The death toll in the head-on crash of a commuter train and a freight train outside Los Angeles has risen to 24 and more fatalities are expected, officials said.
The Friday afternoon crash -- the worst commuter train crash in Los Angeles history -- was likely caused by the passenger train engineer's failure to stop at a red light, officials said.
'We have confirmed 24 dead and are still working to extricate bodies,' said Los Angeles Fire Department spokesman Ron Myers.

The collision also injured 135 people, including 45 who were in critical condition.
California Governor Arnold Schwarzenegger and Los Angeles Mayor Antonio Villaraigosa addressed members of the media at the scene of the derailment.
He said that the crash appeared to have been caused by human error.
'Metrolink has talked about there was some human failure there because we never know exactly, whether it was mechanical failure or computer failure or something is wrong with the tracks. They say it was human failure,' Schwarzenegger said.
Denise Tyrrell, a spokeswoman for the train line, said it was a Metrolink engineer that made the error. She said the engineer worked for a subcontractor used by Metrolink. The engineer was believed to have died in the crash.

There were 222 people on the Metrolink train, and three Union Pacific employees aboard the freight train, according to media reports.
Fire Department officials said workers were continuing efforts to extricate the bodies from the twisted wreckage.
The force of the crash pushed the locomotive engine pulling the commuter train backward into a passenger car, and both toppled over, igniting in flames. At least seven cars from the freight train derailed, although most remained standing across the tracks.
Both trains were traveling at about 40 miles per hour, according to Tyrrell.
Distraught relatives and friends of passengers awaited word on their loved ones as rescue workers delicately dismantled a crushed Metrolink passenger car in search of victims.
The search was expected to last into Sunday as firefighters dug deeper into the wreckage.
Firefighters put out a fire under part of the train and pulled people from the passenger car, which was rested on its side with the Metrolink engine shoved inside it. Two other Metrolink cars remained upright.

The train wreck shocked those who first saw it.
Leslie Burnstein heard screams of agony as she ran through a smoky haze toward a wrecked train where dozens of bloodied passengers were still trapped inside. She pulled victims out one by one, some weeping as they looked about at the destruction.
'It was horrendous,' said Burnstein, a psychologist who saw the train crash from her home. 'Blood was everywhere. ... I heard people yelling, screaming in pain, begging for help.'
Passenger Willie Castro, 67, who was in the commuter train’s last carriage, said: ‘All of a sudden we heard a big crash. Everyone flew all over the place. It was just a big crash. A boom.’
Fellow commuter Arnie Peterson, 47, said: ‘We just stopped dead and everything was flung forward.
‘There were seats and tables ripped right out of the floor.’
The engine of the Union Pacific freighter was left on its side, its nose against the Metrolink wreckage. The rest of the freight train was accordioned behind it. Fire Chief Douglas Barry said heavy equipment was brought in to take apart cars, including one that some victims still trapped inside.

'This is the worst accident I've ever seen,' Mayor Antonio Villaraigosa said. 'Clearly the injuries are going to mount and so are the fatalities.'
Marc Eckstein, medical director for the city Fire Department, said 135 people were transported to hospitals - about 85 of them in serious or critical condition.
In the initial hours after the disaster, firefighters treated the injured at three triage areas near the wreck, and helicopters flew in and out of a nearby landing area on medical evacuation flights.
Rescuers worked atop the wreckage and through breaches in the passenger car to reach victims. Dazed and injured passengers sat on the ground.
One injured man told KNBC-TV he boarded the Metrolink train in suburban Burbank and was talking with a fellow passenger when the crash occurred.
'Within an instant I was in my friend's lap. It was so quick. It was devastating,' he said.
Antonio Villaraigosa, the city’s mayor, said: ‘I am heartbroken to see this number of injuries, devastation, carnage.’

Metrolink spokeswoman Denise Tyrrell said the Metrolink train left Union Station in downtown Los Angeles and was headed northwest to Moorpark in Ventura County. The trains collided about 4:30 p.m. in the Chatsworth area of the San Fernando Valley.
'I do not know what caused the wreck,' said Tyrrell who broke down crying. 'Obviously two trains are not supposed to be on the same track at the same time.'
Union Pacific spokeswoman Zoe Richmond said it was common in California for freight and commuter trains to share the same track.

The crash happened in an area where the tracks form a 'U' shape, about 2,500 feet (760 metres) wide. At the top of the bend is a 500-foot (150-metre) long tunnel that runs beneath Stoney Point Park, popular with climbers for its large boulders.
On the north side of the tunnel, there is a siding, a length of track where one train can wait for another to pass, Tyrrell said.
The federal investigation into the crash will be headed by the National Transportation Safety Board, said Steven Kulm, a spokesman for the Federal Railroad Administration. The FRA will conduct a review of whether any federal rail safety regulations were violated.
Asked how the two trains ended up on the same track, Kulm said, 'We are nowhere near having any information on that.'

Prior to Friday, the worst disaster in Metrolink's history occurred on January 26, 2005, in suburban Glendale when a man parked a gasoline-soaked SUV on railroad tracks. A Metrolink train struck the SUV and derailed, striking another Metrolink train traveling the other way, killing 11 people and injuring about 180 others.
Juan Alvarez was convicted this year of murder for causing that crash.
