A Yogyakarta-bound passenger train, dubbed Senjata Utama, derailed in the Central Java town of Bumiayu early Tuesday but none of its 420 passengers was hurt, ANTARA reported. Head of the Purwokerto railway station Dariyadi, who confirmed the accident, said the derailed coaches were put back on the railway track at around 06.00. The derailment forced a Jakarta-bound executive-class train named Gajayana to stop for a while at Purwokerto railway station, he said. "Railway traffic returned to normal after the derailed coaches had been put back on the track," he said. The cause of the accident is still unknown.
