Cramer's 'Mad Money' Recap: Working on the Railroads

Cramer called Koppers "a subtle way" to play the railroad boom and suggested that people get aboard the stock.

Answering a call about Greenbrier (GBX Quote), Cramer told the caller he had recommended the stock off of Stockpickr.com, in the hopes that he could "bust some shorts." However, then he saw the error of his way.

Cramer said that Greenbrier is in fact a rail car play, but it is not the one he wants people to own.

Rail Safe

Another way to play the rail cycle, he said, is with Trinity Industries (TRN Quote), the largest manufacturer of rail cars in the U.S.

Trinity is a "pure play" and the "one to own," Cramer said. It is kind of a confusing stock that tends to turn people off, but if people take a closer look at it they'll see Trinity is "all about the rails," he said.

Trinity, like Koppers, has also seen a nice jump since Cramer recommended it a while back. But he believes that it should still go higher. "If this doesn't go up with the rails, nothing does," Cramer said.

Because ethanol needs to be transported by rails, Trinity, which makes ethanol rail cars, will benefit, he said. And the company also makes wind towers, which makes it a play on "Green Day."
