Experts investigating the cause of a train crash in Spain that killed 40 people have found a broken joint on the rails.
The tail end of a train heading from Malaga to Madrid derailed at 7.45pm on Sunday, smashing into an oncoming train travelling from the capital to Huelva.
Investigators at the scene identified some wear on the joint between sections of the rail, known as a fishplate, which they said showed the fault had been there for some time, a source briefed on the investigations told Reuters.
