Amtrak runs a Hudson River line alongside the Lincoln Tunnel. The New York entrance to the path was occupied by a number of the homeless prior to Amtrak’s line, which started operating in 1991. Due to rising buildings and the need for more underground reinforcement, many were forced out and into above-ground shelters. In 2011, the urban explorer Steve Duncan released a video highlighting many of the underground spots remaining in the city and went deep into the tunnels to find many homeless people still living there.
