This summer, I had the privilege to witness UP 4014, Union Pacific's restored "Big Boy" 4-8-8-4 steam locomotive, ply the rails of the UP mainline once again, this time leading the "Heartland of America" tour through the states of Wyoming, Nebraska, Iowa, Illinois, Missouri, Arkansas, Texas, Oklahoma, Kansas, and Colorado. My portion of the trip consisted of traveling to Grand Island, NE and chasing it back east towards Chicagoland and eventually Momence, IL, where I gave up the chase. This was my final shot of the chase. After making a service stop just north of the Kankakee River in Momence, IL, 4014 trundles across the second of two bridges spanning the river. A great end to the chase! Till next time, Big Boy.
