A second station at 10th Avenue and 41st Street was dropped from the plans in October 2007.  The entirety of the extension is located within the New York City borough of Manhattan and is served by the 7 local and <7> express services.  The extension, a key part of the Hudson Yards Redevelopment Project, is expected to bring business and entertainment into the area, as well as aid redevelopment of nearby Chelsea and Hell's Kitchen, located around the Long Island Rail Road's West Side Yard.
