A 9-year-old girl was killed at Coledale last night when she was struck by a southbound passenger train.Ambulance paramedics, police and Fire and Rescue NSW crews from Coledale, Bulli and Thirroul rushed to Coledale Railway Station shortly before 7pm following calls of a child trapped under a train.Emergency crews attempted to free the young girl but she was pronounced dead at the scene.Around 100 passengers on the train waited onboard for more than one-and-a-half hours while emergency service crews attended the incident.Other South Coast trains on the track at the time were also halted.Early reports indicate the child, believed to be from Coledale, may have been hit by the train while she was playing with a visiting friend below the Cater St Bridge at the southern end of the station.A NSW Ambulance spokesman said both girls had been attempting to run off the tracks when the child was hit by the oncoming train.Moments after emergency crews arrived, the child's mother reached the scene where she was comforted by police officers.South Coast line trains between Waterfall and Thirroul were immediately suspended and buses called in to transport passengers.Last night CityRail were unable to provide information on when the line would reopen and advised long delays were expected.Investigations into the child's death are continuing and police will now prepare a report for the coroner.
