Bailey Yard is halfway between Denver and Omaha. It covers a total expanse of 2,850 acres (4.45 sq mi; 11.5 km2) and is over 8 miles (13 km) in length and 2 miles (3.2 km) wide at its widest point; the facility is about 1,000 yards (910 m) wide on average. Bailey Yard has 200 separate tracks totaling 315 miles (507 km) of track, 985 switches, 766 turnouts, and 17 receiving and 16 departure tracks. Union Pacific employs more than 2,600 people in North Platte, most of whom are responsible for the day-to-day operations of Bailey Yard.
An average of 139 trains and over 14,000 railroad cars pass through Bailey Yard every day. The yard sorts approximately 3,000 cars daily using the yard’s two humps. The eastbound hump is a 34 foot (10 m) tall mound, and the westbound hump is 20 feet (6.1 m) high. These are used to sort four cars per minute into one of the 114 “bowl” tracks — 49 tracks for the westbound trains, and 65 for eastbound. The bowl tracks are used to form trains headed for destinations across North America, including the East, West and Gulf coasts of the United States, and Canadian and Mexican borders.
The yard also includes 3 locomotive fueling and servicing centers called eastbound run thru, westbound run thru, and a service track that handles more than 8,500 locomotives per month, a locomotive repair shop that can repair 750 locomotives monthly, and a car repair facility that can handle nearly 50 cars daily. The car repair shop replaces 10,000 wheel-sets each year.
