Authorities continue to investigate the upheaval of five Ohio Central Railroad cars carrying loads of coal from the Buckingham Coal Company in Gloucster to the Oxford Mining Company on Tunnel Hill Road in Perry County. Witness Sandy Rosser says she watched from behind railroad gates as one car jumped the track and rose into the air, followed by sparks caused by metal friction. OHCR officials say they've never experienced anything like this on the railway along Tunnel Hill Road. Perry County EMA Public Information Officer Jay Stephenson says authorities will continue to investigate what caused the derailment. Until then, traffic will be routed away from the crumpled railroad tracks along Tunnel Hill Road for an undetermined amount of time.
