Tanker cars removed from Columbus crash site

Norfolk Southern Railorad says it has cleared the site of Wednesday's train derailment and explosion near the state fairgrounds and has restored full rail service in the area. The company says the three tank cars carrying ethanol that exploded have been removed,  and the second of two affected
main-line tracks reopened early this morning. The National Transportation Safety Board is investigating the cause of the crash. A spokesperson has said the train was traveling below the recommended speed, and its operators noticed no problems with the track as they approached the site.
