The confirmed death toll in the Japanese rail crash topped 100 today.
The toll was set to rise as rescue workers desperately tried to recover bodies still inside a crushed train car.
Using heavy equipment, workers tore holes in the carriage and extracted several bodies, bringing the official toll to 104. One body appeared to be that of the train driver (23).
The remaining bodies are in the front carriage of the train, embedded in the ground-floor car park of a nine-storey apartment building. The car has been crushed to less than half of its original length of about 20 metres.
It is thought about 10 bodies are contained inside it.
Rescue teams have been using ultrasound equipment and other high-tech gear to check for heart beats and breathing, but there was no sign of life and no survivors have been found since early on Tuesday when three people were pulled from the wreckage.
Investigators have yet to conclude why the packed commuter train jumped the tracks on the outskirts of the western city of Osaka on Monday and smashed into the apartment complex, but excessive speed appears to have played a role.
The driver of the train, who had 11 months' experience, had overshot the previous station by about 40 metres, putting the train more than a minute behind schedule.
Media have said the pressure put on train drivers by operator West Japan Railway Co. (JR West) may have contributed to the accident, which also injured 458 people, many seriously.
The driver of the derailed train had also over-shot a station by 100 metres last June and may have been worried that he would be punished, media reports and analysts said.
