Readers of this space know that the railroad sector is one of the preferred sectors. After decades of unconscionable neglect, U.S. railroads are experiencing a resurgence, propelled by international trade and the rail's cost advantage over truck transport. But as one knows, trains don't always roll, sometimes they have to brake to stop, and that's where Westinghouse Air Brake Technology makes its money.

Westinghouse Air Brake Technologies (NYSE: WAB), known as Wabtec, manufactures braking equipment and other parts for locomotives, freight cars, and passenger rail cars.

Products of Wabtec's freight group include air brake systems, draft gears, hand brakes, slack adjusters, heat exchanges, railroad electronics, and monitoring and control equipment. The company also builds new locomotives up to 4,000 horsepower and provides aftermarket services, including locomotive and freight car fleet maintenance.

Analysts expect strong, double-digit revenue growth on solid back-orders and new business. Analysts also like Wabtec's blue-chip clientele, decent pricing power, demonstrated ability to deliver products and services on time, and reasonable cost structure. The Reuters F2008/F2009 EPS consensus estimates for WAB are $2.53/$2.81.
