A jumbo hopper car can carry about 100 tons of cargo, or 3,500 bushels, which equates to roughly 200,000 pounds. A 125-ton freight car can carry 125 tons, or about 4,450 bushels, which equals about 250,000 pounds. The train is capable of traveling at higher speeds, and a truck must wait at a crossing, while the train always has the right of way.
