Connecting a continent

As the United States economy industrialized in the 19th century, there were two ways to get goods and people from the east to the other side of the continent: either load huge freight wagons for a rigorous journey over treacherous mountains before reaching the West Coast, or travel by boat around the tip of South America.

Industrialist Leland Stanford is credited for organizing an idea to build a new railroad infrastructure that would connect the still-young nation. So it was that Congress passed the Pacific Railroad Act in 1862, guaranteeing public land grants and loans to the Central Pacific and the Union Pacific railroads. Work began in 1866 from Omaha and Sacramento, and on May 10, 1869, in Promontory, Utah, the "golden spike" was driven connecting the two rail lines.

The connection bridged the 2,000 miles to the Missouri River, and the passage to the West was reduced to just six days.

The Jupiter locomotive

Jupiter of the Central Pacific Railroad was one of the locomotives that met in the 1869 Golden Spike Ceremony in Utah, marking completion of America's first transcontinental railroad.

The American rail network did not run coast to coast until June 4, 1876, when a train named the Transcontinental Express arrived in San Francisco 83 hours and 39 minutes after it left New York City.

Meeting of the two railroads

Here, you can see the meeting of the two railroads and the different kinds of ties used. The theory is that the ties from the West were superior due to the prevalence there of saw mills and abundant lumber.

Who could lay the most track in a single day?

During the final weeks of the project to complete the Transcontinental Railroad, the crews working on each side competed to see who could lay the most track in a single day.

"In early April (1869), the Union Pacific laid 8.5 miles of track in one day," reads a National Park Service brochure. "The (Union Pacific) then bet the Central Pacific $10,000 that they could not better the record. On April 28, 1869, the CP won the bet!"
