4. Revolutionizing Agriculture
The advent of railroads in the 19th century transformed American agriculture by providing efficient transportation for perishable goods. Refrigerated railcars, introduced in the 1860s, enabled farmers to ship fresh produce, meat, and dairy products over long distances without spoilage. This innovation expanded market reach, allowing consumers nationwide to access a diverse array of fresh foods year-round. Consequently, refrigerated railcars played a pivotal role in the growth of agribusinesses and the diversification of the American diet. (pbs.org)
