Union Pacific Railroad

Union Pacific Railroad is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Union Pacific Railroad rather than just read about it. In short: The Union Pacific Railroad Company (reporting marks UP, UPP, UPY) is a Class I freight-hauling railroad that operates 8,300 locomotives over 32,200 miles (51,800 km) routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second-largest railroad in the United States after BNSF.

Key takeaways

  • Union Pacific Railroad belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Union Pacific Railroad to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Union Pacific Railroad from memory before moving on to harder problems.

Reference excerpt

The Union Pacific Railroad Company (reporting marks UP, UPP, UPY) is a Class I freight-hauling railroad that operates 8,300 locomotives over 32,200 miles (51,800 km) routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second-largest railroad in the United States after BNSF. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1995, the Union Pacific merged with Chicago and North Western Transportation Company, completing its reach into the Upper Midwest. In 1996, the company merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad. The Union Pacific Railroad Company is the principal operating company of Union Pacific Corporation, which are both headquartered at the Union Pacific Center, in Omaha, Nebraska. Union Pacific has announced plans to acquire the Norfolk Southern Railway in a deal worth $85 billion. If approved by regulators, it would create the first transcontinental railroad network in the United States.

History

Union Pacific in the 19th century

The original company, the "Union Pacific Rail Road", was incorporated on July 1, 1862, under the Pacific Railroad Act of 1862. President Abraham Lincoln had approved the act, which authorized railroad construction from the Missouri River to the Pacific to ensure the stability of the Union throughout the American Civil War, but construction was not completed until after the conflict's conclusion. Under the original bill that formed the basis of the 1862 Pacific Railroad Act, the Union Pacific Railroad was to be built from the Nevada–Utah border in the west to the Colorado–Kansas border in the east. However, due to intense lobbying by Dr. Thomas Clark Durant, the eastern terminal was moved to a location where the Union Pacific could link up with the Mississippi and Missouri Railroad in Iowa. Following the Act's passage, commissioners appointed by Congress began selling stock in the federally chartered Union Pacific Railroad Company. By 1863, Durant had organized the purchase of 2,000 shares, the prerequisite amount of stock sold in order to begin the railroad's construction. The resulting track ran westward from Council Bluffs, Iowa, to meet in Utah the Central Pacific Railroad line, which had been constructed eastward from Sacramento, California. The combined Union Pacific–Central Pacific line became known as the first transcontinental railroad and later the Overland Route.

The line was constructed primarily by Irish labor who had learned their craft during the recent Civil War. Under the guidance of its dominant stockholder, Thomas C. Durant, the namesake of the city of Durant, Iowa, the first rails were laid in Omaha. The two lines were joined at Promontory Summit, Utah, 53 miles (85 km) west of Ogden on May 10, 1869, creating the first transcontinental railroad in North America. Leland Stanford, founder of the Central Pacific Railroad which itself eventually was merged with Union Pacific, himself drove the golden spike, inscribed with the words "to span the continent and wed the oceans."Subsequently, the UP purchased three Mormon-built, narrow-gauge roads: the Utah Central Railroad extending south from Ogden to Salt Lake City, the Utah Southern Railroad extending south from Salt Lake City into the Utah Valley, and the Utah Northern Railroad extending north from Ogden into Idaho. The UP also purchased the Utah Eastern Railroad and Utah Western Railroad, both Mormon narrow-gauge lines. The original UP was entangled in the Crédit Mobilier scandal, exposed in 1872. As detailed by the New York Sun, Union Pacific's largest construction company, Crédit Mobilier, had overcharged Union Pacific; the railroad would then pass the inflated costs on to the United States government. To convince the federal government to accept the increased costs, Crédit Mobilier had bribed multiple congressmen. Several prominent UP board members (including Durant) had been involved in the scheme. The ensuing financial crisis of 1873 led to a credit crunch, but not bankruptcy. As boom followed bust, the Union Pacific continued to expand. A new company, with dominant stockholder Jay Gould, purchased the old on January 24, 1880. Gould already owned the Kansas Pacific (originally called the Union Pacific, Eastern Division, though in essence a separate railroad), and sought to merge it with UP. Through that merger, the original "Union Pacific Rail Road" transformed into "Union Pacific Railway". Extending towards the Pacific Northwest, Union Pacific built or purchased local lines to reach Portland, Oregon. Towards Colorado, it built the Union Pacific, Denver and Gulf Railway: a system combining narrow-gauge trackage into the heart of the Rockies and a standard gauge line that ran south from Denver, across New Mexico, and into Texas. The Union Pacific Railway would later declare bankruptcy during the Panic of 1893. The resulting corporate reorganization reversed Gould's name change: Union Pacific "Railway" merged into a new Union Pacific "Railroad".

Worked examples

Example 1 — a first encounter with Union Pacific Railroad

Start with the simplest possible case. Write down what Union Pacific Railroad claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Union Pacific Railroad before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Union Pacific Railroad ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Union Pacific Railroad

In research
Union Pacific Railroad appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Union Pacific Railroad in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Union Pacific Railroad is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1862 establishments in Nebraska Territory, American companies established in 1862, Arizona railroads, so understanding it makes those chapters shorter.
In everyday life
Look for Union Pacific Railroad outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
