It allowed farmers to transport fresh produce and dairy products long distances without spoilage, opened up new markets, and increased profits. The invention also played a crucial role in the expansion of the railroad industry and led to the decline of other modes of transportation.
Step-by-step explanation:
The refrigerated railway car was such an important invention because it revolutionized the transportation of perishable goods. Before its invention, it was difficult to transport fresh produce long distances without spoilage. With the refrigerated car, farmers and suppliers could now transport their goods safely and efficiently, opening up new markets and increasing profits.
For example, the invention of the refrigerated car allowed farmers to transport dairy products like milk and cheese over long distances without them going bad. It also made it possible to transport fresh fruits and vegetables to urban areas where they were in high demand.
The refrigerated car also played a crucial role in the expansion of the railroad industry, as it allowed for the transportation of a wider range of goods and increased the overall efficiency of the railway system. In addition, it led to the decline of other modes of transportation such as cattle cars and stock yards, making it more cost-effective and convenient for farmers to transport livestock.
