The Underground Railroad was the first great freedom movement in the Americas.
The movement started in Columbia, Pennsylvania in 1804 by a Quaker abolitionist named Levi Coffin. He used railroad terminology to confuse the slave catchers.
A person leading the fugitives to freedom would be known as CONDUCTOR. It would be their responsibility to get the PASSENGERS(fugitives), fom one Station(safehouse) to another
until they would eventually reach a TERMINAL in northern U.S or Canada, where there was freedom.
Sometimes Fugitives would be transported from one station to another in false-bottom wagons, such as the one you see on the screen
