Bullet train stops after tablet PC catches fire, singes table
A shinkansen made an emergency stop Sunday after a tablet computer apparently owned by a passenger caught fire while the train was en route to Tokyo Station, police and railway officials said.
The incident aboard the Nozomi 234 super express took place at around 5:30 p.m. between Shin-Yokohama and Shinagawa stations when the tablet began spewing smoke after being turned on by its owner, who was described as a man in his 40s.
