The farmers felt the railroads had monopoly power over them. The farmers essentially had no choice but to send their crops to market on trains. There was not much, if any, competition on most short-line tracks that went through farm areas. Therefore, most farmers had to simply accept whatever price railroads charged to transport crops. Farmers felt the railroads could gouge them by charging high prices and that they, the farmers, had no recourse when this happened. They blamed much of their trouble on this monopoly power.
