I understand it. You love railroads, but those pricey multiples just don't get your motor running. My sympathies. I've had it out for Warren Buffett, Berkshire Hathaway's (NYSE: BRK-A) (NYSE: BRK-B) wunderkind, since he first took stock of Burlington Northern Santa Fe. Maybe it wasn't his doing, but the stocks have never looked cheap.

Well, that's changed, but not because the sector's taken pity on our poor souls. RailAmerica (NYSE: RA), a Fortress (NYSE: FIG) leveraged buyout, was taken public again just about a year ago, and with it, we've the keys to a veritable value trifecta. It's actually more than a value trifecta -- but the word trifecta's just tickling to say and write. With monopoly assets, recently righted operations, and room to run in its turnaround, RailAmerica's a train that's likely to keep a-rollin'. And that's just why I've bought it for my Rising Stars portfolio. Come join me on my discussion board, or read my original write-up here.
