On CAPS, 97% of the 1,166 members who have rated Norfolk Southern believe the stock will outperform the S&P 500 going forward.  

Just last week, one of those Fools, All-Star JaysRage, highlighted the tailwinds working in the stock's favor:

I think railroads are extremely under-valued right now, and they are positioned to do extremely well in the current economic environment. With gas prices under extreme pressure, railroads provide an excellent cost-competitive logistical option for shipping. In addition, railroads are a key part of the global logistical marketplace. International manufacturers are more frequently using the rail to get their products from coastal ports inland as part of their logistical networks. Any sort of real global economic recovery (we're not there yet), and the rail networks would have some real nice pop in profitability. ...

This is a nice solid core holding for a long-term portfolio, and it's a great buy right now, for most portfolio types.
