Winter storm slows rail traffic

Winter storm slows rail traffic Norfolk Southern Corp. on Sunday invoked force majeure for winter weather conditions in the Upper Midwest region that it said would delay shipments.
   Snow and ice conditions are expected to prevail through Monday in the same area hit hard by a snowstorm last week.
   Rail traffic through Chicago; Elkhart, Ill.; and Toledo, Ohio; will be subject to force majeure, the railroad said. Force majeure means the railroad is absolved from any responsibility for the delays, loss or damage due to conditions out of its control.
