OSAKA -- An early morning train run was canceled between Hineno and Otori stations on West Japan Railway's Hanwa Line at 6:04 a.m. after a 34-year-old conductor overslept, officials at Hineno Station said.The conductor, who was not named, finished his duties the previous day around midnight and went to bed in a facility near the station, the officials said.The conductor reportedly told officials he woke up once when the air cushion in the bed he was sleeping on, designed as a wake-up timer, was inflated, but then fell asleep again. The conductor overslept by several minutes until the deputy station master came to wake him up, the officials said. About 30 passengers were kept waiting about 10 minutes for the train to leave Hineno Station. The cancellation of the first train run inconvenienced about 3,500 passengers on connecting trains.
