The Skinny on Compression Shorts. by Berkeley Wellness | January 01, 2013. Print. Browse through a sporting-goods store or website, or simply look around a gym or health club, and youâre likely to see the thick, stretchy shorts and tights (and sometimes tops) known as compression garments.
The short answer is that nobody really knows. The Central Pacific Railroad had a maximum of about 12,000 workers at one time, and the Union Pacific probably had a similar number, but people came and went, so the actual number who ever worked is significantly larger, but unknown.
Over 3,200 people are known to have worked on the railroad between 1830 and the end of the Civil War. Many will remain forever anonymous. Perhaps the most outstanding conductor of the Underground Railroad was Harriet Tubman. Born a slave herself, she began working on the railroad to free her family members. During the 1850s, Tubman made 19 separate trips into slave territory. She was terribly serious about her mission.
