COLUMBUS - The world's only operating Big Boy locomotive made its way to Columbus on Friday as part of a tour across the Midwest.

Union Pacific's Big Boy steam locomotive No. 4014 is touring the Union Pacific railway system to celebrate the 150th anniversary of the transcontinental railroad. UP says that the train engine's return to the rails is the result of over two years of restoration work by the Union Pacific Steam Team.

Big Boy hit a bit of a snag in its tour recently, as the original route was to be the rail line along Highway 30, with a stop planned in Gibbon on Thursday. However, major flooding in the Gibbon area caused travel plans to be altered, as the steam engine stopped in Kearney instead, and ended up spending the night in Grand Island. 

Other stops on Friday included Central City and Fremont, with Big Boy ultimately ending up in Omaha as a part of Omaha Railroad Days this weekend. The tour is scheduled to continue until August 8th, with stops planned in states such as Iowa, Minnesota, Wisconsin, and Illinois.

Big Boy will travel back across Nebraska to close out its trek, with another stop in Columbus scheduled for Sunday, August 4th from 11:45 AM - 12:30 PM at the 21st Avenue crossing.
