New technology of the Late 1800's

By: Aidan Hudman

Railroads

Railways were introduced in England in the seventeenth century as a way to reduce friction in moving heavily loaded wheeled vehicles. The first North American "gravity road," as it was called, was erected in 1764 for military purposes at the Niagara portage in Lewiston, New York. The builder was Capt. John Montressor, a British engineer known to students of historical cartography as a mapmaker.

Why do we have Time zones

We needed timezones for transport and communication during the 19th century.

Why did we create Airbrakes

The first air brake invented by George Westinghouse revolutionized the railroad industry, making braking a safer venture and thus permitting trains to travel at higher speeds. Westinghouse made many alterations to improve his invention leading to various forms of the automatic brake.

Who's idea was it to build the transcontinental rail road

Who

One of the early and most prominent people making the case for a transcontinental railroad was Asa Whitney. In 1849 he published his ideas on the idea of a railroad that began in Chicago and went to California. There were many others who also joined the chorus.

Union Pacific operates along much of the original Transcontinental Railroad route between Sacramento, Calif., and Omaha, Neb., but it's routes also connect every state from the Mississippi River to the Pacific Ocean.

Why was the transcontinental railroad needed?

Why

Connecting the two American coasts made the economic export of Western resources to Eastern markets easier than ever before. The railroad also facilitated westward expansion, escalating conflicts between Native American tribes and settlers who now had easier access to new territories.

When was the transcontinental railroad in development

WhenBy connecting the existing eastern U.S. rail networks to the west coast, the Transcontinental Railroad (known originally as the "Pacific Railroad") became the first continuous railroad line across the United States. It was constructed between 1863 and 1869

Manufacturing of steel

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel.
