railroad and disease

Utilizing the railway system in the United States not only revolutionized the transportation of people, goods, information but also completely changed the transportation of pathogens. The epidemic of this disease is getting worse due to a sharp increase in traffic volume, narrow living space, travel arrangements, and improperly organized health agreements. The lack of public health policy at the time indicated that the United States was not ready to welcome passengers to quiet murderers of railways.

Madeira-Mamoré Railway is an abandoned railroad built between 1907 and 1912 in the Brazilian Rondo region. The railway connects the cities of Porto Velho and Guajará-Mirim. It is called "demonic railroad". Because thousands of construction workers are killing tropical diseases and violence.

Railway construction is the most important of all progress in the transportation revolution. The first batch of railroads transported short-haul cargoes, but the idea of ​​railroads aroused people's interest. Inventors and technicians are hoping to develop railways that can be used to transport goods over long distances and even passengers. In 1826, a group of merchants began the first American rail called Baltimore and Ohio (B & O). Many other companies began building railroads after B & O succeeded in Maryland. However, many problems have arisen. The railroad is expensive and built in a hurry. There were many accidents and delays. In addition, various companies use tracks of various widths, so only certain trains can run on a specific railroad. In 1830, Robert Livingstone Stevens resolved this problem by designing an iron T-shaped track. After this invention, the railroad has grown from 3,000 miles to 30,000 miles in only 20 years.

When the railroad company needed to decide where to build a new railroad, many problems were analyzed. Students read the transcontinental railroad by specializing "railroad history and maps" and then list the geographical, economic, political and social factors that influence the selection of the first transcontinental railroad route can do. In addition, we can discuss the various goals people are trying to achieve through transcontinental railroads. For example, Abraham Lincoln regards the transcontinental railway as a way to unite east and west into a single country, but the architect Theodore D. Judah promised wealth and fame and motivated joint investment. It is a person. In studying the best route, the government appointed Jefferson Davis Minister to investigate possible routes to the Pacific in 1853. Why did the Minister of War pick this job? What is his goal?
