PATH (Port Authority Trans-Hudson) is the Operator of PATH Subway Trains between New York & New Jersey. It Operates PA5's that are similar to NYC Subways R142/A cars. PATH Operates 5 Short Lines: Hoboken (NJ) - 33 St (NY), Hoboken (NJ) - World Trade Center (NY), Journal Sq (NJ) - 33 St (NY), Journal Sq (NJ) - 33 St (NY) (via Hoboken), and Newark (NJ) to World Trade Center (NY). It connects with Amtrak at Newark so dovetail can allow us to switch between the different transit systems to drive either one when we please. PATH PA5 PATH MAP This might be a difficult line for Dovetail to make because the Port Authority of NY/NJ likes to be difficult with people taking pics/videos of tunnels and it might be difficult for them to get the licensing, but there has already been a PATH Simulator back in World of Subways 1 (Based on Pre-2001 NY), so it can't be that difficult...
