Who made the ralroad tracks?

Answer 1

Railroad tracks were constructed by various groups throughout history, including laborers, engineers, and companies involved in the railroad industry. In the United States, significant contributions came from immigrant workers, particularly Irish and Chinese laborers, who built many of the transcontinental railroads in the 19th century. The tracks were designed and overseen by engineers and railroad companies, with major players like the Union Pacific and Central Pacific Railroad leading the construction efforts.
