Over on CAPS, some 96% of the 197 All-Star members who have rated Norfolk Southern believe the stock will outperform the S&P 500 going forward. These All-Star bulls include sandvig and stanton17, both of whom are ranked in the top 10% of our community.

In August 2007, sandvig noted that Norfolk Southern generates "strong cash flow in what is supposed to be a weak economy. What will happen when things pick up? The economics of this industry look pretty good for the long haul."

A more recent pitch from stanton17 in August of this year shares that sentiment, quoting a recent report by Barron's to support the stock's bull case:

The U.S. Chamber of Commerce sees freight railroad use jumping 88% over the next 25 years.

"'All the evidence is there that the train is returning to a degree once never expected [and that] an economic and cultural tsunami is about to transform the United States,' says Harvard professor John Stilgoe, author of the recently published book Train Time. 'Change is everywhere along the railroads....Track is being expanded, modernized and relaid, and once-abandoned rail right-of-ways are being reclaimed. And what you are seeing now is only the beginning. The best is yet to come.'"
