WASHINGTON — Three days after a train derailment in downtown Philadelphia left a load of crude oil dangling above a river, the National Transportation Safety Board on Thursday recommended strict new safety measures for transporting crude oil by rail.
The NTSB’s recommendations to the US Department of Transportation grew out of earlier accidents — notably the disaster last July in Lac-Megantic, Quebec, when an unattended 74-car train derailed after a downhill run into town, killing 47 people in an explosion and fire. But the potential crisis in Philadelphia might have been avoided under the NTSB proposal.
