Shares of the leading short-line railroad, Genesee & Wyoming, Inc. (NYSE:GWR), rose 26.5% in the third quarter after the announcement of a transformational acquisition. Genesee purchased its primary competitor, RailAmerica, for $2 billion. The combined entity makes Genesee & Wyoming the dominant regional operator in the U.S. The acquisition also positions the company as a key U.S. industrial recovery play.
