Indiana is home to 5,168 miles of railroads used to transport grain and other goods. Of the 51 million bushels of soybean shipped out of state, 65 percent were shipped by rail.

One thing is clear: Rail infrastructure affects farmers' bottom lines.

Poorly maintained rail lines cannot handle heavy traffic, causing detours, delays and other inefficiencies that increase the cost per mile to haul freight. These additional costs travel down the corn supply chain all the way to the farmer.
