Reference excerpt

The history of the Union Pacific Railroad stretches from 1862 to the present. For operations of the current railroad, see Union Pacific Railroad; for the holding company that owns the current railroad, see Union Pacific Corporation. There have been four railroads called Union Pacific: Union Pacific Rail Road, Union Pacific Railway, Union Pacific Railroad (Mark I), and Union Pacific Railroad (Mark II). This article covers the Union Pacific Rail Road (UPRR, 1862–1880), Union Pacific Railway (1880–1897), and Union Pacific Railroad (Mark I)(UP, 1897–1998). For the history of the Union Pacific Railroad (Mark II), see Union Pacific and Southern Pacific Transportation Company.

Beginnings: 19th century The original company, Union Pacific Rail Road (UPRR), was created and funded by the federal government by Pacific Railroad Acts of 1862 and 1864. The laws were passed as war measures to forge closer ties with California and Oregon, which otherwise took six months to reach. UPRR remained under partial federal control until the 1890s. Its management was noted for many feuds and high turnover. The UPRR main line started in Council Bluffs, Iowa and moved west to link up with the Central Pacific Railroad line, which was built eastward from Sacramento. Construction on the UPRR main line was delayed until the American Civil War ended in 1865. Some 300 miles of main line track were built in 1865–66 over the flat prairies. The Rocky Mountains posed a much more dramatic challenge but the crews had learned to work at a much faster pace with 240 miles built in 1867 and 555 miles in 1868–69. The two lines were joined in Utah on May 10, 1869, hence creating the first transcontinental railroad in North America. Interstate 80, built in the 1950s, paralleled the UPRR main line. In 1870 the fare in coach from Omaha to San Francisco was $33.20 ($845.30 in 2025), with sleeper cars costing extra. The train stopped for meals at lunch rooms along the way. Passenger traffic for the long trip was light at first—2,000 a month in the 1870s, growing to 10,000 a month in the 1880s. Wall Street speculator Jay Gould (1836–1892) took control of the UPRR in 1874, as well as the smaller Kansas Pacific Railway based in Kansas City. He merged the two into the Union Pacific Railway in 1880, giving the Union Pacific new markets in the wheat and ranching regions of Kansas and eastern Colorado. Branches were opened to mining districts in Montana, Idaho, and Utah and (until 1893) to farmlands in Oregon. Despite severe austerity measures the Union Pacific was unable to repay its old government loans. Most of the wheat farmers joined the People's Party, a Populist movement in the 1890s and engaged in heated anti-railroad rhetoric. The Populists were soon voted out and had no lasting impact on the Union Pacific. In the Panic of 1893 financial crisis the Union Pacific Railway, like 153 other American railroads, went bankrupt. The trains continued to operate but the bondholders lost their investment. In 1897, a new Union Pacific Railroad (UP) was formed and absorbed the Union Pacific Railway; this new railroad reverted to the original Union Pacific name of the original company but now pronounced "Railroad" and not "Rail Road". Empire builder E. H. Harriman (1848–1909) purchased the UP for a song. He upgraded its 3,000 miles of trackage, modernized its equipment and merged it with the Southern Pacific, which dominated California. The Supreme Court broke up the merger in 1910. From 1910 to 1980, there was little growth in the UP, which dominated the farming, ranching, mining and tourist trade in a region stretching from Omaha and Kansas City in the East, to Salt Lake City and Denver in the West. Economically, the UP provided transcontinental service, as well as shipping out wheat and other crops, cattle, and mining products and bringing in consumer items and industrial goods from the East. There was little expansion 1910–1980 but after that the UP system grew to over 32,000 miles (51,000 km) of track with large lines like the Southern Pacific, the Missouri Pacific Railroad and the Missouri–Kansas–Texas Railroad becoming part of the UP system as well as smaller ones.

Finances

The UPRR main line was completed in 1869, at a cost of $109 million ($2.64 billion in 2025). About $50 million was spent on the construction work. The rest included a profit of about $13–16 million to the owners, possibly several million dollars in bribes to Congressman and especially heavy discounts in the sale of bonds of a railroad that most investors thought would never make a profit. The original UPRR was entangled in the Crédit Mobilier scandal, exposed in 1872. Its independent construction company, the Crédit Mobilier, had bribed congressmen. The UPRR itself was not guilty but it did get bad publicity. The Panic of 1873 another financial crisis, led to financial troubles but not bankruptcy. Jay Gould took control in 1873 and built a viable railroad that depended on shipments by local farmers and ranchers. Gould immersed himself in every operational and financial detail of the system. He built up encyclopedic knowledge, then acted decisively to shape its destiny. "He revised its financial structure, waged its competitive struggles, captained its political battles, revamped its administration, formulated its rate policies and promoted the development of resources along its lines.". Gould created the new Union Pacific Railway and merged the original UPRR, the Union Pacific Rail Road, into the new Union Pacific Railway.

After Gould's death, the Union Pacific Railway slipped and declared bankruptcy during the Panic of 1893. Yet in November 1897 the national economy was quickly reviving and profitability was at hand. An agreement was reached to pay the US Treasury the entire amount of principle and accrued interest on the bonds. The government received every dollar it wanted from the Union Pacific. In 1897, a new Union Pacific Railroad (UP) was formed and absorbed the Union Pacific Railway, this new railroad reverted to the original Union Pacific name of the original company but now pronounced "Railroad" and not "Rail Road". E. H. Harriman bought the line cheaply, and made it much more efficient and highly profitable. He tried to incorporate it into a vast western system but the Supreme Court blocked his attempts as monopolistic.

Worked examples

Example 1 — a first encounter with History of the Union Pacific Railroad

Start with the simplest possible case. Write down what History of the 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 History of the 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 History of the 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 History of the Union Pacific Railroad

In research: History of the 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 History of the 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: History of the Union Pacific Railroad is common in secondary-school and first-year university syllabi. It links to neighbouring topics American companies established in 1862, Arizona railroads, Arkansas railroads, so understanding it makes those chapters shorter.
In everyday life: Look for History of the 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.
