UP 4014, the Big Boy, cruises through the corn fields of eastern Iowa as it approaches the town of Grand Mound. 4014's itinerary today is traveling from Cedar Rapids, IA to Rochelle, IL where it'll be on display for the weekend. The Big Boy always brings the crowds trackside and the "Heartland of America" Tour was no exception. We fought clouds pretty much the entire day, but thankfully there were some well timed sucker holes!
