Spanish officials are continuing their investigation into an underground train crash that killed at least 41 people in the eastern city of Valencia yesterday.
They said a wheel broke on a curve as the train approached the Jesus underground station, and two train carriages derailed in the tunnel. Another 47 people were hurt, of whom 12 remain hospitalised, two of them in critical condition.

Rescue teams worked into the night to recover the dead from inside wrecked carriages.
"There may be other bodies, forensic police are working intensively at the accident scene," said a government official.
Trapped passengers rang emergency services from mobile phones, and 150 people were evacuated from the station platform.
Officials ruled out a terror attack in a country still shaky from train bombings by Islamist militants that killed 191 people in Madrid in 2004.
"It seems this unfortunate accident was caused by excess speed and a wheel breaking just before it entered the station," a government official told Spanish radio.
Emergency services set up two field hospitals in tents on the street and a judge arrived to supervise the removal of bodies. Hundreds of people converged on the city's morgue to help identify victims.
The crash took place days before Pope Benedict is due to visit Valencia for a "World Meeting of Families", and pilgrims were already arriving in the Mediterranean seaside city.
