(PAULSBORO, N.J.) -– Investigators are working to find the cause of a train derailment in southwestern New Jersey, which in turn caused a bridge to collapse Friday morning.
Three cars had been leaking possibly hazardous material.
Eighteen people were sent to the hospital after complaining of breathing difficulties. Nearby residents were evacuated and schools placed on lockdown as a precaution.
The site has now been deemed safe. Cleanup of the wreck is expected to take several days.
