What industry did the refrigerated railcar impact the most

The answer to the question: What industry did the refrigerated railcar impact the most, would be: the food industry in general, with the meat and dairy industries, as well as the producers of fruits and vegetables, being the most benefited.

Explanation:

Before the advent of refrigeration, it was not possible for farmers to send their  products: dairy, meat, and fruits and vegetables, accross long distances because the heat would decompose them. As such, these products had to be produced locally, or not be consumed at all. So if a person leaving in Texas, wished to enjoy the dairy products of another state, or territory, they would have to travel to that place and consume the products locally. Otherwise, heat would decompose the food. But with the refrigerated railcar, this scenario changed completely and the food industry was able to reach all corners of the U.S markets.
