PEWAUKEE, Wis. (TheStreet) -- The traders on CNBC's "Fast Money" told their viewers what they must know after Warren Buffett announced on Tuesday his largest-ever takeover of railroad company Burlington Northern Santa Fe(BNI Quote) for $26 billion. "It's an all-in wager on the economic future of the United States," Buffett said in a statement. Tim Seymour said Buffett's move is a long-term play that won't change anyone's short-term trading strategies.

Joe Terranvoa told viewers that Buffett's move is a signal to investors that he's bullish on transports, energy and infrastructure. He thinks this means good times are in store for FedEx(FDX Quote). Pete Najarian mentioned the deal makes another of Buffett's big holdings, Union Pacific(UNP Quote), attractive because of its exposure to coal. He pointed out that the Burlington deal moved up stocks in the grain, coal and fertilizer sectors.

The traders spoke to Peter Schiff, president of Euro Pacific Capital, to find out what he thought about the Buffett takeover. Schiff said the deal was basically a way for Buffett to make a big bet on commodities. He explained that if oil prices continue to move higher, trucking becomes less competitive, thereby making railroads the best choice to move raw materials. Schiff said Buffett is just trying to get out of cash and invest in inflation hedges.
