Following the destruction of the World Trade Center station in the September 11 attacks , which also required the closing of Exchange Place , the '' ' Hoboken-World Trade Center ' '' branch was suspended . Instead , a temporary branch using the same color code ( green ) operated between Hoboken and Journal Square . When '' ' Exchange Place ' '' reopened on June 29 , 2003 , the green color code was used for the temporary '' ' Hoboken-Exchange Place ' '' branch . The '' ' Hoboken-World Trade Center ' '' branch was restored when the temporary '' ' World Trade Center ' '' station opened on November 23 . On April 9 , 2006 , weekend service on this branch was discontinued to accommodate long-term construction on the World Trade Center site
