The Freedom Tunnel is an Amtrak railroad tunnel filled with amazing works of art and homeless people. It obtained its name from a graffiti artist known as Chris "Freedom" Pape.

The Freedom Tunnel is the name given to the railroad tunnel on the West Side Line under Riverside Park in Manhattan, New York City. Currently used by Amtrak trains to and from Pennsylvania Station, it got its name because the graffiti artist Chris "Freedom" Pape used the tunnel walls to create some of his most notable artwork. The name may also be a reference to the former shantytowns built within the tunnel by homeless populations seeking shelter and freedom to live rent-free and unsupervised by law enforcement. The tunnel runs approximately 2.6 miles (4.2 km), from 72nd Street to 124th Street.Provided By: https://en.wikipedia.org/wiki/Freedom_Tunnel
