1769

Scottish mechanical engineer James Watt patents his design for the first practical steam engine, paving the way for the mechanized production of the Industrial Revolution.


1825

In England, George Stephenson engineers the world's first railway locomotive. Based on Stephenson's years of experimentation with steam-driven vehicles (the first of which he built in 1814), the Locomotion pulls coal on a nine-mile track.


1830

1841

The first settlers move westward across the Northern Great Plains on what will come to be known as the Oregon Trail, soon a conduit for emigration.

October 1864

Union Pacific crony Herbert M. Hoxie wins the Union Pacific construction bid, then signs the contract over to Durant's new company, Credit Mobilier. The move allows Durant to pay himself for construction, generating giant profits without congressional oversight.

January 20, 1865

President Abraham Lincoln asks Massachusetts senator Oakes Ames to help manage the Union Pacific Railroad. Oakes Ames soon invests in Credit Mobilier and promotes its interests in Washington, D.C.

Around the same time, contractor Charles Crocker convinces Central Pacific foreman James Harvey Strobridge to try Chinese workers as a means of expanding their labor force, which at this time numbers just a few hundred Irishmen.


April 9, 1865

Robert E. Lee surrenders to Ulysses S. Grant. The Civil War ends. Masses of soldiers demobilize, many of whom will soon move west. The Union Pacific has yet to spike a rail.

Five days later, on April 14, President Lincoln is assassinated. His body will be carried back to Illinois by rail, on a special Pullman car.


July 10, 1865

With Durant's activities facing increased scrutiny in D.C., the first rails of the Union Pacific line are spiked in Omaha.

Casement and his crews pass the 100th Meridian line on the prairies of Nebraska, guaranteeing the Union Pacific the irrevocable right to continue westward, as stipulated in the Pacific Railroad Act. Durant throws a grand "100th Meridian Excursion" for dignified guests, featuring a mock Pawnee ambush.


November 1866

North Platte, Nebraska sits at the end of the Union Pacific line, and soon features a potent combination of saloons, prostitutes, and criminals. This assemblage and the others like it that follow the westward press of empire are named "Hell on Wheels" towns.


December 21, 1866

Upset by increased military presence in the Powder River Valley, the most sacred and fertile hunting ground remaining in their possession, a group of Sioux warriors draws cocky Captain William J. Fetterman and his troops into a deadly ambush on the Bozeman trail.


Winter 1867

British chemist James Howden begins manufacturing nitroglycerin on-site in the mountains for the Central Pacific, eliminating the dangers of transporting the compound.


May 1867

Led by the Ames brothers, officers of the Credit Mobilier remove Durant from the Union Pacific presidency. Thus begins a flurry of legal action initiated by Durant against both Credit Mobilier and the Union Pacific, even though he continues to exert nominal leadership over both companies.


June 25, 1867

Summit work in the Sierras grinds to a halt as Chinese workers strike for better wages and shorter hours. Crocker and Strobridge cut off food, supplies, and communication to the Chinese camps. One week later, the men will go back to work at the same wage.


July 4, 1867

Dodge founds the town of Cheyenne in Wyoming Territory. Intended as a transfer point on the Union Pacific line, it will contain the company roundhouse and a military station. The company divides and sells lots to encourage emigrant settlement. By year's end, the settlement's population will exceed 4,000.

Red Cloud
November 6, 1868

After months of skirmishes known as "Red Cloud's War," the government suggests a treaty, but Native American leader Red Cloud will not condescend to meet until the military have removed themselves from the Bozeman Trail. They agree, and Red Cloud signs the Powder River Treaty, which guarantees the Sioux their massive hunting ground in perpetuity. Red Cloud is thus considered the only native leader to have won a war with the United States.


January 1869

Corinne, Utah is founded. It is the first non-Mormon settlement in the Territory; it will prove to be the last true Hell on Wheels town.


April 8, 1869

After months of increased tension, closed-door Washington lobbying, Congressional pressure, and aborted meetings between the two companies, Dodge and Huntington settle upon a meeting place for their two lines.

Victory Day
April 28, 1869

Victory Day. Charles Crocker decides he has one last thing to show the Union Pacific and the world. In a remarkable feat of strength and organization, his Central Pacific crews lay an unheard-of 10 miles of rail between sunrise and sunset.


May 6, 1869

As Pullman cars move westward toward Promontory Summit, unpaid tie workers block the line and a bridge washes out at Devil's Gate. These developments delay the arrival of Durant and Union Pacific dignitaries by two days.

Despite the delay, jubilees proceed as planned in cities throughout California on May 8. At the Central Pacific ceremony in Sacramento, toasts are raised to the pioneering visions of Asa Whitney and Theodore Judah.


May 10, 1869

Amidst a crowd of dignitaries and workers, with the engines No. 119 and Jupiter practically touching noses, the Central Pacific and Union Pacific railroads join together. Telegraph operators transmitting to both coasts transmit the blows of the hammer as they fall on a golden spike. The nation listens as west and east come together in undivided union.


September 4, 1872

During a heated presidential campaign, the Credit Mobilier scandal erupts in the press, smearing the name of many established government figures who purportedly sold their influence for Credit Mobilier stock. Among them is Speaker of the House James G. Blaine of Maine, who suggests an investigating committee will find the allegations worthless.


February 1873

A Congressional committee investigates the Credit Mobilier. The scandal creates public disillusionment with elected leaders, but the committee hands out very little punishment. All major players escape unscathed, save scapegoat Oakes Ames, who is voted out of Congress and leaves Washington in shame. He will die just months later.

1880

By this time, the Pacific railroad carries $50 million worth of freight annually. It has served as artery for 200 million acres of settlement between the Mississippi and the Pacific. The Plains Indians have been scattered to reservations, and little over 1,000 buffalo remain of the millions that once populated the grasslands. A trip between San Francisco and New York, which once might have occupied six grueling months, now takes a few days.


1882

Ignoring the crucial role Chinese immigrants played in constructing the California infrastructure, Congress passes the Chinese Exclusion Act, banning further immigration of Chinese laborers into the United States for a period of 10 years.
