With Warren Buffett in the news recently, it is timely to look at a recent report from Paul Tracy, highlighting some of the best-positioned stocks currently held by Berkshire Hathaway (NYSE: BRK.A) -- Burlington Northern Santa Fe (NYSE: BNI) and WABCO Holdings (NYSE: WBC).

Here, the editor of StreetAuthority Market Advisor explains, "Buffett looks for such factors as intrinsic value, low debt, managerial expertise, a margin of safety and an 'economic moats' that offers some sort of sustainable competitive advantage." Here's a pair of transportation stocks that fit the bill.

"While many investors fret over the current volatility in the stock market, Warren Buffett is likely busy looking for value. Historically, in volatile up and down markets, Buffett has found even more opportunities than in raging bull markets."

"Burlington Northern Santa Fe is the second-largest railroad in the U.S. Berkshire holds an 18.2% stake in BNI, recently boosting that stake by purchasing 11 million shares to bring its total ownership to more than 63 million shares. Buffett has made no secret of his desire to purchase more of the stock.

"The key to discerning competitive advantages between the major railroad firms lies in the strategic location
of their networks. Specifically, BNI has the largest network of track in a region of the western U.S.
known as the Powder River Basin, which is home to America's largest reserves of coal.

Oshkosh Truck (NYSE: OSK) is the favorite conservative idea for 2007 from Jon Markman, editor of Strategic Advantage. "I do not expect a recession within a six-month horizon, which increases my confidence in picking a cyclical company such as Oshkosh -- especially since there is so much fear that the economy is headed straight for a recession.

"OSK -- which designs and manufactures a wide range of commercial, fire, emergency, and military trucks and truck bodies under several trademarks, including Oshkosh, Pierce, McNeilus, Medtec, Jerr-Dan, BAI, London, and Geesink -- is now cheap on every valuation measure that I consider important.

"The stock has fallen about 35% from its May highs in recent weeks. Investors were worried about its future growth rate, and there has been some skepticism about a large acquisition that was announced a month ago.

"Moreover, next year it will likely qualify as one of my Core Select List stocks, as it has provided positive earnings, revenue, cash flow, and capital appreciation for the past nine years straight. The company earns a high return on capital, and is one that I believe you can own for years. You should start buying OSK for a late 2007 target of $67 and a $95 target for 2009."
