Freighthopping

In the United States, freighthopping became a common means of transportation following the American Civil War as the railroads began pushing westward, especially among migrant workers who became known as "hobos".

The practice was heralded in popular culture of 20th century America with songs such as "King of the Road", and films like Emperor of the North Pole.

Despite increased deterrent measures, would-be migrants use the Eurostar[4] and Eurotunnel Shuttle[5] to cross the English Channel from France to England.

Union Pacific Railroad in the United States encourages people who witness transients on freight trains to report them to its dispatch center.

[6] It is estimated that yearly between 400,000 and 500,000 migrants—the majority of whom are from El Salvador, Guatemala, and Honduras—hop freight trains in the effort to reach the United States.
