Investigating Spain's train crash
Spain is in mourning over the deaths of 78 people in a high-speed train crash on Wednesday.
More than 90 passengers out of 218 on board the train that crashed outside Santiago de Compostela remain in hospital, including some 30 critical.
There are reports that the train was travelling at more than double the speed limit at the time of the crash, in one of Spain's worst ever rail disasters.
The driver has been formally detained, Spanish police say.
Tim Willcox visits the industrial yard where investigators will examine the engines and carriages of the train wreckage in order to ascertain what caused the crash.
