I don't think the railcars are carrying fermented grain, they carry grain which spills and ferments... However getting grain to ferment is somewhat tricky compared to fruit, you need the right amount of water at the right time to get it to malt and then ferment so I'm surprised there's enough of it. Just surprising, not doubting it happens. I assume the spills are from hoppers with worn out chutes, because I would not expect open hoppers for grain transport.
