the two carriages of the train where the victims had been sitting.
The chairman of Spain's state railway company RENFE told a news conference in the city of Albacete, near Chinchilla, the death toll could rise. Eight people were still in hospital.
"We don't rule out the possibility of finding more dead," said chairman Miguel Corsini.
He said the accident was caused by human error as the system which stops trains skipping red signals was working when tested the morning after the crash.
A local government spokeswoman said, however, she did not expect the number of dead to rise further.
"From when we arrived we knew no one was alive, that was absolutely certain," Antonio Peinado, head of the provincial fire service, earlier told reporters at the scene.
Police said identifying the charred remains would be difficult.
