In 1970, Tropicana orange juice was shipped as finished goods via refrigerated boxcars in one weekly round-trip from Florida to Kearny, New Jersey. By the following year, the company was operating two 65-car unit trains a week, each carrying around 1 million US gallons (3,800 m3) of juice. The “Great White Juice Train” (the first unit train in the food industry, consisting of 150 100-ton insulated boxcars fabricated in the Alexandria, Virginia shops of Fruit Growers Express) commenced service on June 7, 1971 over the 1,250-mile (2,010 km) route. An additional 100 cars were soon incorporated into the fleet, and small mechanical refrigeration units were installed to keep temperatures constant on hot days. In 2004, Tropicana’s rail fleet of 514 cars traveled over 35,000,000 mi (56,327,040. 0 km) – a method that is three times more fuel efficient than other shipping methods.
