Police say driver error caused an explosive derailment of a CSX freight train near Baltimore last month.
A preliminary report on the train derailment in Rosedale says stop signs at a rail grade crossing were faded and displaced.
Federal investigators have finished work at the railroad crossing of last month’s train derailment and are still trying to arrange an interview with the driver whose truck was hit by the CSX train.
Train operator CSX Transportation on Wednesday pointed to a hazardous chemical in a rail car as the source of an explosion on a derailed train near Baltimore that sparked a fire, rattled homes and damaged buildings. A company spokesman said officials still weren’t sure what caused the sodium chlorate to explode in the first place, but it ignited another chemical in a second car.
