What are railroads?</h3>
Railroad, a kind of land transportation using self-contained engines or locomotives to pull flange-wheeled vehicles over two parallel steel rails or tracks. In the 16th century, railroads were first constructed in European mines using cars pulled by people or animals. The modern railroad evolved swiftly after the steam locomotive was invented and the first railway was built in 1825. The Baltimore and Ohio Railroad, the country's first railroad, started construction in 1828. Specialized railroad vehicles, such as the sleeper cars created by George Pullman in 1859, were constructed to convey both freight and passengers. The railroad impacted every nation's economic and social growth during the 19th century.
When the transcontinental railroad was finished in the United States in 1869, it marked the start of a period of railroad growth and consolidation that included such business titans as Cornelius Vanderbilt, Jay Gould, Edward H. Harriman, James J. Hill, and Leland Stanford. The railroad's significance in the United States started to decline in the early 20th century, although it is still crucial for international travel in Europe, Asia, and Africa. Additionally, see Trans-Siberian Railroad and Orient Express.
