Who invented the railroad refrigerator car?
Gustavus Swift
1878: Gustavus Swift (along with engineer Andrew Chase) developed the first practical ice-cooled railcar. Soon Swift formed the Swift Refrigerator Line (SRL), the world’s first. 1880: The first patent for a mechanically refrigerated railcar issued in the United States was granted to Charles William Cooper.
Who invented refrigerated railroad cars first using ice and later electricity?
In the late 1930s, at the request of the Werner Transportation Company, Minneapolis (Minnesota) engineer Frederick McKinley Jones (1892–1961) sought ways to build an automatic, ice-free air-cooling unit for long-distance trucking.
Why was the refrigerated railroad car invented?
Refrigerator cars, also commonly referred to by their shortened name as “reefers” were a revolutionary design that allowed for the widespread shipment of perishable food products such as dairy, meat, and vegetables. The earliest such cars date back to the mid-19th century, naturally using ice as a means of cooling.
Are there refrigerated rail cars?
According to the Association of American Railroads (AAR), in any given year, railroads ship approximately 65,000 carloads of fresh fruits and vegetables and 74,000 carloads of meat and poultry products. With the help of refrigerated rail cars (also known as “reefers”).
Who invented refrigerator?
1740s. The first form of artificial refrigeration was invented by William Cullen, a Scottish scientist. Cullen showed how the rapid heating of liquid to a gas can result in cooling. This is the principle behind refrigeration that still remains today.
How did the refrigerated railroad car changed America?
Refrigerated trucks and railroad cars have had a great impact on the economy and eating habits of Americans. As the United States became more urbanized, the demand for fresh food shipped over long distances increased. Meat products were especially in demand.
How did the refrigerated railroad car affect the business world?

How does refrigerator car work?
When the fluid is pressurized in the condenser, it heats up, releasing into the air from the outside chamber. After that, as the fluid flows into the lower pressure evaporator, the temperature turns cold. The fluid cycles between the two, keeping the cold inside while pumping the hot air out into the surrounding area.
Who invented the refrigorator?
William Cullen at the University of Glasgow demonstrated the first artificial refrigeration system in the year 1748. However, he never used his discovery for practical purposes. In the year 1805, US inventor Oliver Evans, designed the first refrigeration machine that didn’t use liquid and instead used vapor to cool.
Who was the inventor of the railroad car?
The refrigerated railroad car was patented by J.B. Sutherland of Detroit, Michigan in 1867. He designed an insulated car with ice bunkers in each end of the railroad car. Air would enter through the top of the car, passed through the ice bunkers, and circulated through the car by gravity and convection.
What is refrigerated railroad car?
A refrigerator car (or “reefer”) is a refrigerated boxcar (U.S.), a piece of railroad rolling stock designed to carry perishable freight at specific temperatures.
