Union Pacific Railroad's Bailey Yard in North Platte, Nebraska, is the largest railroad classification yard in the world. This massive yard covers 2,850 acres, reaching a total length of eight miles, well beyond the borders of North Platte, a community of 25,000 citizens. Put end-to-end, Bailey Yard's 315 miles of track would reach from North Platte in western Nebraska east past Omaha on the Iowa border along the Missouri River. Every 24 hours, Bailey Yard handles 10,000 railroad cars. Of those, 3,000 are sorted daily in the yard's eastward and westward yards, nicknamed "hump" yards. Using a mound cresting 34 feet for eastbound trains and 20.1 feet for those heading west, these two hump yards allow four cars a minute to roll gently into any of 114 "bowl" tracks where they become part of trains headed for dozens of destinations. Together, these two yards have 18 receiving and 16 departure tracks and enough room for 2,800 football fields. Photo Jan. 2006 by Amaro Rocha.
