You can take NJ Transit from NY Penn to Newark Penn as well. Don't have to leave the real Penn Station at all if you're feeling like you don't want to walk or take a train elsewhere. Walk from Newark Penn is slightly longer than going from the Harrison PATH stop but really isn't that much longer. Train ride is usually less than 20 minutes.anyone know how best to get there from Penn Station NY? wonder if there will be shuttles to the stadium from Newark
