Detailed explanation-1: -He therefore hired an engineer to design a refrigerator car; the finished design circulated fresh air that was chilled by passing it over ice. In 1877 Swift successfully shipped the first refrigerator carload of fresh meat to the East.
Detailed explanation-2: -The refrigerated rail car was not simply a railroad innovation, but one significant component of centuries-long efforts to chill and preserve perishable foodstuffs.
