NAGOYA (Kyodo) A suspicious object on a train in Aichi Prefecture that was later confirmed to be a radio device left behind by a passenger caused a three-hour disruption Sunday evening on Nagoya Railroad Co.'s Komaki Line, police and railway officials said.
It took about three hours after the object was found and taken off the train to determine it was a ham radio Morse code transmitter, which a 47-year-old company employee left behind on his way home after attending an amateur radio event in western Japan, the police said.
After receiving a passenger report shortly past 8 p.m. that a suspicious bag was on the four-car train bound for the city of Inuyama from Nagoya, railway officials moved it to nearby Kasugai Station and called the police, they said.
This led to the disruption of 25 train runs between Komaki and Nagoya from around 8 p.m. to 11:15 p.m.
