UP Completes Largest Rail Construction in Modern Times

An average of 100 trains a day travel the Kearney Subdivision between North Platte and Gibbon, Neb., making this run the busiest freight main line in North America. Increased coal traffic spurred the need to build a third 108-mile main line track. The four-year project eased the congestion and now carries UP-distributed power coal trains as well as other traffic. It serves the Bailey Yard in North Platte, the world’s largest classification yard.
