Service Restored After Ohio Train Crash and Explosion - WTRF 7 News Sports Weather - Wheeling Steubenville

A railroad operator says it has cleared the Columbus site of a train derailment and explosion and restored full rail service in the area.
    
Part of a train derailed early Wednesday on Norfolk Southern Corp. tracks north of downtown, and three tank cars carrying ethanol exploded, causing a fire that burned for hours.
    
Norfolk Southern says the cars have been cleared from the site, and the second of two affected main-line tracks reopened early Friday.
    
The National Transportation Safety Board is investigating what caused the crash. A board member has said the train was traveling below the recommended speed before the crash, and its operators noticed no problems with the track as they approached the curve where it happened.
    
The full investigation could take up to a year.
