I dont think this was ever used as an officlal option either. Many times Bergen County riders from the Port would go uptown to catch an NJT bus when there were major delays at the Tunnel, but cross honoring in the subway was never an option. They had to swallow the fare. This option makes a lot more sense for nearby Bergen/Hudson riders as opposed to Secaucus Junction especially for riders in Fort Lee, Englewood, Teaneck, Hackensack, etc.
