Railroads

Definition

A railroad is a track or set of tracks made of steel rails along which passenger and freight trains run. Railroads were instrumental in the industrial development and westward expansion of the United States during the 19th century.

Analogy

Think about railroads as veins in our body. Just like veins carry blood from one part of our body to another, railroads transport goods and people from one place to another.
