Federal investigators continue to look for the cause of an “El” train derailment on Chicago’s South Side yesterday morning. Fourteen passengers on the Green Line train were taken to area hospitals. None were seriously injured.
Peter Knudson is a spokesperson for the National Transportation Safety Board. He says the full investigation could take up to a year and a half.
KNUDSON: We spend about three to five days on scene. And there’s a lot of work that happens after that. It’s actually the bulk of the work, where the investigator goes back to the office and does the research, often does many interviews and may come and request more tests to be done on particular pieces of equipment.
Yesterday, the CTA released its own preliminary findings, blaming the train’s driver for the derailment. The agency is storing the train cars at a repair facility for inspection.
