The Union Pacific Railroad ($ UNP), since 1862, is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago and New Orleans. The Union Pacific Railroad system is the second largest in the United States after BNSF Railway and it is one of the world’s largest transportation companies. The headquarters for Union Pacific is in Omaha, Nebraska.

The Union Pacific/Northwest Line (UP-NW) is a Metra commuter rail line maintained and operated by the Union Pacific Railroad in Chicago, Illinois and its surrounding suburbs. The Union Pacific/Northwest line are bright “Viking Yellow,” honoring the Chicago & North Western Railway’s Viking passenger train. Metra does not refer to any of its lines by colors like the CTA does, but the timetable uses colors for each line on maps and on official Twitter accounts.

Union Pacific has a local office in Elk Grove Village at 2511 Pratt Boulevard. Union Pacific also operates Proviso Yard in Northlake, Illinois (Union Pacific Railroad Global II), which was owned by Chicago and North Western Transportation Company until 1995. The Union Pacific yard is located just south of the Canadian Pacific Rail Chicago Intermodal Terminal, which is directly south of O’Hare International Airport. When traveling on I-294, the Canadian Pacific Railroad yard is located just west of I-294 and the Union Pacific Proviso yard is located just east of I-294. Global II has Container on Flat Car (COFC) capability, which is the updated version of Trainer on Flat Car (TOFC).

Hump yards are the largest and most effective classification yards, with the largest shunting capacity — often operating several thousand cars a day. The heart of these yards is the hump—a lead track on a small hill over which an engine pushes the cars. Single cars, or a block of coupled cars, are uncoupled just before or at the crest of the hump, and roll by gravity onto their destination tracks in the tracks where the cars are sorted, called the classification bowl. A classification yard is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks.

Union Pacific Global I is located at 1425 South Western Avenue, Chicago which runs along 14th Street, just east of Western Avenue. The facility is capable of Container on Flat Car (COFC).

There is an important junction of freight and passengers at the Deval Diamond in Des Plaines, located just south of the railroad bridge over Northwest Highway (US 14).

Railroad workers were assigned 48 hours of around-the-clock work to completely replace Chicago’s five-track Deval diamond. Here’s the time-lapse lesson in tenacity, technology and teamwork condensed to under two minutes.
