Warrent Buffett, investor extraordinaire, just bought something. The Burlington Northern Santa Fe Railroad Company (BNI). It cost $26 billion. He already owned part of the railroad, but he wanted it all. Figured it was a great investment. So why should you care?

First, because it's Warren Buffett. While he's made one or two bad investments (see Eastern Airlines (who?) as an example), most of what Mr. Buffett buys increases in value. He's not the second richest man in America because he's lucky. When he buys into an industry, it may be one that most investors should consider.

This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"Obama is expected to create a national infrastructure reinvestment bank to expand and enhance existing federal transportation investments; our pick to benefit is Ingersoll Rand (NYSE: IR)," says Thomas Vass in The Technology Stock Advisor.

"The national infrastructure reinvestment bank will receive an infusion of federal money, $60 billion over 10 years, to provide financing to transportation infrastructure projects across the nation.

"These projects will create up to two million new direct and indirect jobs per year and stimulate approximately $35 billion per year in new economic activity.

"The one area in particular that will benefit the most from the new national infrastructure reinvestment bank is the the industrial machinery and distribution equipment value chain.

"This sector has the potential income and employment multiplier effects to create the jobs Obama is promising as a result of this policy.

"Within that sector, Ingersoll Rand has the best prospects for stock price appreciation. It is rated an A stock by S & P for quality. Our target buy price on the stock is $37. The target sell price is $56."
