This is Ray McCarthy with the news. Reports are coming in of a major train crash in Japan. A passenger train carrying hundreds of workers home from the centre of Tokyo is reported to have hit an oncoming goods train. Both were traveling at high speed. Figures are not yet available but it is believed that the death toll could be as high as 300, with hundreds more injured. Emergency and rescue services rushed to the scene. But our reporter says it will take days to clear the track and to establish the numbers of the dead and injured. There was a similar accident on the same stretch of track four years ago.
    There was another bomb scare in a large London store last night during late night shopping. Following a telephone call to the police from an anonymous caller, hundreds of shoppers were shepherded out of the store while roads in the area were sealed off. Police dogs spent hours searching the store for a bag which the caller claimed contained 50 pounds of explosives. Nothing was found and the store was given the all-clear by opening time this morning. A police spokesman said that this was the third bomb scare within a week and that we should all be on our guard.
    And finally, the motoring organisations have issued a warning to drivers following the recent falls of snow in many parts of the country. Although the falls may be slight, they say extra care is needed.
